I. Self-Regulatory Organization's Statement of the Terms of Substance 
of the Proposed Rule Change

    The Exchange proposes to amend the Exchange's Rulebook to provide 
for the Exchange to trade NMS stocks and exchange traded products 23 
hours per day, five days per week. This Amendment No. 2 to SR-NASDAQ-
2025-109 supersedes and replaces Amendment No. 1 to SR-NASDAQ-2025-109 
in its entirety, which superseded the original filing in its 
entirety.\9\
---------------------------------------------------------------------------

    \9\ See Amendment No. 3, supra note 8. The Exchange filed and 
subsequently withdrew Amendment No. 1 to SR-NASDAQ-2025-109 on March 
12, 2026.
---------------------------------------------------------------------------

    The text of the proposed rule change is available on the Exchange's 
website at <a href="https://listingcenter.nasdaq.com/rulebook/nasdaq/rulefilings">https://listingcenter.nasdaq.com/rulebook/nasdaq/rulefilings</a>, and at the principal office of the Exchange.

II. Self-Regulatory Organization's Statement of the Purpose of, and 
Statutory Basis for, the Proposed Rule Change

    In its filing with the Commission, the Exchange included statements 
concerning the purpose of and basis for the proposed rule change and 
discussed any comments it received on the proposed rule change. The 
text of these statements may be examined at the places specified in 
Item IV below. The Exchange has prepared summaries, set forth in 
sections A, B, and C below, of the most significant aspects of such 
statements.

A. Self-Regulatory Organization's Statement of the Purpose of, and 
Statutory Basis for, the Proposed Rule Change

1. Purpose
    The purpose of the proposed rule change is to amend the Exchange's 
Rulebook to provide for the Exchange to trade NMS stocks and exchange 
traded products (``ETPs'') on a 23 hours per day, five days per week 
basis (``23/5'').
Background and Overview
    The history of the U.S. equities markets is one marked by 
successive waves of change and technological innovation. Among other 
things, these changes and innovations included the automation of 
trading and the introductions of decimalization, algorithmic trading, 
and colocation. When these innovations arose, they spurred equity 
market structure to evolve to accommodate them. The latest change to 
impact the markets is rising investor interest in trading U.S. equities 
during overnight hours, especially among investors located outside of 
the United States.\10\ To align Nasdaq with emerging investor interest 
in trading outside of traditional U.S. market hours, Nasdaq now 
proposes to extend its hours for trading NMS stocks and ETPs on the 
Exchange from 16 hours per day, 5 days per week, to 23 hours per day, 5 
days per week.
---------------------------------------------------------------------------

    \10\ Certain alternative trading systems (``ATS''), such as Blue 
Ocean, already trade securities on an overnight basis. Meanwhile, 
the Commission has approved several new and existing exchanges to 
securities on an extended overnight basis, but none has begun to do 
so. See Securities Exchange Act Release No. 34-102400 (Feb. 11, 
2025); 90 FR 9794 (Feb. 18, 2025) (order approving NYSE Arca Inc. 
proposal to lengthen its trading session to 22 hours per day, 5 days 
per week) (``NYSE Arca Approval Order''); Securities Exchange Act. 
Release No. 89-235 [sic] (Nov. 27, 2024); 89 FR 97092 (order 
approving application of 24X National Exchange, LLC for registration 
as a national securities exchange and to trade 23 hours per day, 5 
days per week) (``24X Approval Order'').
---------------------------------------------------------------------------

    Nasdaq has designed its proposal for 23/5 trading carefully. We 
have solicited and we continue to solicit feedback from those who stand 
to be impacted most by the proposal, including Nasdaq's listed 
companies and market participants. Nasdaq is also an active participant 
in ongoing industry discussions about how to address, in a coordinated 
manner, market protections, halts, and corporate actions.
    By way of background, Nasdaq presently trades securities in three 
daily sessions during each weekday from Monday through Friday. First, 
Nasdaq operates a Pre-Market Hours session from 4:00 a.m. to 9:30 a.m. 
ET.\11\ Second, commencing at 9:30 a.m. with the execution of the 
Nasdaq Opening Cross, Nasdaq conducts its Regular Market Hours trading 
session until 4:00 p.m.\12\ Third, commencing at 4:00 p.m. with the 
execution of the Nasdaq Closing Cross, Nasdaq conducts a Post-Market 
Hours \13\ trading session until 8:00 p.m.\14\ During weekdays, between 
the hours of 8:00 p.m.-4:00 a.m. ET, the Exchange is closed to trading 
as it is during all weekend hours.
---------------------------------------------------------------------------

    \11\ See Rule Equity 1, Section 1(a)(9) (defining the term 
``Pre-Market Hours'' as ``the period of time beginning at 4:00 a.m. 
ET and ending immediately prior to the commencement of Market 
Hours.). As discussed below, the Exchange is proposing non-
substantive changes to this rule.
    \12\ See Rule Equity 1, Section 1(a)(9) (defining the term 
``Market Hours'' as the period of time beginning at 9:30 a.m. ET and 
ending at 4:00 p.m. ET or such earlier time as may be designated by 
Nasdaq on a day when Nasdaq closes early). As discussed below, the 
Exchange proposes to rename this session ``Regular Market Hours'' 
and make other non-substantive conforming changes to this rule.
    \13\ See Rule Equity 1, Section 1(a)(9) (defining the term 
``Post-Market Hours'' as the period of time beginning immediately 
after the end of Market Hours and ending at 8:00 p.m. ET). As 
discussed below, the Exchange is proposing non-substantive changes 
to this rule.
    \14\ The Exchange uses different terms to describe each of its 
trading sessions. For example, to refer to its pre-market hours 
session, the Exchange uses varying terms, such as ``Pre-Market,'' 
``Early Market Hours,'' or ``Early Market.'' And to refer to its 
post-market hours session, the Exchange uses varying terms, such as 
``Post-Market,'' ``Extended Hours,'' and ``Extended Market Hours.'' 
As part of this filing, the Exchange proposes to harmonize disparate 
and inconsistent references to these concepts to avoid confusion. 
Throughout the Rulebook, as amended, the Exchange proposes to define 
the terms ``Pre-Market Hours'' and ``Post-Market Hours'' exclusively 
to refer to those specific trading periods. In addition, the 
Exchange proposes to define the term ``Extended Hours'' to refer 
more generally to trading that occurs outside of Regular Market 
Hours. See proposed Rule 1, Equity 1, Sections 1(a)(20)-(21) and 
(23) (defining the terms ``Pre-Market Hours,'' ``Post-Market 
Hours,'' and ``Extended Hours,'' respectively).
---------------------------------------------------------------------------

    During its current Pre-Market and Post-Market trading sessions, 
Nasdaq offers more limited trading functionality than it does during 
the Regular Market Hours trading session and trading during that period 
is subject to different regulation. For example, outside of ``regular 
trading hours,'' \15\ only certain aspects of the SEC's Regulation 
National Market System (``Reg. NMS'') \16\ apply. Meanwhile, the 
Exchange does not offer certain order types during these trading

[[Page 20224]]

sessions, such as unpriced orders and pegged orders. Moreover, during 
extended hours trading sessions, liquidity tends to be lower than it is 
during regular trading hours. Additionally, stocks often experience 
more volatile trading activity during these sessions. For reasons such 
as those described above, Exchange members may not accept an order from 
a customer for execution in these extended hours trading sessions 
without disclosing to such customer that extended hours trading 
involves material risks.\17\ Similarly, to the extent that markets like 
Nasdaq allow trading to occur in extended hours trading sessions, FINRA 
requires brokers that participate in these sessions to affirmatively 
disclose to investors that extended hours trading carries greater risks 
than trading during regular market hours.\18\
---------------------------------------------------------------------------

    \15\ See 17 CFR 242.600(b)(88) (defining the term ``regular 
trading hours'' to mean 9:30 a.m.-4 p.m. Eastern Time).
    \16\ 17 CFR 242.600-614.
    \17\ See Rule Equity 2, Section 20 (``Customer Disclosures'') 
(providing, in part, that ``[n]o member may accept an order from a 
customer for execution in the premarket session or post-market 
session without disclosing to such customer that extended hours 
trading involves material trading risks, including the possibility 
of lower liquidity, high volatility, changing prices, unlinked 
markets, an exaggerated effect from news announcements, wider 
spreads and any other relevant risk. The absence of an updated 
underlying index value or intraday indicative value is an additional 
trading risk in extended hours for Derivative Securities 
Products''). As discussed below and consistent with the approved 
rules of other exchanges for operating an overnight session, the 
Exchange is proposing to supplement these disclosures to address 
additional risks associated with the proposed Night Session. See 
infra note 72 and accompanying text.
    \18\ See FINRA Rule 2265 (Extended Hours Trading Risk 
Disclosure).
---------------------------------------------------------------------------

    Although trading volume in extended hours trading tends to be 
considerably lower than it is during regular market hours, Nasdaq has 
observed a growing interest in trading during overnight hours, 
particular among investors located in Asia and other foreign 
jurisdictions where business hours do not coincide, fully or otherwise, 
with U.S. regular market hours. For these investors, extended market 
hours trading sessions often provide some real-time access to Nasdaq 
during their business hours, but for many, Nasdaq is closed during 
hours when they are most apt to trade. Increasingly, these investors 
are turning to ATSs that offer overnight trading, such as Blue Ocean, 
Bruce, Interactive Brokers, and OTC Moon. They are also increasingly 
utilizing trading platforms that provide access to markets for digital 
assets, including cryptocurrencies, tokenized assets, and tokenized 
securities, on a 24/7 basis. Nasdaq submits its proposal to extend its 
trading hours to compete for order flow from these investors, as well 
as to position itself favorably in the future to participate in markets 
that trade digital assets.
Overview of Nasdaq's Proposal for 23/5 Trading
    Going forward, Nasdaq proposes to conduct trading 23 hours per day, 
5 days per week. It proposes doing so in two trading sessions rather 
than three. First, it will conduct a ``Day'' trading session, which 
will be the same and comprise its existing Pre-Market Hours, Regular 
Market Hours, and Post-Market Hours trading sessions.\19\ The Day 
Session will commence at 4:00 a.m. ET and end at 8:00 p.m. ET, and it 
will continue to feature both the Nasdaq Opening Cross and the Nasdaq 
Closing Cross. Second, Nasdaq will conduct a ``Night'' trading session, 
which will commence at 9:00 p.m. ET and end at 4:00 a.m. ET the next 
calendar day.\20\ All NMS Stocks would be eligible to trade during the 
proposed Night Session. As we explain below, between 8:00 p.m. and 9:00 
p.m. ET on each weekday, the Exchange will pause trading on its market 
to conduct maintenance, testing, and to process those corporate 
actions, such as mergers, stock splits, and dividends, that will become 
effective the following trading day. The pause will also allow for 
market participants to process and clear trades before proceeding to a 
new trading day. Nasdaq proposes to keep its markets closed during all 
weekend hours, except that the trading week will commence with a Night 
Session on Sunday nights at 9:00 p.m. ET.\21\ The trading week will end 
at the conclusion of the Day Session on Friday.\22\
---------------------------------------------------------------------------

    \19\ See Rule Equity 1, Section 1(a)(9).
    \20\ See proposed Rule Equity 1, Section 1(a)(19) (defining the 
term ``Night Session'' as ``the time between 9:00 p.m. on one 
calendar day through 4:00 a.m. the next calendar day Sunday through 
Thursday provided that each such next calendar day is a Business 
Day.''). To enhance clarity and consistent with approved rules of 
other national securities exchanges, and specifically 24X, the 
Exchange proposes to define the term ``Business Day'' to means any 
Monday, Tuesday, Wednesday, Thursday or Friday other than any of the 
following U.S. holidays if they are celebrated on a Monday, Tuesday, 
Wednesday, Thursday or Friday: New Year's Day, Martin Luther King 
Jr. Day, Presidents' Day, Good Friday, Memorial Day, Juneteenth 
National Independence Day, Independence Day, Labor Day, Thanksgiving 
Day and Christmas Day ET, or such other U.S. holiday(s) as published 
by the Exchange from time to time). See proposed Rule Equity 1, 
Section 1(a)(17).
    \21\ See proposed Rule Equity 1, Section 1(a)(19) (defining the 
term ``Night Session'').
    \22\ See proposed Rule Equity 1, Section 1(a)(18). The Exchange 
proposes a non-substantive change to define the term ``Day Session'' 
in proposed Rule 1 Equity 1, Section 1(a)(18) as follows: ``[t]he 
term `Day Session' means the time between 4:00 a.m. ET and 8:00 p.m. 
ET on Business Days, during which period the Pre-Market Hours, 
Regular Market Hours and Post-Market Hours are in operation.'' The 
Exchange believes this non-substantive change is designed to 
facilitate application of the rules by combining references to the 
three current trading sessions into one broader day trading session 
for referencing purposes only thereby simplifying the 
conceptualization and application of the proposed rules. See id.
---------------------------------------------------------------------------

