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 Exchange proposes to amend Rule 11.9(c)(8) to clarify Pegged 
Order operation and to align BYX Rules with the rules of its affiliate 
exchanges in order to provide consistency amongst the Exchange and its 
affiliates. The Exchange notes that the proposed rule text is based on 
EDGA/EDGX Rule 11.6(j) and is different only to the extent necessary to 
conform to the Exchange's current rules.\5\ The proposed amendment does 
not propose to implement new or unique functionality that has not been 
previously filed with the Commission or is not available on EDGA or 
EDGX.
---------------------------------------------------------------------------

    \5\ To the extent a proposed rule change is based on existing 
EDGA and EDGX Rules, the language of the EDGA, EDGX, and Exchange 
Rules may differ to extent necessary to conform with existing 
Exchange rule text or to account for details or descriptions 
included in the Exchange Rules but not currently included in EDGA 
and EDGX Rules based on the current structure of such rules.
---------------------------------------------------------------------------

    By way of background, Exchange Rule 11.9, Orders and Modifiers, 
lists and describes the types of orders Users \6\ may enter into the 
System,\7\ including Pegged Orders as described in Exchange Rule 
11.9(c)(8). A Pegged Order \8\ is a limit order that after entry into 
the System, the price of the order is automatically adjusted by the 
System in response to changes in the NBBO.\9\ A Pegged Order will peg 
to the NBB or NBO or a certain amount away from the NBB \10\ or 
NBO,\11\ as described in Exchange Rules 11.9(c)(8)(A) and 
11.9(c)(8)(B). Pegged Orders are not eligible for routing pursuant to 
Exchange Rule 11.13(b).\12\ A new time stamp is created for a Pegged 
Order each time it is automatically adjusted.\13\
---------------------------------------------------------------------------

    \6\ See Exchange Rule 1.5(cc).A ``User'' is defined as ``any 
Member or Sponsored Participant who is authorized to obtain access 
to the System pursuant to Rule 11.3.
    \7\ See Exchange Rule 1.5(aa).The ``System'' is defined as ``the 
electronic communications and trading facility designated by the 
Board through which securities orders of Users are consolidated for 
ranking, execution and, when applicable, routing away.''
    \8\ See Rule 11.9(c)(8).
    \9\ See Rule 1.5(o). The term ``NBBO'' shall mean the national 
best bid or offer.
    \10\ See Rule 1.5(o). The term ``NBB'' shall mean the national 
best bid.
    \11\ See Rule 1.5(o). The term ``NBO'' shall mean the national 
best offer.
    \12\ See Rule 11.9(c)(8).
    \13\ Id.
---------------------------------------------------------------------------

    A Pegged Order may be a Primary Pegged Order or a Market Pegged 
Order.\14\ A Primary Pegged Order will have its price pegged by the 
System to the NBB, for a buy order, or the NBO for a sell order.\15\ A 
User may, but is not required to, specify that such order's price will 
offset the inside quote on the same side of the market by an amount set 
by the User (the ``Primary Offset Amount'').\16\ A Primary Pegged Order 
is eligible to be displayed or non-displayed, however, the Primary 
Offset Amount for a displayed Primary Pegged Order must result in the 
price of such order being inferior to or equal to the inside quote on 
the same side of the market.\17\ A displayed Primary Pegged Order with 
a Primary Offset Amount shall only include a time-in-force of RHO,\18\ 
or if entered during Regular Trading Hours,\19\ a time-in-force of 
Day.\20\
---------------------------------------------------------------------------

    \14\ Id.
    \15\ See Rule 11.9(c)(8)(A).
    \16\ Id.
    \17\ Id.
    \18\ See Rule 11.9(b)(7). A time-in-force of Regular Hours Only 
(``RHO'') may be applied to a limit or market order that is 
designated for execution only during Regular Trading Hours, which 
includes the Opening Auction, the Closing Auction, and IPO/Halt 
Auctions for BYX listed securities and the Opening Process for non-
BYX-listed securities (as such terms are defined in Rule 11.23 and 
11.24). Any portion of a market RHO order will be cancelled 
immediately following any auction in which it is not executed.
    \19\ See Rule 1.5(w). The term ``Regular Trading Hours'' means 
the time between 9:30 a.m. and 4:00 p.m. Eastern Time.
    \20\ See Rule 11.8(b)(2). A time-in-force of Day may be applied 
to a limit order to buy or sell, which, if not executed, expires at 
the end of Regular Trading Hours. Any Day Order entered into the 
System before the opening of business on the Exchange as determined 
pursuant to Rule 11.1, or after the closing of Regular Trading 
Hours, will be rejected.
---------------------------------------------------------------------------

    A Market Pegged Order has its price pegged by the System to the 
NBB, for a sell order, or the NBO, for a buy