    On a holiday or another day when the Exchange is closed for 
business, the closure will be effective as of 8:00 p.m. ET on the 
calendar day prior to the closure date, and the market will reopen at 
9:00 p.m. ET on the closure date, unless the closure date is a Friday, 
in which case the market will reopen on Sunday evening at 9:00 p.m. 
ET.\23\ On a day when Nasdaq closes the market early, it will resume 
trading at 9:00 p.m. ET on the same calendar day, unless again, the 
early closure date is a Friday, in which case the Exchange will resume 
trading on Sunday evening at 9:00 p.m. ET.\24\
---------------------------------------------------------------------------

    \23\ See proposed Rule Equity 1, Section 1(a)(19).
    \24\ See proposed Rule Equity 1, Section 1(a)(19).
---------------------------------------------------------------------------

    Consistent with the approved rules of other national securities 
exchanges that are similarly proposing to extend their trading hours 
overnight,\25\ Nasdaq proposes to launch the operation of its 23/5 
market upon the availability of the Securities Information Processor 
(``SIP'') to operate during the Night Session.\26\
---------------------------------------------------------------------------

    \25\ See 24X Approval Order, supra note 10, 89 FR at 97105-07 
(approving application of 24X to trade overnight provided that it 
may not begin doing so until the Equity Data Plans have announced 
their preparedness to collect, consolidate, process, and disseminate 
quotation and transaction information during the overnight hours; 
the SEC would nullify approval of 24X rules governing overnight 
trading if such readiness does not occur within 18 months of the 
issuance of the approval order); NYSE Arca Approval Order, supra 
note 1010. See also 24X Rule 1.5(c); NYSE Arca Rule 7.34-E.
    \26\ See proposed Rule Equity 1, Section 1(19) (defining the 
term ``Night Session'' and further providing that (1) the Exchange 
shall not commence operation of the Night Session unless the Equity 
Data Plans (1) have established a mechanism to collect, consolidate, 
process and disseminate quotation and transaction information at all 
times during the Night Session that is equivalent to the mechanism 
established for Exchange trading hours during Regular Market Hours, 
and (2) have provided the Exchange with notification that they are 
prepared to collect, consolidate, process and disseminate quotation 
and transaction information to accommodate the Night Session; (2) 
that prior to commencing operation during the Night Session, the 
Exchange will file a proposed rule change pursuant to Section 19(b) 
of the Exchange Act and the rules thereunder to amend its rules 
confirming that the Exchange is able to comply with its obligations 
under the Exchange Act and the rules thereunder during the Night 
Session and that such Equity Data Plans are prepared to collect, 
consolidate, process and disseminate quotation and transaction 
information at all times during the Night Session (``Night Session 
Proposed Rule Change''); and (3) that if the Night Session Proposed 
Rule Change is not filed within 18 months of the SEC's approval of 
this proposed rule change, the Exchange will promptly file a 
proposed rule change to remove the rules that apply to the Night 
Session). See id.
---------------------------------------------------------------------------

    To facilitate this proposal to extend Nasdaq's trading hours, 
Nasdaq

[[Page 20225]]

proposes to amend numerous rules in its Rulebook. Rather than catalogue 
all such proposed changes, the majority of which are non-substantive 
changes to reflect revised trading times, we focus below on describing 
only those changes that will have a material impact on the operation of 
the Nasdaq Stock Market.
    Before we describe what Nasdaq proposes to change, we first want to 
make clear what will remain the same. The following aspects of Nasdaq's 
trading system and procedures will not change when trading equities and 
ETPs on a 23/5 basis: \27\
---------------------------------------------------------------------------

    \27\ The Exchange will report the best bid and offer on the 
Exchange to the appropriate network processor, as it currently does 
today, using the same formats and delivery mechanisms. As is the 
case today, trades executed and reported outside of Regular Market 
Hours as proposed will be reported to the appropriate network 
processor with the ``.T'' modifier or as otherwise required by the 
Equity Data Plans. No fee changes are proposed in connection with 
this proposal.

<bullet> Listing rules
<bullet> Membership rules
<bullet> Rules of conduct
<bullet> Market Maker obligations
<bullet> Ranking, display, priority and decrementation rules
<bullet> Disciplinary rules and enforcement
<bullet> Opening and Closing Crosses
<bullet> Clearly Erroneous protections
The ``Day'' Trading Session
    The new Day trading session will combine and incorporate, without 
substantive changes, all elements of what are now the Pre-Market 
Hours,\28\ Regular Market Hours,\29\ and Post-Market Hours \30\ trading 
sessions. Going forward, the Rules will delineate these sessions as 
distinct sub-parts of the Day Session.\31\ During the Day Session, all 
existing requirements, procedures, behaviors and processes, including 
those governing the Opening and Closing Crosses, halts, routing, order 
types, attributes, times-in-force, order entry protocols, connectivity, 
market data, etc., all will persist in their current form, with only 
minor conforming changes (described below). For example, Order Type 
availability and behavior in the Pre-Market Hours of 4:00-9:30 a.m. ET 
will remain the same going forward as it is now.\32\ As another 
example, limits on Order Type availability in Post-Market trading will 
continue to apply.\33\
---------------------------------------------------------------------------

    \28\ See Rule Equity 1, Section 1(a)(9) (defining the terms 
``Market Hours,'' ``Pre-Market Hours,'' and ``Post-Market Hours''). 
To effect this change, the Exchange proposes a non-substantive term 
to define the term ``Pre-Market Hours'' as that subset of the Day 
Session comprising the trading session that begins at 4:00 a.m. and 
continues until 9:30 a.m. on Business Days. See proposed Rule Equity 
1, Section 1(a)(20).
    \29\ See Rule Equity 1, Section 1(a)(9). To effect this change, 
the Exchange proposes a non-substantive change to the current 
definition of ``market hours'' to provide that, except as otherwise 
provided in Rule 4120, the term ``Regular Market Hours'' means that 
subset of the Day Session comprising the trading session that begins 
at 9:30 a.m. and continues until 4:00 p.m. on Business Days. See 
proposed Rule Equity 1, Section 1(a)(22).
    \30\ See Rule Equity 1, Section 1(a)(9). To effect this change, 
the Exchange proposes a non-substantive term to define the term 
``Post-Market Hours'' as that subset of the Day Session comprising 
the trading session that begins at 4:00 p.m. and that continues 
until 8:00 p.m. on Business Days except as otherwise provided in 
Rule 4120. See proposed Rule Equity 1, Section 1(a)(21).
    \31\ See proposed Rule Equity 1, Sections 1(a)(18), and (20)-
(21).
    \32\ See proposed Rule 4702. In Amendment No. 2 to the proposed 
rule change, the Exchange updates Exhibit 5 to the proposal to 
reflect changes to Rule 4702 that were adopted after the date of the 
initial filing. See, e.g., Notice, supra note 3; Exchange Rule 4702.
    \33\ See proposed Rule 4702. Consistent with the behavior of 
such order during extended hours, the Exchange proposes to amend 
Rule 4702(b)(3)(A), that during the Night Session, as is the case 
during Pre- and Post-Market Hours, a Non-Displayed Order will be 
posted at its entered limit price without adjustment. See proposed 
Rule 4702(b)(3)(A). The Exchange further proposes to amend Rule 
4702(b)(4) to provide that, during the Night Session, as is the case 
today with respect to the Pre- and Post-Market Hours, a Post-Only 
Order will be processed in a manner identical to Regular Market 
Hours with respect to locking or crossing Orders on the Nasdaq Book, 
but will not be cancelled or have its price adjusted with respect to 
locking or crossing the quotations of other market centers. See 
proposed Rule 4702(b)(4). The Exchange believes this proposed change 
is appropriate because the Night Session is effectively an extension 
of the Exchange's current extended hours, and this proposed change 
conforms the behavior of this order during the current extended 
hours through the hours of operation of the Night Session, as 
proposed.
---------------------------------------------------------------------------

The ``Night'' Trading Session
    By contrast to the Day trading session, the proposed Night trading 
session will be an entirely new trading session that will cover a 
period of the night in the Eastern Time Zone in the United States in 
which trading on the Exchange does not now occur.\34\ As discussed 
above, all NMS Stocks would be eligible to trade in the proposed Night 
Session. In many ways, the Night Session will be like the existing 
Post-Market Hours and Pre-Market Hours trading sessions in that it will 
feature limited functionality to reflect that only certain rules of 
Reg. NMS apply and the reduced trading activity. The Night Session will 
also feature a limited number of Order Types and Attributes.\35\ Only 
limit orders would be permitted during the Night Session.\36\ Unpriced 
orders would not be permitted.\37\ Moreover, limit orders entered 
during the Night Session would be subject to Limit Order Protection 
(``LOP'') as provided under subparagraph (c) of Equity 4, Rule 4757. 
LOP is a feature of the Nasdaq Market Center that prevents certain 
Limit Orders at prices outside of pre-set standard limits (``LOP 
Limit'') from being accepted by the System.\38\ The LOP Limit is the 
greater of 10% of the

[[Page 20226]]

LOP Reference Price \39\ or $0.50 for all securities across all trading 
sessions.\40\
---------------------------------------------------------------------------

    \34\ See proposed Rule 1 Equity, Section 1(a)(19).
    \35\ As discussed below, all limit orders permitted to trade 
during Pre-Market Hours will be eligible to trade in the Night 
Session; provided, however, that order types designated for the 
opening cross or post-opening trading that are permitted during the 
Pre-Market Hours will not be accepted during the Night Session. As 
further discussed below, the following orders will also not be 
permitted during the Night Session: Company Direct Listing, Extended 
Trading Close, Midpoint Peg Post-Only, M-ELO, and M-ELO+C. To effect 
these changes, the Exchange proposes to modify Rule 4702 as follows. 
The Exchange proposes to modify Rule 4702(b)(1)(A) (``Price to 
Comply Order'') to add ``and during the Night Session'' to the 
sentence currently providing that ``During Pre-Market Hours and 
Post-Market Hours, a Price to Comply Order will be ranked and 
displayed at its entered limit price without adjustment.'' As 
proposed, during the Night Session, Price to Comply Orders would 
thus be ranked and displayed in the same manner in which such orders 
are ranked and displayed during the Pre-Market and Post-Market Hours 
today. The Exchange further proposes a conforming change to delete 
the word ``and'' and add commas in that sentence as appropriate. In 
addition, the Exchange proposes a non-substantive, technical 
amendment to the first paragraph of Rule 4702(b)(1)(A) to update the 
cross-reference to Rule 610(d) of Regulation NMS, governing locking 
and crossing quotations, to the correct cross-reference, Rule 610(e) 
of Regulation NMS. With respect to Rule 4702(b)(2)(A) (``Price to 
Display Order''), the Exchange proposes three changes. First, the 
Exchange proposes to add ``and during the Night Session'' to the 
sentence currently providing that ``During Pre-Market Hours and 
Post-Market Hours, a Price to Display Order will be displayed and 
ranked at its entered limit price without adjustment.'' As proposed, 
during the Night Session, Price to Display Orders would thus be 
ranked and displayed in the same manner in which such orders are 
ranked and display during the Pre-Market and Post-Market Hours 
today. Second, the Exchange further proposes a conforming change to 
delete the word ``and'' and add commas in that sentence as 
appropriate. Finally, the Exchange proposes to insert ``Regular'' 
before ``Market Hours'' to reflect the proposed renaming of the 
regular market section under Rule Equity 1, Sectio 1(a)(22). See 
proposed Rule 4702.
    \36\ See Rule 4702 (``Order Types'') as proposed.
    \37\ See proposed Rule 4702(a). To effect this change, the 
Exchange proposes to insert, immediately following the proposed 
entry addressing ``Night Session Ports, Protocols'' in Rule 4702(a) 
the following text: ``Unpriced orders are not permitted during the 
Night Session. Unpriced orders designated for the Night Session will 
be rejected.'' See id.
    \38\ See Rule 4757(c). LOP applies to all Quotes and Orders, 
including Quotes and Orders that have been modified, where the 
modification results in a new timestamp and priority. LOP does not 
apply to Orders with Market and Primary Pegging, Market Maker Peg 
Orders or Intermarket Sweep Orders. A Midpoint Pegging Order with a 
discretion price would not be subject to LOP. LOP is operational 
each trading day, except for orders designated for opening, 
reopening and closing crosses and initial public offerings. LOP is 
not operational during trading halts and pauses. LOP would not apply 
in the event there is no established LOP Reference Price or the 
National Best Bid, when used as the LOP Reference Price, is equal to 
or less than $0. See Rule 4757(c)(i).
    \39\ The ``LOP Reference Price'' is the current National Best 
Bid or Best Offer, the bid for sell orders and the offer for buy 
orders. See Rule 4757(c)(iii). LOP will reject incoming Limit Orders 
that exceed the LOP Reference Threshold. Limit Orders will be 
rejected if the price of the Limit Order is greater than the LOP 
Reference Threshold for a buy Limit Order. Limit Orders will be 
rejected if the price of the Limit Order is less than the LOP 
Reference Threshold for a sell Limit Order. See Rule 4757(c)(v). As 
provided under Rule 4757(c)(iv), the LOP Reference Threshold for buy 
orders will be the LOP Reference Price (offer) plus the applicable 
LOP Limit. The LOP Reference Threshold for sell orders will be the 
LOP Reference Price (bid) minus the applicable LOP Limit.
    \40\ See Rule 4757(c)(ii).
---------------------------------------------------------------------------

    Specifically, the following Order Types will not be available 
during the Night Session: Supplemental; \41\ Market Maker Peg; \42\ 
Market On Open (``MOO''); \43\ Limit on Open (``LOO''); \44\ Opening 
Imbalance Only (``OIO Order''); \45\ Market on Close (``MOC Order''); 
\46\ Limit on Close (``LOC Order''); \47\ Imbalance-Only (``IO 
Order''); \48\ Company Direct Listing; \49\ Extended Trading Close; 
\50\ Midpoint Peg Post-Only; \51\ Midpoint Extended Life Order (``M-
ELO''); \52\ and Midpoint Extended Life Order Plus Continuous Book 
(``M-ELO+CB Order'').\53\
---------------------------------------------------------------------------

    \41\ A ``Supplemental Order'' is an Order Type with a Non-
Display Order Attribute that is held on the Nasdaq Book in order to 
provide liquidity at the NBBO through a special execution process 
described in Rule 4757(a)(1)(D). A Supplemental Order may be entered 
at any time during Pre-Market Hours, or Regular Market Hours, but is 
available for potential execution only during Market Hours. Any 
Supplemental Orders still on the Nasdaq Book at the conclusion of 
Market Hours will be cancelled. See Rule 4702(b)(6).
    \42\ A ``Market Maker Peg Order'' is an Order Type designed to 
allow a Market Maker to maintain a continuous two-sided quotation at 
a displayed price that is compliant with the quotation requirements 
for Market Makers set forth in Rule Equity 2, Section 5(a)(2). The 
Exchange is proposing to provide that Market Maker Peg Orders are 
not available during the Night Session, and, further, that Market 
Maker Peg Orders designated for the Night Session will be cancelled. 
See proposed Rule 4702(b)(7)(A).
    \43\ A ``Market On Open Order'' or ``MOO Order'' is an Order 
Type entered without a price that may be executed only during the 
Nasdaq Opening Cross. Subject to the qualifications provided in Rule 
4702(b)(8), MOO Orders may be entered between 4 a.m. ET and 
immediately prior to 9:28 a.m. ET. An MOO Order will execute only at 
the price determined by the Nasdaq Opening Cross. See Rule 
4702(b)(8).
    \44\ A ``Limit On Open Order'' or ``LOO Order'' is an Order Type 
entered with a price that may be executed only in the Nasdaq Opening 
Cross, and only if the price determined by the Nasdaq Opening Cross 
is equal to or better than the price at which the LOO Order was 
entered. Subject to the qualifications provided in Rule 4702(b)(9), 
LOO Orders may be entered between 4 a.m. ET and immediately prior to 
9:28 a.m. See Rule 4702(b)(9).
    \45\ An ``Opening Imbalance Only Order'' or ``OIO Order'' is an 
Order Type entered with a price that may be executed only in the 
Nasdaq Opening Cross and only against MOO Orders, LOO Orders, or 
Early Market Hours Orders (as defined in Rule 4752). OIO Orders may 
be entered between 4:00 a.m. ET until the time of execution of the 
Nasdaq Opening Cross, but may not be cancelled or modified at or 
after 9:25 a.m. ET. See Rule 4702(b)(10)(A).
    \46\ A ``Market On Close Order'' or ``MOC Order'' is an Order 
Type entered without a price that may be executed only during the 
Nasdaq Closing Cross. Subject to the qualifications provided in Rule 
4702(b)(11)), MOC Orders may be entered between 4 a.m. ET and 
immediately prior to 3:55 p.m. See Rule 4702(b)(11).
    \47\ A ``Limit On Close Order'' or ``LOC Order'' is an Order 
Type entered with a price that may be executed only in the Nasdaq 
Closing Cross and only if the price determined by the Nasdaq Closing 
Cross is equal to or better than the price at which the LOC Order 
was entered, subject to qualifications set out in Rule 4702(b)(12). 
Subject to qualifications set out in the Rule, LOC Orders may be 
entered, cancelled, and/or modified between 4 a.m. ET and 
immediately prior to 3:50 p.m. ET. . See Rule 4702(b)(12).
    \48\ An ``Imbalance Only Order'' or ``IO Order'' is an Order 
entered with a price that may be executed only in the Nasdaq Closing 
Cross and only against MOC Orders or LOC Orders. IO Orders may be 
entered between 4:00 a.m. ET until the time of execution of the 
Nasdaq Closing Cross. See Rule 4702(b)(13).
    \49\ A ``Company Direct Listing Order'' or ``CDL Order'' is a 
``market order'' entered without a price that may be executed only 
in the Nasdaq Halt Cross for a Direct Listing with a Capital Raise 
(as defined in Listing Rule IM-5315-2). See Rule 4702(b)(16). The 
Exchange proposes to amend Rule 4702(b)(16)(A) to provide that CDL 
Orders are not eligible to participate in the Night Session, and, 
further, that CDL Orders designated for the Night Session will be 
rejected. See proposed Rule 4702(b)(16)(A).
    \50\ An ``Extended Trading Close'' or ``ETC'' Order is an Order 
Type applicable to Nasdaq-listed securities that may be executed 
only during the Extended Trading Close and only at the Nasdaq 
Official Closing Price, as determined by the Nasdaq Closing Cross. 
See Rule 4702(b)(17). The Exchange proposes to amend Rule 
4702(b)(17) to provide that ETC Orders are not eligible to 
participate in the Night Session, and that ETC Orders designated for 
the Night Session will be rejected. See proposed Rule 
4702(b)(17)(A).
    \51\ A ``Midpoint Peg Post-Only Order'' (``MPPO'') is an Order 
Type with a Non-Display Order Attribute that is priced at the 
midpoint between the NBBO and that will execute upon entry only in 
circumstances where economically beneficial to the party entering 
the Order. The Midpoint Peg Post-Only Order is available during 
Market Hours only. See Rule 4702(b)(5).
    \52\ A ``Midpoint Extended Life Order'' is an Order Type with a 
Non-Display Order Attribute that is priced at the midpoint between 
the NBBO and that will not be eligible to execute until a minimum 
time period has passed after acceptance of the order by the System. 
Eligible Midpoint Extended Life Orders may only execute against 
other eligible Midpoint Extended Life Orders and M-ELO+CB Orders. 
See Rule 4702(b)(14). The Exchange proposes to amend subparagraph 
(A) of Rule 4702(b)(14) to provide that Midpoint Extended Life 
Orders are not eligible to participate in the Night Session, and 
that Midpoint Extended Life Orders designated for the Night Session 
will be rejected. The Exchange also proposes to modify subparagraph 
(B) of Rule 4702(b)(14) (addressing Order Attributes that may be 
assigned to a Midpoint Extended Life Order) to provide, consistent 
with the foregoing proposed changes, that ``Midpoint Extended Life 
Orders designated for the Night Session will be rejected.'' See 
proposed Rule 4702(b)(14)(A)-(B).
    \53\ A ``Midpoint Extended Life Order Plus Continuous Book'' or 
``M-ELO+CB'' is an Order Type that has all of the characteristics 
and attributes of a Midpoint Extended Life Order, except that a M-
ELO+CB that satisfies a specified holding period is eligible to 
execute (at the midpoint of the NBBO) against other eligible M-
ELO+CBs, eligible Midpoint Extended Life Orders, and as described in 
the rule, Non-Displayed Orders with Midpoint Pegging resting on the 
Exchange's Continuous Book. See Rule 4702(b)(15). The Exchange 
proposes to amend subparagraph (A) of Rule 4702(b)(15) to provide 
that M-ELO+CB orders are not eligible to participate in the Night 
Session, and that M-ELO+CB orders designated for the Night Session 
will be rejected. See proposed Rule 4702(b)(15)(A).
---------------------------------------------------------------------------

    As proposed, orders for the Night Session may be entered into the 
System (or previously entered orders cancelled or modified) from 9:00 
p.m. ET until 4:00 a.m. ET in accordance with the hours of operation 
for the Night Session.\54\
---------------------------------------------------------------------------

    \54\ To effect this change, the Exchange proposes to provide in 
Rule 4756(a)(3) that orders for the Night Session may be entered 
into the System (or previously entered Orders cancelled or modified) 
from 9 p.m. until 4:00 a.m. ET in accordance with the hours of 
operation for the Night Session. See proposed Rule 4756(b). The 
Exchange further proposes to provide in Rule 4120(a)(10)(C) that the 
Exchange will begin accepting orders for the Night Session at 9:00 
p.m. ET in accordance with Rule 4756 and will trade thereafter 
through the Night Session. Similarly, and with respect to entry of 
quotes by Nasdaq Market Makers, the Exchange proposes to provide 
that during the Night Session, Nasdaq Market Makers and Nasdaq ECNs 
can enter quotes into the System from 9:00 p.m. ET to 4:00 a.m. ET. 
See proposed Rules 4756(a))(10)(C), 4756(b).
---------------------------------------------------------------------------

    Similarly, the following Order Attributes \55\ will not be 
available during the Night Session: Primary Pegging; \56\Market 
Pegging; \57\ Midpoint Pegging; \58\ and Discretion (Pegging).\59\

[[Page 20227]]

With respect to Time-in-Force \60\ order attributes, orders entered 
during the Night Session that are designated to deactivate after 4:00 
a.m. ET will deactivate at the conclusion of the Night Session at 4:00 
a.m. ET.\61\
---------------------------------------------------------------------------

    \55\ In Amendment No. 2 to the proposed rule change, the 
Exchange updates Exhibit 5 to the proposal to reflect changes to 
Rule 4703 that were adopted after the date of the initial filing. 
See, e.g., Notice, supra note 3; Exchange Rule 4703.
    \56\ See Rule 4703(d). Pegging is an Order Attribute that allows 
an Order to have its price automatically set with reference to the 
National Best Bid and Offer; provided, however, that if Nasdaq is 
the sole market center at the Best Bid or Best Offer (as 
applicable), then the price of any Displayed Order with Primary 
Pegging will be set with reference to the highest bid or lowest 
offer disseminated by a market center other than Nasdaq. Pegging is 
available only during Market Hours. Nasdaq offers three varieties of 
Pegging: Primary Pegging, Market Pegging, and Midpoint Pegging. 
Primary Pegging means Pegging with reference to the Inside Quotation 
on the same side of the market. See id.
    \57\ Market Pegging means Pegging with reference to the Inside 
Quotation on the opposite side of the market. Pegging is available 
only during Regular Market Hours. See Rule 4703(d).
    \58\ See Rule 4703(d). Midpoint Pegging means Pegging with 
reference to the midpoint between the Inside Bid and the Inside 
Offer. Pegging is available only during Regular Market Hours. See 
id.
    \59\ Discretion is an Order Attribute under which an Order has a 
non-displayed discretionary price range within which the entering 
Participant is willing to trade; such an Order may be referred to as 
a ``Discretionary Order.'' The Discretion Order Attribute may be 
combined with the Pegging Order Attribute, in which case either the 
price of the Order or the discretionary price range or both may be 
pegged in the ways described in Rule 4702(d) with respect to the 
Pegging Order Attribute. As discussed above, however, and consistent 
with its proposal with respect to the Pegging order attribute during 
the Night Session, the Exchange proposes to provide that during the 
Night Session, the Discretion attribute may not be combined with the 
Pegging Order attribute. See proposed Rule 4703(g) (providing that 
the Discretion order attribute is available during the Night 
Session, provided however, that during the Night Session, the 
Discretion order attribute may not be combined with the Pegging 
Order attribute, and further, that orders designated for the Night 
Session that combine the Discretion attribute with a Pegging 
attribute will be rejected).
    \60\ The ``Time-in-Force'' assigned to an Order means the period 
of time that the Nasdaq Market Center will hold the Order for 
potential execution. Participants specify an Order's Time-in-Force 
by designating a time at which the Order will become active and a 
time at which the Order will cease to be active. See Rule 4702.
    \61\ To effect this change, the Exchange proposes to amend Rule 
4703(a) as follows. Rule 4703(a) currently provides that available 
times for deactivating orders include ``a specific time identified 
by the Participant; provided, however, that an Order specifying an 
expire time beyond the current trading day will be cancelled at the 
end of the current trading day.'' The Exchange proposes to amend 
that provision to enhance clarity with respect to available times 
for deactivating orders as well as to address available times for 
deactivating orders during the proposed Night Session. Specifically, 
the Exchange proposes to amend this provision to provide that 
available times for deactivating orders include ``a specific time 
identified by the Participant; provided, however, that an Order 
specifying an expire time beyond 8:00 p.m. ET will be cancelled at 
the conclusion of the Day Sesson at 8:00 p.m. and that an Order 
entered during the Night Session specifying an expire time beyond 
4:00 a.m. ET will expire at the conclusion of the Night Session at 
4:00 a.m. ET.'' The Exchange also proposes certain conforming 
changes to delete from that same provision obsolete terms including 
``the current trading day'' and ``end of current trading day.'' See 
proposed Rule 4703(a). The Exchange further proposes to amend 
subparagraph (2) of Rule 4703 to delete the sentence that reads 
``[a]n Order that is designated to deactivate at 8:00 p.m. may be 
referred to as having a Time in Force of `System Hours Day' or 
`SDAY' '' and replace it with the following: ``[a]n Order with a 
Time in Force of `System Hours Day' or `SDAY' will deactivate at 
8:00 p.m., however, an Order with a Time in Force of `System Hours 
Day' or `SDAY' designated for participation in the Night Session 
will deactivate at 4:00 a.m.'' See proposed Rule 4703(a)(2). The 
Exchange believes these proposed changes are appropriate to provide 
greater clarity with respect to the operation of SDAY orders during 
the proposed Day Session as well as address how the SDAY TIF would 
operate during the Night Session as proposed.
---------------------------------------------------------------------------

    However, the Night Session will differ from Post-Market Hours and 
Pre-Market Hours trading in several respects. Below is a summary of the 
key functionality of the Night Session as it will be available at its 
launch date.
    <bullet> Connectivity: The Exchange will require market 
participants to use ports specifically designated for use during the 
Night Session.\62\ Market participants that have already purchased 
ports from the Exchange may continue using them to trade during the Day 
Session, but if participants wish to trade during the Night Session, 
then they will need to use a separate Night Session port to do so.\63\ 
The Exchange proposes this requirement to use Night Session ports 
because the Exchange will run a distinct instance of its Trading System 
during the Night Session, and ports used for Day Session will only be 
capable of connecting to the instance of the Trading System used to 
operate the Day Session. Day ports will be operational from 4:00 a.m. 
ET through 8:00 p.m. ET, and Night Session ports will be operational 
from 9:00 p.m. ET through the following day at 4:00 a.m. ET.\64\
---------------------------------------------------------------------------

    \62\ See proposed Rule 4702(a) (providing that, to trade in the 
Night Session, market participants will be required to use ports 
specifically designated for use during the Night Session, and that 
ports used for the Day Session will not connect market participants 
to trading systems for the Night Session). The Exchange further 
proposes to provide that the following protocols will be available 
during the Night Session: OUCH 5, Core FIX, and FIX. The Exchange 
proposes to offer OUCH 5, the latest version of the OUCH protocol, 
during the Night Session. For sessions other than the Night Session, 
the Exchange also offers legacy OUCH versions. The OUCH Order entry 
protocol is a proprietary protocol that allows subscribers to 
quickly enter orders into the System and receive executions. See 
Securities Exchange Act Release No. 95768 (September 14, 2022), 87 
FR 57534 (September 20, 2022).
    \63\ See proposed Rule 4702(a).
    \64\ To effect this change, the Exchange proposes to provide 
that Night Session ports will be operational from 9:00 p.m. ET 
through the following day at 4:00 a.m. ET in accordance with the 
definition of Night Session and that Day ports will be operational 
from 4:00 a.m. ET through 8:00 p.m. ET on Business Days. See 
proposed Rule 4702(a).
---------------------------------------------------------------------------

    <bullet> Times-in-Force: As noted above, the Exchange will employ 
the Time-in-Force Order Attribute during the Night Session as it does 
now during the Day Session, with two changes designed to reflect the 
Exchange's proposed hours of operations. First, the Exchange proposes 
to (1) amend Rule Equity 1, Section 1(a)(9) to update the definition of 
the term ``System Hours''--which is currently defined as the hours of 
4:00 a.m. ET through 8:00 p.m. ET--to reflect the Exchange's proposed 
hours of operation,\65\ and (2) amend Rule 4703(a) to provide that when 
an Order may be deactivated at the end of ``System Hours,'' the term 
``System Hours'' refers to the period from 9:00 p.m. ET to the 
following calendar day at 8:00 p.m. ET, in accordance with the 
definition of ``System Hours'' in Rule Equity 1, Section 1(a)(9).\66\
---------------------------------------------------------------------------

    \65\ See proposed Rule 1, Equity 1, Section 1(a)(9). As 
proposed, the term ``System Hours'' would mean the 23-hour time 
period beginning at 9:00 p.m. ET on one calendar day and ending at 
8:00 p.m. ET (or such earlier time as may be designated by Nasdaq on 
a day when Nasdaq closes early) on the next calendar day for the 
period from Sunday at 9:00 p.m. ET through Friday at 8:00 p.m. ET in 
accordance with definitions of Day Session (including the Pre-Market 
Hours, Regular Market Hours, Post-Market Hours) and Night Session. 
The Exchange further proposes to modify Equity 1, Section 1(a)(9) to 
delete the definitions of ``Market Hours,'' ``Pre-Market Hours'' and 
``Post-Market Hours,'' as the Exchange is proposing to define each 
such term separately elsewhere in Rule Equity 1, Section 1.
    \66\ See proposed Rule 4703(a). As proposed, the Exchange would 
provide that the available times for deactivating an order include, 
among others, at the end of System Hours, in accordance with the 
definition of ``System Hours'' in Rule Equity 1, Section 1(a)(9). 
See proposed Rule 4703(a).
---------------------------------------------------------------------------

    <bullet> Trading Halts: Consistent with the approved rules of 
another national securities exchange,\67\ the Exchange proposes to 
provide in Rule 4120(a)(10)(D) that during the Night Session, if the 
primary listing market, including Nasdaq when Nasdaq is the primary 
listing market, determines to halt trading, or delay commencement of 
trading, in one of its listed securities in accordance with such 
primary listing market's rules (e.g., with regard to material corporate 
actions with respect to a particular security (i.e., corporate actions 
that may affect a stock price, stock additions and subtractions, and 
similar actions) or material news announcements), the Exchange will 
halt trading, or delay the commencement of, trading (as applicable), in 
such security until trading resumes on the primary listing market for 
the security. Further, the Exchange proposes to provide that if trading 
in a security is halted by the primary listing market, including Nasdaq 
when Nasdaq is the primary listing market, before the commencement of 
the Night Session and continuing into the Night Session, or during the 
Night Session, the Exchange will halt trading in the security until 
trading resumes on the primary listing market for the security.\68\
---------------------------------------------------------------------------

    \67\ 24X Rule 11.15(c)(5).
    \68\ See proposed Rule 4120(a)(10)(D). Generally, regardless of 
trading session, when a halt has been declared on the primary 
listing market, the Exchange will also halt trading automatically in 
the subject security on the Exchange. Exchange staff will be 
available during the proposed Night Session in order to maintain a 
fair and orderly market, make any necessary rulings or take any 
action that may be necessary. Similarly, Exchange staff will be 
available if any action such as declaration of a halt in a Nasdaq 
primary symbol were necessary. Moreover, to the extent material 
corporate news is released during the Night Session and the primary 
listing market does not impose a halt, the requirements of proposed 
Rule Equity 2, Section 20 and proposed Rule Equity 2, Section 20(8) 
that disclosures be provided to customers relating to the risks 
associated with the exaggerated effect of news announcements and the 
additional risks of trading during the Night Session, respectively, 
will help ensure that market participants, including investors, are 
informed about the potential risks associated with trading during 
the Night Session. The Exchange also proposes a technical, non-
substantive conforming change to renumber subparagraphs (10)-(15) of 
current Rule 4120(a) as subparagraphs (11)-(16).

---------------------------------------------------------------------------

[[Page 20228]]

    <bullet> Clearly Erroneous Transactions: Consistent with the 
regulatory framework applied to national securities exchanges \69\ with 
respect to the use of clearly erroneous rules in extended hours 
sessions, the Exchange proposes to rely on its clearly erroneous rules 
\70\ during the Night Session. The Exchange believes this proposed 
change is appropriate because the use of clearly erroneous executions 
rules during the Night Session will help ensure that there is a 
consistent, market-wide approach across the extended hours trading 
sessions of all national securities exchanges.
---------------------------------------------------------------------------

    \69\ See, e.g., CboeBZX Rule 11.17; Nasdaq Equity 11, Rule 
11890; NYSE Arca Rule 7.10-E; 24X Rule 11.14.
    \70\ See proposed Rule 11890. To effect this change, the 
Exchange proposes to amend Equity 1, Rule 11890 (``Clearly Erroneous 
Transactions'') to incorporate the Night Session as appropriate 
throughout the various provisions in the rule. Specifically, the 
Exchange proposes to insert references to the Night Session in the 
following provisions: romanette (iii) of Rule 11890(a)(2)(A) (with 
respect to filing time periods); subparagraph (2) of Rule 11890(C), 
including the table under romanette (i) (with respect to eligibility 
for review) and romanettes (ii) and (iii) thereunder; subparagraph 
(3) of Rule 11890(a)(3)(D)(3) (with respect to trades on the Nasdaq 
Bond Exchange); and romanette (i) of Rule 11890(b) (with respect to 
procedures for reviewing transactions on Nasdaq's own motion).
---------------------------------------------------------------------------

    <bullet> Surveillance: During the Night Session, the Exchange will 
have a dedicated team to conduct real-time surveillance, process 
Clearly Erroneous filings, and as needed, implement trading halts. 
Real-time surveillance for the Night Session will be similar to real-
time surveillance in other sessions today. Real-time surveillance 
includes monitoring for unusual activity, the detection of potential 
manipulation and other market abuse, as well as coordination with 
Nasdaq departments and member firm representatives as necessary to 
monitor and or resolve unexpected matters. The Exchange will utilize 
the Nasdaq Market Surveillance system to electronically monitor and 
alert trading anomalies. The Clearly Erroneous process and trading 
halts for listed securities will be handled by the Exchange 
surveillance staff, similar to all other sessions, and in accordance 
with the rules applicable to Clearly Erroneous filings and Trading 
Halts.
    <bullet> Market Data: The Exchange proposes to disseminate the same 
market data information during the Night Session as are available 
during the Day Session.
    <bullet> Risk Disclosures: In accordance with Equity 2, Section 20, 
the Exchange proposes to supplement its current customer disclosures 
concerning risks associated with trading during Pre-Market Hours and 
Post-Market Hours to add six additional potential risks associated with 
trading during the Night Session based on the approved rules of 24X and 
NYSE Arca.\71\ As proposed, the Exchange would require that its members 
make certain disclosures to investors concerning risks associated with 
trading during Pre-Market Hours, Post-Market and the Night Session.\72\ 
These proposed disclosures will enhance transparency by warning 
customers that trading during these extended hours involves material 
trading risks, as outlined in the proposed rules.\73\
---------------------------------------------------------------------------

    \71\ See, e.g., 24X Approval Order, supra note 10; 24X Rule 3.21 
(``Customer Disclosures''); NYSE Arca Approval Order, supra note 10; 
NYSE Arca Rule 7.34-E(T) (``Trading Sessions'').
    \72\ See proposed Rule Equity 2, Section 20 (8)(A)-(F) 
(providing, in part, that trading during the Night Session may 
present risks, including (1) the risk of trading during hours in 
which the primary listing market may not be open, (2) the risk of 
trading during hours in which there may be limited or different 
regulatory protections, (3) the risk of having limited trading 
alternatives, (4) risks related to continuous trading, (5) the risk 
of trading during hours in which financial market infrastructure 
companies may be closed, (6) the risk of trading because the Night 
Session is novel and may presents additional unforeseen risks beyond 
those enumerated in the proposed rules, and (7) additional 
unforeseen risks in addition to those discussed above).
    \73\ See proposed Rule Equity 2, Section 20.
---------------------------------------------------------------------------

    <bullet> Equity Data Plans: Consistent with the approved rules of 
24X and NYSE Arca,\74\ the Exchange proposes to provide that the 
Exchange would not commence operation of the Night Session unless the 
Equity Data Plans (as proposed to be defined in Rule Equity 1, Section 
1(a)(16)) \75\ have established a mechanism to collect, consolidate, 
process and disseminate quotation and transaction information at all 
times during Extended Trading Hours that is equivalent to the mechanism 
established for Regular Market Hours, and (2) have provided the 
Exchange with notification that they are prepared to collect, 
consolidate, process and disseminate quotation and transaction 
information to accommodate the Night Session.\76\
---------------------------------------------------------------------------

    \74\ See 24X Rule 1.5(c); NYSE Arca Rule 7.34-E.
    \75\ As proposed, the term The term ``Equity Data Plans'' means 
the effective national market system plans that govern the 
collection, consolidation, processing and dissemination of equity 
market data for NMS stocks and oversee the exclusive securities 
information processors (``SIPs''), including (1) the Consolidated 
Tape Association Plan (``CTA Plan''), (2) the Consolidated Quotation 
Plan (``CQ Plan''), (3) the Joint Self-Regulatory Organization Plan 
Governing the Collection, Consolidation and Dissemination of 
Quotation and Transaction Information for Nasdaq- Listed Securities 
Traded on Exchanges on an Unlisted Trading Privileges Basis (``UTP 
Plan''), (4) the CT Plan established by the Limited Liability 
Company Agreement of CT Plan LLC, and (5) any successor thereto to 
the named Plans. See proposed Rule Equity 1, Section 1(a)(16).
    \76\ Also consistent with the approved rules of 24X and NYSE 
Arca, the Exchange further proposes to provide that, prior to 
commencing operation during the Night Session, the Exchange will 
file a proposed rule change pursuant to Section 19(b) of the 
Exchange Act and the rules thereunder to amend its rules confirming 
that the Exchange is able to comply with its obligations under the 
Exchange Act and the rules thereunder during the Night Session and 
that such Equity Data Plans are prepared to collect, consolidate, 
process and disseminate quotation and transaction information at all 
times during the Night Session (``Night Session Proposed Rule 
Change''). If the Night Session Proposed Rule Change is not filed 
within 18 months of the Commission's approval of this proposed rule 
change, the Exchange will promptly file a proposed rule change to 
remove the rules that apply to the Night Session. The Exchange will 
submit all quotes and trades that are generated in the Night Session 
to the consolidated quote and trade systems maintained by the SIPs 
for public dissemination. Accordingly, once the proposed Night 
Session is operative, quotes and trades will be made available to 
the investing public in the same manner that quotes and trades are 
currently made available. See, e.g., proposed Rule Equity 1, Section 
1(a)(19); 24X Rule 1.5(c); NYSE Arca Rule 7.34-E.
---------------------------------------------------------------------------

Transition From Night to Day Session
    The following describes proposed procedures for the Exchange to 
transition from a Night Session to a Day Session at 4:00 a.m. ET each 
weekday. At the conclusion of the Night Session at 4:00 a.m. ET, all 
orders outstanding on the Nasdaq Book as of 4:00 a.m. ET will be 
canceled.\77\ The Exchange currently begins accepting new orders for 
the Pre-Market Session at 4:00 a.m. ET,\78\ and, as proposed, this 
would remain unchanged.
---------------------------------------------------------------------------

    \77\ To effect this change, the Exchange proposes to provide in 
proposed Rule 4120(a)(10)(C) that at the conclusion of the Night 
Session at 4:00 a.m. ET, all orders outstanding in the Nasdaq Book 
as of 4:00 a.m. ET shall be cancelled. See proposed Rule 
4120(a)(10)(C).
    \78\ See Rule 4752(b).
---------------------------------------------------------------------------

Weekday 8:00-9:00 p.m. ET Trading Pause
    As proposed, upon conclusion of the Day Session on each weekday, at 
8:00 p.m. ET, trading on the Exchange will pause for one hour.\79\ It 
will resume with commencement of the Night Session at 9:00 p.m. ET.\80\ 
All orders

[[Page 20229]]

outstanding on the Nasdaq Book as of 8:00 p.m. ET will be canceled.\81\ 
The Exchange will begin accepting new orders at 9:00 p.m., Sunday 
through Thursday and will trade thereafter throughout the Night 
Session.\82\ At the conclusion of the Night Session at 4:00 a.m. ET, 
all orders outstanding in the Nasdaq Book as of 4:00 a.m. ET will be 
cancelled.\83\
---------------------------------------------------------------------------

    \79\ See proposed Rule 4120(a)(10). To effect this change, the 
Exchange proposes to provide in proposed Rule 4120(a)(10) that the 
Exchange shall halt trading at the conclusion of the Day Session at 
8:00 p.m. ET and resume trading with the commencement of the Night 
Session at 9:00 p.m. ET, on Monday, Tuesday, Wednesday and Thursday, 
in accordance with Rule Equity 1, Sections 1(a)(18)-(19) of these 
rules. As further proposed, weekday trading would commence with a 
Night Session beginning at 9:00 p.m. ET, on Sunday. See proposed 
Rule 4120(a)(10).
    \80\ See proposed Rule 4120(a)10. Consistent with the approved 
rules of another national security exchange, and specifically 24X 
Rule 11.15(c)(4), the Exchange proposes to provide that the Exchange 
may pause trading during the Night Session at such other times as 
the Exchange in the exercise of its regulatory functions may 
determine is appropriate, and that the Exchange will announce in 
advance when such trading will pause and when it will resume 
pursuant to this paragraph. See, e.g., proposed Rule 4120(a)(10)(A); 
24X Rule 11.15(c)(4).
    \81\ See proposed Rule 4120(a)(10)(B). To effect this change, 
the Exchange proposes to provide in proposed Rule 4120(a)(10)(B) 
that orders outstanding on the Nasdaq Book as of 8:00 p.m. ET shall 
be cancelled. See id.
    \82\ See proposed Rule 4120(a)(10)(C). To effect this change, 
the Exchange proposes to provide that the Exchange will begin 
accepting orders for the Night Session at 9:00 p.m. ET in accordance 
with Rule 4756 and will trade thereafter throughout the Night 
Session. As discussed above, the Exchange is also proposing to 
provide in Rule 4756(a)(3) that Orders for the Night Session may be 
entered into the System (or previously entered Orders cancelled or 
modified) from 9 p.m. until 4:00 a.m. ET in accordance with the 
hours of operation for the Night Session. See proposed Rule 
4756(a)(3).
    \83\ See proposed Rule 4120(a)(10)(C) (proposing to provide, in 
part, that at the conclusion of the Night Session at 4:00 a.m. ET, 
all orders outstanding in the Nasdaq Book as of 4:00 a.m. ET shall 
be cancelled).
---------------------------------------------------------------------------

    The trading pause will mitigate systemic risk to the markets and 
promote resiliency by providing time for both the Exchange and market 
participants to conduct maintenance and testing. During the pause, for 
example, the Exchange will shift its operations to a second instance of 
its System that will run the Night Session.
    Finally, the trading pause will allow the Exchange to process, or 
to begin processing any corporate actions that may be pending for the 
next trading day, including stock splits, dividends, name changes, and 
distributions. The Exchange notes that certain corporate actions will 
likely require halts beyond the trading pause. For example, dividends 
must be paid on particular calendar days, which will not, going 
forward, always coincide with the commencement of new trading days on 
Nasdaq at 9:00p.m. ET. Accordingly, Nasdaq will likely need to halt 
trading in such securities until sometime during the next calendar 
date.
Related Proposed Rule Changes
    As discussed above, the Exchange proposes to trade NMS stocks and 
ETPs on a 23/5 basis. To effect this change with respect to certain 
ETPs, the Exchange proposes to amend certain rules under the Nasdaq 
5700 Series as follows. The Exchange proposes to provide that, in 
addition to the Regular Market Hours and the Pre-and Post-Market Hours, 
as it does today, Nasdaq may designate the following for trading during 
the Night Session: Exchange Traded Fund Shares,\84\ Portfolio 
Depositary Receipts listed pursuant to Rules 5705(a)(4) and (5),\85\ 
and Index Fund Shares.\86\ The Exchange believes this proposed change 
would remove impediments to and perfect the mechanism of a free and 
open market, and in general, protect investors and the public interest 
because the Exchange has rules in place to facilitate the trading of 
such ETPs during all trading sessions and may designate such ETPs for 
trading during all extended hours sessions, of which the proposed Night 
Session would constitute part.
---------------------------------------------------------------------------

    \84\ See proposed Rule 5704(b)(1)(C). To effect this change, the 
Exchange proposes to insert the words ``or Night Session, as such 
terms are defined in Rule 4120'' immediately following the 
description of the Pre- and Post-Market Hours sessions in Rule 
5704(b)(1)(C). The Exchange also proposes to make related conforming 
changes to remove obsolete language describing the current trading 
sessions and substitute therefor for the proposed terms for each 
such trading session. See proposed Rule 5704(b)(1)(C).
    \85\ See proposed Rule 5705(a)(7). To effect this change, the 
Exchange proposes to insert the words ``or Night Session, as such 
terms are defined in Rule 4120'' immediately following the 
description of the Pre- and Post-Market Hours sessions in Rule 
5705(a)(7) and make related conforming changes to remove obsolete 
language describing the current trading sessions and substitute 
therefor for the proposed terms for each such trading session. See 
proposed Rule 5705(a)(7).
    \86\ See proposed Rule 5705(b)(7). To effect this change, the 
Exchange proposes to insert the words ``or Night Session, as such 
terms are defined in Rule 4120'' immediately following the 
description of the Pre- and Post-Market Hours sessions in Rule 
5705(b)(7) and make related conforming changes to remove obsolete 
language describing the current trading sessions and substitute 
therefor for the proposed terms for each such trading session. See 
proposed Rule 5705(b)(7).
---------------------------------------------------------------------------

Impact on Exchange Fees
    The Exchange will address any impact of the rule proposal on its 
schedule of credits and fees, and its incentive programs, in a 
subsequent rule filing.
Clarifying, Conforming and Other Non-Substantive Changes
    The Exchange proposes to amend current Equity 1, Section 1 to add 
three clarifying definitions. First, the Exchange proposes to define 
``Equity Data Plans'' to mean the effective national market system 
plans that govern the collection, consolidation, processing and 
dissemination of equity market data for NMS stocks and oversee the 
exclusive securities information processors (``SIPs''), including (1) 
the Consolidated Tape Association Plan (``CTA Plan''), (2) the 
Consolidated Quotation Plan (``CQ Plan''), (3) the Joint Self-
Regulatory Organization Plan Governing the Collection, Consolidation 
and Dissemination of Quotation and Transaction Information for Nasdaq- 
Listed Securities Traded on Exchanges on an Unlisted Trading Privileges 
Basis (``UTP Plan''), (4) the CT Plan established by the Limited 
Liability Company Agreement of CT Plan LLC, and (5) any successor 
thereto to the named Plans.\87\ Second, the Exchange proposes to define 
``Business Day'' to mean any Monday, Tuesday, Wednesday, Thursday or 
Friday other than any of the following U.S. holidays if they are 
celebrated on a Monday, Tuesday, Wednesday, Thursday or Friday: New 
Year's Day, Martin Luther King Jr. Day, Presidents' Day, Good Friday, 
Memorial Day, Juneteenth National Independence Day, Independence Day, 
Labor Day, Thanksgiving Day and Christmas Day ET, or such other U.S. 
holiday(s) as published by the Exchange from time to time.\88\ Finally, 
the Exchange proposes to define ``Extended Hours'' to mean that, unless 
otherwise specified in Exchange rules, the term means the hours outside 
of Regular Market Hours and specifically comprising the hours during 
which Pre-Market Hours, Post-Market Hours, and Night Session are in 
operation.\89\
---------------------------------------------------------------------------

    \87\ See proposed Rule Equity 1, Section 1(a)(16).
    \88\ See proposed Rule Equity 1, Section 1(a)(17).
    \89\ See proposed Equity 1, Section 1(a)(23).
---------------------------------------------------------------------------

    The Exchange also proposes the following conforming, non-
substantive changes.
    <bullet> The Exchange proposes to amend the following rules to 
replace references to ``Market Hours,'' ``regular market hours,'' and 
similar references used to designate the trading session operating from 
9:30 a.m. ET through 4:00 p.m. ET with the proposed term ``Regular 
Market Hours,'' and make related conforming changes: Rule Equity 1, 
Section 1(a)(9); Rule Equity 2, Section 20; and Rules 4120, 4702, 
4703,\90\ 4752, 4753, 4754,\91\

[[Page 20230]]

IM-5250-1,\92\ 5704, 5705, 5710, 5711, 5713, 5745, 5760, 5810(b), 5840, 
and 11890.
---------------------------------------------------------------------------

    \90\ The Exchange proposes one additional non-substantive change 
to Rule 4703(l) to correct a typographical error. Rule 4703(l) 
incorrectly refers to Opening Imbalance Only Orders as ``OI Orders'' 
in one instance and ``IO Orders'' in another. The Exchange proposes 
to amend that subparagraph of Rule 4703 to revise such references as 
necessary to correctly reflect the defined term for such orders: 
``OIO Orders.'' See Rule 4702(a)(10)(A) (defining the term ``Opening 
Imbalance Only Order'' or ``OIO Order''). The Exchange believes this 
administrative non-substantive change is appropriate to enhance 
clarity and thus facilitate the use of and compliance with the 
Exchange's rules.
    \91\ The Exchange proposes an additional non-substantive change 
to Rule 4754(b) to delete the ``S'' from ``EST'' and thus use the 
acronym ``ET'' as defined in Rule Equity 1, Section 1(a)(8). See 
Rule Equity 1, Section 1(a)(8) (providing that the term ``ET'' means 
Eastern Standard Time or Eastern Daylight Time, as applicable).
    \92\ The Exchange further proposes a non-substantive, clarifying 
change to Rule IM-5250-1. Specifically, the Exchange proposes to 
delete the term ``market hours'' from the second paragraph of the 
section titled ``Notification to Nasdaq MarketWatch Department and 
replace it with the more precise time range ``7:00 a.m. to 8:00 
p.m.'' The Exchange believes this clarifying change is appropriate 
to align this paragraph with the preceding one which requires that 
material news reported outside the hours of 7:00 a.m. to 8:00 p.m. 
be disclosed prior to 6:50 a.m. under the rule.
---------------------------------------------------------------------------

    <bullet> The Exchange proposes to amend the following rules to 
replace references to terms such as ``Pre-Market Session,'' ``Early 
Market Hours,'' and similar terms used to designate the pre-market 
trading session operating from 4:00 a.m. ET through 9:30 a.m. ET with 
the defined term ``Pre-Market Hours'' and make related conforming 
changes: Rule Equity 2, Section 20, and Rules 4120, 4702, 4703, 4753, 
5704, 5705, and 11890.
    <bullet> The Exchange proposes to amend the following rules to 
replace references to terms such as ``Post-Market Session,'' ``Extended 
Market Hours,'' and similar terms used to designate the trading session 
operating from 4:00 p.m. ET through 8:00 p.m. ET, with the term ``Post-
Market Hours'' and make related conforming changes: Rule Equity 2, 
Section 20, and Rules 4120, 4702, 4703, 4753, 4755,\93\ 5704, 5705, and 
11890.
---------------------------------------------------------------------------

    \93\ In this Amendment No.2 to the proposal, the Exchange is 
proposing one non-substantive technical change to Rule 4755 to 
update the cross reference to the definition of ``Post-Market 
Hours.'' Specifically, the Exchange proposes to delete the reference 
to Rule Equity 1, Section 1(a)(9) and replace it with a reference to 
proposed Rule Equity 1, Section 1(a)(21) (proposing to define the 
term ``Post-Market Hours''). The Exchange believes this proposed 
non-substantive change is appropriate to accurately cross reference 
the definition of ``Post-Market Hours'' as proposed and thus 
facilitate the understanding and use of the Exchange's rules. The 
Exchange is proposing no other changes to Rule 4755.
---------------------------------------------------------------------------

    <bullet> The Exchange proposes to amend the following rules to 
replace references to ``extended hours'' with the term ``Extended 
Hours,'' as defined in Rule 1, Equity Section 1(a)(23): Rule Equity 2, 
Section 20, and Rule 4703.
    <bullet> The Exchange would also make certain conforming changes as 
follows. First, the Exchange proposes to delete the obsolete reference 
to ``4:00 a.m. to 8 p.m. Eastern Time on each business day'' in Rule 
Equity 2, Section 8, and substitute therefor the term ``System Hours,'' 
\94\ so as to update and align this rule with the proposed hours of 
operation for the Exchange. The Exchange proposes to make non-
substantive changes to Rule 4120 \95\ as follows. The Exchange proposes 
to amend subparagraph (B) of Rule 4120(b)(4) to (1) to conform the 
current terms ``Pre-Market Session,'' ``Post-Market Session,'' and 
``Market Hours'' to the proposed terms ``Pre-Market Hours,'' ``Post-
Market Hours,'' and ``Regular Market Hours,'' as proposed Rule Equity 
1, Sections 1(a)(20)-(22), respectively.\96\ The Exchange further 
proposes to add in new subparagraphs (F)-(G) of Rule 4120(b)(4) that 
the terms ``Day Session'' and ``Night Session'' shall have the same 
meaning as defined in Rule Equity 1, Sections 1(a)(18) and (19), 
respectively. Consistent with how the Exchange operates during the 
Post-Market Hours, the Exchange also proposes to provide in Rule 
4120(a)(3)(A), that if an applicable Required Value \97\ continues not 
to be calculated or widely disseminated after the close of the Regular 
Market Hours, Nasdaq may trade a Derivative Securities Product \98\ 
during the Night Session only if the listing market traded the 
Derivative Securities Product until the close of its regular trading 
session without a halt.\99\
---------------------------------------------------------------------------

    \94\ See, e.g., proposed Rule Equity 2, Section 8; proposed Rule 
Equity 1, Section 1(a)(9) (defining the term ``System Hours''). To 
effect this change, the Exchange proposes to delete, from Rule 
Equity 2, Section 8, the words ``from 4:00 a.m. to 8:00 p.m. 
Eastern. Time on each business day'' and substitute therefor the 
words ``during System Hours.'' See proposed Rule Equity 2, Section 
8.
    \95\ In Amendment No. 2 to the proposed rule change, the 
Exchange updates Exhibit 5 to the proposal to reflect changes to 
Rule 4120 that were adopted after the date of the initial filing. 
See, e.g., Notice, supra note 3; Exchange Rule 4120.
    \96\ See proposed Rule 4120(b)(4)(B)-(D). The Exchange notes 
that for purposes of Rule 4120 and in connection with the trading of 
certain derivative securities products as provided thereunder, the 
definitions of ``Post-Market Hours'' and ``Regular Market Hours'' 
differ from those proposed in Equity 1, Section 1 only in that (1) 
``Regular Market Hours,'' as defined in Rule 4120, run until ``4:00 
p.m. or 4:15 p.m.'' on Business Days (rather than until 4:00 p.m. on 
Business Days as provided in proposed Rule Equity 1 Section 
1(a)(22)) and (2) ``Post-Market Hours,'' as defined in Rule 4120 
begin at ``4:00 p.m. or 4:15 p.m.'' on Business Days (rather than at 
4:00 p.m. on Business Days, as proposed in Rule Equity 1, Section 
1(a)(21)). The Exchange is not proposing to modify such definitions 
under Rule 4120(b).
    \97\ ``Required Value'' means (i) the value of any index or any 
commodity-related value underlying a Derivative Securities Product, 
(ii) the indicative optimized portfolio value, intraday indicative 
value, or other comparable estimate of the value of a share of a 
Derivative Securities Product updated regularly during the trading 
day, (iii) a net asset value in the case of a Derivative Securities 
Product for which a net asset value is disseminated, and (iv) a 
Disclosed Portfolio in the case of a Derivative Securities Product 
that is a series of Managed Fund Shares, as defined in Rule 5735, or 
Managed Trust Securities, as defined in Rule 5711(j), and a 
Composition File in the case of a Derivative Securities Product that 
is a series of NextShares, as defined in Rule 5745. See Rule 
4120(b)(4)(E).
    \98\ See proposed Rule 4120(b)(3)(A). ``Derivative Securities 
Product'' means a series of Exchange Traded Fund Shares, Portfolio 
Depository Receipts, Index Fund Shares, Managed Fund Shares, 
NextShares, Trust Issued Receipts, or Proxy Portfolio Shares (as 
defined in Rules 5704, 5705, 5735, 5745, 5720, and 5750 
respectively), a series of Commodity-Related Securities (as defined 
in Equity 10, Section 8), securities representing interests in unit 
investment trusts or investment companies, Index- Linked 
Exchangeable Notes, Equity Gold Shares, Trust Certificates, 
Commodity-Based Trust Shares, Currency Trust Shares, Commodity Index 
Trust Shares, Commodity Futures Trust Shares, Partnership Units, 
Trust Units, Managed Trust Securities, or Currency Warrants (as 
defined in Rule 5711(a)--(k)), or any other UTP Derivative Security 
(as defined in Rule 5740). See Rule 4120(b)(4)(A).
    \99\ To effect this change, the Exchange proposes to amend Rule 
4120(b)(3)(A) to insert, immediately after ``Post-Market Session,'' 
the words ``and during the Night Session.'' The Exchange also 
proposes a non-substantive to conform the term ``Post Market 
Session'' to the proposed term ``Post-Market Hours'' by deleting the 
word ``Session'' and substituting therefor the word ``Hours.'' As 
described below, the Exchange is proposing non-substantive changes 
to conform terms ``Pre-Market Session,'' Post-Market Session, and 
``Market Hours'' in each instance such terms are used within Rule 
4120 with the proposed terms ``Pre-Market Hours,'' ``Post-Market 
Hours,'' and ``Regular Market Hours,'' respectively. The Exchange 
believes that establishing uniform names for its trading sessions, 
as proposed, is appropriate because consolidating the varying terms 
for each such session into one defined and uniform term for each 
such session would facilitate the understanding of and compliance 
with the Exchange's rules. See, e.g., proposed Rule 4120; proposed 
Rule Equity 1, Section 1(a)(20)-(22).
---------------------------------------------------------------------------

    Finally, the Exchange proposes a technical, non-substantive 
conforming change to renumber subparagraphs (10)-(15) of Rule 4120(a) 
as subparagraphs (11)-(16).

II. Statutory Basis

    The Exchange believes that its proposal is consistent with Section 
6(b) of the Act,\100\ in general, and furthers the objectives of 
Section 6(b)(5) of the Act,\101\ in particular, in that it is designed 
to promote just and equitable principles of trade, to remove 
impediments to and perfect the mechanism of a free and open market and 
a national market system, and, in general to protect investors and the 
public interest.
---------------------------------------------------------------------------

    \100\ 15 U.S.C. 78f(b).
    \101\ 15 U.S.C. 78f(b)(5).
---------------------------------------------------------------------------

    It is consistent with the Act to permit members of the Exchange to 
trade securities on an extended basis, for 23 hours per day, 5 days per 
week. As explained above, investors increasingly trade securities, 
along with digital assets, on a global basis. Investors located outside 
of the United States in places like Asia presently cannot trade on 
Nasdaq during what constitutes their regular trading hours, as the 
Exchange is closed during that period. Even among U.S.-based investors, 
demand is growing for exchanges to expand their market hours to 
accommodate overnight trading. Accordingly, investors seeking

[[Page 20231]]

access to U.S. equities and ETP markets during overnight and weekend 
hours must resort to trading on a handful of ATSs that offer round-the-
clock trading. Nasdaq's proposal will enable Nasdaq to serve these 
investors and to compete with ATSs, foreign securities markets. and 
other markets for their order flow. It will also enable the Exchange to 
compete with new and incumbent exchanges which the SEC has approved to 
trade overnight in a similar manner.
    The Exchange's proposal to operate on an extended hours basis is 
largely based on Nasdaq's longstanding rules for extended hours 
trading, as well as the approved rules of other national securities 
exchanges also seeking to operate on a 23/5 basis. As proposed, these 
rules are designed to address potential differences in trading compared 
to regular trading hours, as well as to enhance transparency and 
investor protections. For example, the Exchange is proposing to 
supplement the existing required customer disclosures to require the 
disclosure of six additional potential risks associated with trading 
during extended hours, including the proposed Night Session. Such 
disclosures notify investors of potential risks and allow them to 
evaluate whether to trade during extended hours. The Exchange would 
also implement measures to safeguard against trade executions that are 
clearly erroneous while it works to build industry-wide consensus on 
proposals for establishing uniform after-hours volatility moderators. 
The Exchange believes that requiring the use of ports specifically 
designated for use during the Night Session is appropriate because the 
Night Session operates on a technically distinct trading system from 
the Day Session. As a result, Day Session ports cannot connect to, or 
interact with, the Night Session trading system. This approach reflects 
the technical and functional separation of the two systems and ensures 
that Night Session activity occurs in a manner consistent with the 
Act's goals of ensuring market integrity, investor protection, and fair 
and orderly trading. Nasdaq would also address corporate actions, 
conduct real-time surveillance, and implement trading halts consistent 
with its proposed rules. Finally, trading overnight will be transparent 
because Nasdaq will not commence operations of the proposed extended 
hours until the Equity Data Plans are prepared to collect, consolidate, 
process, and disseminate quotation and transaction information at all 
times during the Night Session. The proposed rules will also foster 
competition by introducing another trading venue during the overnight 
hours, as at least two other exchanges have obtained Commission 
approval for operating on an extended hours basis.
    In addition to increasing investor access to the Exchange, the 
proposal also stands to promote capital formation and facilitate 
portfolio management.
    Finally, the Exchange believes that the proposed conforming and 
other non-substantive changes would remove impediments to and perfect 
the mechanism of a free and open market by reducing potential investor 
and market participant confusion thereby ensuring that investors and 
market participants can more easily navigate, understand and comply 
with the Exchange's rules.

B. Self-Regulatory Organization's Statement on Burden on Competition

    The Exchange does not believe that the proposed rule changes will 
impose any burden on competition not necessary or appropriate in 
furtherance of the purposes of the Act. The Exchange's proposal to 
expand its trading hours to 23 hours a day, 5 days per week are neither 
intended to nor will they adversely impact competition. If anything, 
the Exchange expects that the proposed changes will promote competition 
by providing for the Nasdaq Stock Market to accommodate the growing 
demand to trade equity securities during overnight hours when the 
market is presently closed. Unaffiliated exchanges remain free to 
compete by offering extended hours trading of similar duration. The 
Exchange believes that requiring the use of designated ports for the 
Night Session will not impose a burden on competition that is not 
necessary or appropriate in furtherance of the purposes of the Act. The 
requirement for separate ports merely reflects the technical and 
functional separation of the two systems and ensures that Night Session 
activity occurs in a manner consistent with the Act's goals of ensuring 
market integrity, investor protection, and fair and orderly trading.
    The Exchange operates in a highly competitive market in which 
market Participants can readily choose between competing venues if they 
deem participation in the Exchange's market to no longer be desirable 
or if they do not wish to trade during the new Night Session. In such 
an environment, the Exchange must carefully consider the impact that 
any change it proposes may have on market participants, understanding 
that it will likely lose participants to the extent a change is viewed 
as unfavorable by them. Because competitors are free to modify the 
functionality and structure of their markets, including by availing 
themselves of the same capabilities that are being developed to trade 
securities and ETPs on a 23/5 basis, the Exchange believes that the 
degree to which its proposal imposes any burden on competition is 
limited. Last, to the extent the proposed change is successful in 
attracting additional market participants or additional activity by 
existing participants, the Exchange also believes that the proposed 
change will promote competition among trading venues by making the 
Exchange a more attractive trading venue.

C. Self-Regulatory Organization's Statement on Comments on the Proposed 
Rule Change Received From Members, Participants, or Others

    The Exchange has neither solicited nor received written comments on 
the proposed rule change. The Exchange has, however, responded to 
comments received in response to the Notice.

III. Discussion and Commission Findings

    The Commission finds that the Amended Proposal is consistent with 
the requirements of the Exchange Act and the rules and regulations 
thereunder applicable to a national securities exchange.\102\ In 
particular, the Commission finds that the Amended Proposal is 
consistent with Section 6(b)(5) of the Exchange Act,\103\ which 
requires, among other things, that the rules of a national securities 
exchange be designed to prevent fraudulent and manipulative acts and 
practices, to promote just and equitable principles of trade, to remove 
impediments to and perfect the mechanism of a free and open market and 
a national market system, and, in general, to protect investors and the 
public interest; and are not designed to permit unfair discrimination 
between customers, issuers, brokers, or dealers.
---------------------------------------------------------------------------

    \102\ 15 U.S.C. 78f(b). In approving this proposed rule change, 
the Commission has considered the proposed rule change's impact on 
efficiency, competition, and capital formation. See 15 U.S.C. 
78c(f).
    \103\ 15 U.S.C. 78f(b)(5).
---------------------------------------------------------------------------

    Specifically, Nasdaq proposes to extend its hours of operation to 
include a Night Session, which is modeled on the Exchange's existing 
rules that govern Pre-Market Hours and Post-Market Hours sessions, as 
well as rules approved by the Commission for similar sessions on other 
national securities exchanges.\104\ As proposed, Nasdaq will

[[Page 20232]]

have two sessions--a Day Session and a Night Session--for trading on 
Business Days. The Day Session will consist of three individual trading 
sessions: Pre-Market Hours beginning at 4:00 a.m. and continuing until 
9:30 a.m.; Regular Market Hours beginning at 9:30 a.m. and continuing 
until 4:00 p.m. and Post-Market Hours beginning at 4:00 p.m. and 
continuing until 8:00 p.m. The Night Session will begin at 9:00 p.m. on 
one calendar day and continue until 4:00 a.m. on the next calendar day, 
so long as the next calendar day is a Business Day. The Night Session 
will begin on Sunday evenings at 9:00 p.m. and a Night Session will be 
held Monday through Thursday. As described by the Exchange, the Night 
Session will operate in a manner that is consistent with the Pre-Market 
Hours and Post-Market Hours sessions but will require additional 
customer disclosures about the potential risks of trading during the 
Night Session and the use of a dedicated port.
---------------------------------------------------------------------------

    \104\ See 24X Approval Order and NYSE Arca Approval Order, supra 
note 10.
---------------------------------------------------------------------------

    Further, as discussed below, the Exchange will not commence 
operation of the Night Session prior to a filing of a proposed rule 
change to confirm its and the Equity Data Plans' readiness. 
Specifically, Nasdaq Equity 1, Section 1(a)(19) requires the Exchange 
to file a proposed rule change, pursuant to Section 19(b) of the 
Exchange Act and the rules thereunder, to amend its rules confirming 
that the Exchange is able to comply with its obligations under the 
Exchange Act during the Night Session and that the Equity Data Plans 
are prepared to collect, consolidate, process and disseminate quotation 
and transaction information during that time period.
    Accordingly, the Amended Proposal is designed to prevent fraudulent 
and manipulative acts and practices, promote just and equitable 
principles of trade, foster cooperation and coordination with persons 
engaged in regulating, clearing, settling, processing information with 
respect to and facilitating transactions in NMS stocks, and perfect the 
mechanism of a free and open market and a national market system. 
Moreover, the Amended Proposal will foster competition by introducing 
another trading venue during the overnight hours. As amended, the 
Exchange's rules for the Night Session are designed to increase 
transparency and enhance customer risk disclosures such that the 
Exchange will operate the Night Session in a manner that is consistent 
with the regulatory framework of the extended hours sessions of other 
national securities exchanges.

A. General Comments on Extended Hours Trading

    The Commission received comment letters on the proposal and a 
response from the Exchange.\105\ Several commenters supported the 
proposal.\106\ One commenter expressed support for the proposal with 
recommendations, including that Nasdaq submit specific ``implementation 
dates for updated trading halts and volatility mechanism rules.'' \107\ 
Nasdaq responded that its proposed rules governing trading halts and 
volatility mechanisms during the Night Session are substantively 
identical to the approved rules of another national securities exchange 
operating extended hours sessions citing rules of 24X and NYSE 
Arca.\108\ This commenter also stated that Nasdaq should provide 
investor education on 23-hour trading.\109\ Another commenter that 
supported the Amended Proposal stated that the Commission should 
approve the Amended Proposal.\110\
---------------------------------------------------------------------------

    \105\ See supra note 4.
    \106\ See, e.g., Letter from Alexander Kralev, dated Feb. 12, 
2026 (``Kralev Letter''); Letter from Katie Kolchin, CFA Managing 
Director, Head of Equity & options Market Structure, and Gerald 
O'Hara, Vice President, Assistant General Counsel, SIFMA, dated Mar. 
19, 2026 (``SIFMA Letter''). One commenter that supported the 
proposal also suggested that Nasdaq change its hours of the Day 
Session and the Closing Cross to occur earlier in time. See Kralev 
Letter. Nasdaq responded that it had not proposed to modify the time 
for the Closing Cross and that the time would remain unchanged at 
4:00 p.m. ET. See Nasdaq Letter at 4.
    \107\ See Letter from Kara Maniscalco, dated Jan. 29, 2026 
(``Maniscalco Letter'') at 6.
    \108\ See Nasdaq Letter at 2.
    \109\ See Maniscalco Letter at 6.
    \110\ See SIFMA Letter at 1. This commenter also raised 
``additional questions and issues for broader consideration outside 
of the context of a single exchange rule filing,'' including SIP 
availability, harmonization of trade date, adoption of a one-hour 
trading pause, and coordination of corporate actions. See SIFMA 
Letter. As stated below, the Commission is monitoring the 
developments of extended trading hours.
---------------------------------------------------------------------------

    Several other commenters opposed the proposal to extend the 
Exchange's trading hours.\111\ One commenter stated that the Commission 
had not given sufficient consideration to the issues because the 
Commission had not issued requests for information, published concept 
releases or held roundtables before setting forth its views on 
overnight trading.\112\ Nasdaq stated that the issues related to 
extended hour trading generally, including those raised by commenters, 
have been considered and addressed by the Commission.\113\ The 
Commission has previously sought public comment on the proposed rules 
of a national securities exchange related to overnight trading, 
received substantive input from a variety of commenters, and considered 
the relevant issues prior to taking action.\114\ Further, as the 
Commission has stated, the overnight trading of NMS stocks is not novel 
as it currently occurs on the over-the-counter market on ATSs (i.e., 
during the time period proposed by Nasdaq).\115\
---------------------------------------------------------------------------

    \111\ See Letter from Kevin Bell, dated Dec. 18, 2025 (``Bell 
Letter''); Letter from Anonymous, dated Jan. 14, 2026 (``Anonymous 
Letter''); Letter from Francesco Terranova, dated Jan. 27, 2026 
(``Terranova Letter''); Letter from Benjamin L. Schiffrin, Director 
of Securities Policy, Better Markets, Inc., dated Feb. 3, 2026 
(``Better Markets Letter''); and Letter from Jonathon Patterson,

---------------------------------------------------------------------------

    One commenter pointed out that some market participants remain 
critical of the expansion of trading hours for national securities 
exchanges and warned of the potential systemic risks (thin liquidity, 
volatility, gamification, and harm to retail investors) related to 
around-the-clock trading.\116\ Other commenters questioned the benefits 
of 24-hour trading,\117\ warned of fragmented liquidity and 
volatility,\118\ warned of structural risks and concentration of power 
in low volume periods,\119\ and recommended disapproval.\120\ Another 
commenter stated that retail investors are in early stages of 
developing disciplined risk management practices and that introducing 
continuous trading could undermine gains.\121\ One commenter also 
stated that the times when trading does not occur provides a ``vital 
cooling-off period'' that allows the market to digest news, earnings 
and global events.\122\

    \121\ See Patterson Letter.
    \122\ See Terranova Letter.
---------------------------------------------------------------------------

    The Exchange responded that the concerns raised by the comments 
with respect to extended hours trading, such as risks to investors, 
market stability, and lack of liquidity, have been considered and 
addressed by the Commission in approving similar proposals from other 
exchanges.\123\ The Exchange stated that the proposal is based on 
established and Commission -approved rules of other exchanges that 
offer comparable extended hours trading.\124\ The Exchange further 
stated that the Commission has allowed retail

[[Page 20233]]

participation in extended hours trading with appropriate disclosures, 
and that the Exchange's proposed mandatory customer disclosures are 
substantively identical to the approved rules of another exchange.\125\
---------------------------------------------------------------------------

    \123\ See Nasdaq Letter at 4.
    \124\ See id.
    \125\ See id. at 2-3.
---------------------------------------------------------------------------

    One commenter stated that the Commission could consider more 
limited and structured extensions of existing trading hours with full 
regulatory protections, circuit breakers and reporting requirements or 
the Commission could consider limiting the securities available during 
extended trading hours, such as highly liquid large-cap stocks.\126\ 
The Exchange stated that it will operate within a regulatory framework 
consistent with that applied to extended hours sessions of other 
national securities exchanges, and that ``the existing safeguards 
applicable to premarket and postmarket sessions, including operational 
safeguards, consolidated last sale and quotation information, enhanced 
customer risk disclosures for afterhours trading, and market 
surveillance capabilities'' would also apply to the Night Session.\127\ 
As discussed, Nasdaq's proposal is substantively identical to the 
approved rules of another national securities exchange and to Nasdaq 
rules for the Pre-Market Hours and Post-Market Hours.
---------------------------------------------------------------------------

    \126\ See Patterson Letter.
    \127\ See Nasdaq Letter at 4.
---------------------------------------------------------------------------

    As the Commission stated in previous orders approving the extension 
of the trading hours of a national securities exchange to include 
overnight time periods, the Commission continually monitors the 
national market system and the operation of Federal securities laws, 
and the Commission, consistent with its oversight of the national 
market system, will continue to monitor the developments of extended 
trading hours.\128\ In addition, consistent with previous orders, the 
monitoring of new market developments does not foreclose Commission 
action on this proposal.\129\ The Commission finds that Nasdaq's rules, 
as amended, for the Night Session are consistent with the Exchange Act. 
Specifically, Nasdaq rules that will govern the Night Session are 
largely based on its rules for the Pre-Market Hours and Post-Market 
Hours sessions with differences, discussed below, as well as the 
additional customer disclosures, to accommodate further expansion of 
trading hours.
---------------------------------------------------------------------------

    \128\ See 24X Approval Order, 89 FR at 97106, NYSE Arca Approval 
Order, 90 FR at 9797.
    \129\ See 24X Approval Order, 89 FR at 97106, and NYSE Arca 
Approval Order, 90 FR at 9797.
---------------------------------------------------------------------------

B. Equity Data Plans and Securities Information Processor Readiness

    With respect to quotation and transaction information, Exchange 
Rule Equity 1, Section 1(a)(19) requires that the Exchange will not 
commence operation of the Night Session prior to the Equity Data Plans' 
readiness to collect, consolidate, process, and disseminate quotation 
and transaction information at all times during the Night Session.\130\ 
Further, Nasdaq Rule Equity 1, Section 1(a)(19) requires the Exchange 
to file a proposed rule change pursuant to Section 19(b) of the 
Exchange Act to amend the Exchange's rules confirming that the Exchange 
is able to comply with its obligations under the Exchange Act and the 
Equity Data Plans are prepared to collect, consolidate, process, and 
disseminate quotation and transaction information at all times during 
the Night Session. The proposed rule change must be filed with the 
Commission and approved, or otherwise become effective pursuant to 
Section 19(b) of the Exchange Act, before Nasdaq can commence trading 
in the Night Session.
---------------------------------------------------------------------------

    \130\ The Exchange has represented that it will submit ``. . . 
all quotes and trades that are generated in the Night Session to the 
consolidated quote and trade systems maintained by the SIPs for 
public dissemination.'' See Footnote 70 of Amendment No. 2. See also 
supra note 76.
---------------------------------------------------------------------------

    The Nasdaq rule requiring the operation of the Equity Data Plans 
during the Night Session is designed to ensure that consolidated 
quotation and transaction information are provided in a manner that is 
consistent with the existing extended hours sessions on exchanges, 
including Nasdaq. The Nasdaq rules for the Night Session are designed 
to perfect the mechanism of a free and open market and a national 
market system, protect investors and the public interest. Further, the 
Amended Proposal will foster competition by introducing another trading 
venue during these trading hours. The Commission has approved other 
national securities exchanges' rules to introduce overnight trading 
hours with substantively identical provisions.\131\
---------------------------------------------------------------------------

    \131\ See 24X Rule 1.5(c) and NYSE Arca Rule 7.34-E.
---------------------------------------------------------------------------

C. Designated Ports

    For the Night Session, the Exchange will require market 
participants to use ports that are specifically designated for the 
Night Session. The following ports will be available for the night 
session: OUCH5, Core FIX, and FIX. The Exchange explained that the 
Night Session will have a distinct instance of the Trading System so 
the Day Session ports will only be capable of connecting to the Day 
Session of the Trading System. The Exchange will cancel all orders on 
the Nasdaq Book at the end of the Day Session and at end of the Night 
Session.
    The use of dedicated ports for the Night Session is consistent with 
the requirements of the Act. The Exchange's proposed use of designated 
ports will allow the Exchange to use different Trading Systems for the 
Day and Night Sessions and will allow the Exchange to manage and 
monitor each session independently.

D. Effect on Retail Investors and Customer Disclosures

    One commenter stated that retail investors do not have the 
resources to monitor their portfolios 23 hours a day and stated that 
the proposal would put retail investors at a disadvantage compared to 
institutional trading firms.\132\ Another commenter stated that 
extended hours trading may have a detrimental impact on investor 
behavior and that retail traders are unlikely to understand the risks 
of overnight trading.\133\ The Exchange responded that its proposal 
adopts mandatory customer disclosures that are substantively identical 
to the corresponding approved rules of 24X.\134\
---------------------------------------------------------------------------

    \132\ See Terranova Letter. See also Better Markets Letter.
    \133\ See Better Markets Letter.
    \134\ See Nasdaq Letter at 3.
---------------------------------------------------------------------------

    Nasdaq's proposed rules are largely based on the previously 
approved overnight trading rules of other national securities 
exchanges.\135\ In addition, while overnight trading is not yet 
operational on any national securities exchanges, it does currently 
occur in the over-the-counter market on multiple ATSs.\136\ 
Accordingly, while Nasdaq's proposal would extend its trading hours 
with the Night Session (9:00 p.m. ET to 4:00 a.m. ET on Sunday, Monday, 
Tuesday, Wednesday and Thursday), market participants, including retail 
investors, are already able to trade during that time.
---------------------------------------------------------------------------

    \135\ See 24X Approval Order and NYSE Arca Approval Order, supra 
note 10.
    \136\ See, e.g., Blue Ocean ATS, LLC (``BOATS''). The operating 
hours for BOATS occur from 8:00 p.m. to 4:00 a.m. E.T. on days when 
the NYSE Trade Reporting Facility is open for trade reporting. See 
Form ATS-N, available at <a href="http://sec.gov/Archives/edgar/data/1795131/000153949723000091/xslATS-N_X01/primary_doc.xml">sec.gov/Archives/edgar/data/1795131/000153949723000091/xslATS-N_X01/primary_doc.xml</a>.
---------------------------------------------------------------------------

    The Exchange has proposed several rules that will help to provide 
investor protections during the Night Session. For example, as 
discussed above, the Exchange proposed to update Equity 2, Section 20, 
which requires customer disclosures concerning the risks associated 
with trading in Extended

[[Page 20234]]

Hours \137\ to include additional risks specifically related to the 
Night Session. These additional risk factors include: (1) trading 
during hours that the primary listing market may not be open to conduct 
surveillance and other regulatory obligations; (2) trading during hours 
in which there may be different or limited regulatory protections such 
as single stock volatility mechanisms; (3) more limited trading 
alternatives may lead to losses if orders cannot be executed due to 
systems failures or other issues on the Exchange; (4) systems 
maintenance and testing may introduce more risks to trading due to less 
breaks in trading to conduct those events; (5) other key financial 
market infrastructure companies may be closed and could cause delays in 
settlement; (6) trading on an exchange during the Night Session is 
novel and may present unforeseen risks; and (7) trading during the 
Night Session may present additional unforeseen risks. These additional 
risk disclosures are substantially similar to the risk disclosures 
already approved by the Commission with respect to other national 
securities exchanges.\138\ Accordingly, Nasdaq's Amended Proposal, 
which adds additional risk disclosures is consistent with the 
requirements of Section 6(b)(5) of the Exchange Act because it is 
designed to protect investors and the public interest.
---------------------------------------------------------------------------

    \137\ See supra note 14.
    \138\ See 24X Approval Order and NYSE Arca Approval Order, supra 
note 10.
---------------------------------------------------------------------------

    Further, the Exchange proposed to limit the types of orders that 
would be allowed in the Night Session and will not accept unpriced 
orders. The Exchange stated that all limit orders permitted to trade in 
the Pre-Market Hours would be eligible for the Night Session, except 
for certain order types that are designated for the opening cross or 
post-open trading. As discussed above, the Exchange would not allow the 
following Order Types during the Night Session: Supplemental; Market 
Maker Peg; Market On Open; Limit on Open; Opening Imbalance Only; 
Market on Close; Limit on Close; Imbalance-Only; Company Direct 
Listing; Extended Trading Close; Midpoint Peg Post-Only; Midpoint 
Extended Life Order; and Midpoint Extended Life Order Plus Continuous 
Book. Moreover, the Exchange would not allow the following Order 
Attributes during the Night Session: Primary Pegging; Market Pegging; 
Midpoint Pegging; and Discretion (Pegging). With respect to Time-in-
Force order attributes, orders entered during the Night Session that 
are designated to deactivate after 4:00 a.m. ET will deactivate at the 
conclusion of the Night Session at 4:00 a.m. ET. Moreover, the Exchange 
stated that limit orders entered during the Night Session will be 
subject to Limit Order Protection, a feature of the Exchange to prevent 
limit order acceptance at prices outside of pre-set limits. Consistent 
with other exchanges that are approved to operate overnight trading 
sessions, Nasdaq will not allow pegged orders or unpriced or market 
orders to be entered during the Night Session. Accordingly, Nasdaq's 
Amended Proposal, which restricts certain order types and order 
attributes, is consistent with the requirements of Section 6(b)(5) of 
the Exchange Act because it is designed to protect investors and the 
public interest.

E. Trading Pause/Transition Between Day and Night Sessions

    To transition into the Night Session, the Exchange will institute a 
trading pause from 8:00 p.m. to 9:00 p.m. on Monday through Thursday 
for testing, system maintenance, and processing corporate actions. The 
Exchange will cancel all outstanding orders at the end of the Day 
Session at 8:00 p.m. and at the end of the Night Session at 4:00 a.m. 
the next calendar day. Nasdaq's proposed daily one-hour pause between 
the operation of the Day Session and the Night Session should be 
sufficient to permit Nasdaq to address the technical implications of a 
23-hour trading day and will facilitate internal market testing and 
systems updates and improvements.

F. Other Proposed Rules

    As described above, the Exchange also proposes various conforming, 
clarifying, and non-substantive changes. These changes, which generally 
delete obsolete references and replace them with the updated and 
relevant defined terms, should help to promote the transparency and 
clarity of the Exchange's rules related to the addition of the Night 
Session. These changes are consistent with the requirements under 
Section 6(b)(5) of the Exchange Act that the rules of an exchange are 
designed to remove impediments to and perfect the mechanism of a 
national market system, and protect investors and the public interest 
because they are designed to provide transparency and clarity to the 
Exchange's rules.

IV. Solicitation of Comments on Amendment Nos. 2 and 3 to the Proposed 
Rule Change

    Interested persons are invited to submit written data, views and 
arguments concerning whether the proposed rule change, as amended by 
Amendment Nos. 2 and 3, is consistent with the Act. Comments may be

V. Accelerated Approval of Proposed Rule Change, as Amended by 
Amendment Nos. 2 and 3

    The Commission finds good cause to approve the Amended Proposal 
prior to the thirtieth day after the date of publication of the notice 
of filing of Amendment Nos. 2 and 3 in the Federal Register. The 
Amended Proposal is substantially similar to the approved rules of 
other national securities exchanges.\139\ Amendment No. 2 revises the 
proposal to change the definition of Business Day and add an additional 
risk disclosure with respect to the Night Session. Amendment No. 2 also 
clarifies that during the Night Session: (1) all NMS Stocks will be 
available for trading; (2) unpriced orders, like pegged orders, will 
not be permitted; \140\ (3) CE

[[Page 20235]]

Rules and LOP will be applicable; \141\ (4) M-ELO orders will be 
rejected; \142\ and (5) the Night Session specific ports will use the 
OUCH 5 technology; \143\ in addition to other non-substantive changes 
to conform and clarify the proposed rule text. Amendment No. 3 
clarifies that Amendment No. 2 replaced and superseded and replaced the 
original proposal in its entirety.

note 10.
    \140\ See proposed Nasdaq Rule 4702.

    \143\ See proposed Nasdaq Rule 4702(a).
---------------------------------------------------------------------------

    In light of the previous Commission orders approving other national 
securities exchanges' rules to allow trading during the times that 
coincide with the Night Session, and the substantive similarity of 
Nasdaq's Amended Proposal to those existing exchange rules, Amendment 
Nos. 2 and 3 do not raise any new or novel regulatory issues. 
Accordingly, the Commission finds good cause, pursuant to Section 
19(b)(2) of the Act,\144\ to approve the Amended Proposal, prior to the 
thirtieth day after the date of publication of the notice of Amendment 
Nos. 2 and 3 thereof in the Federal Register.
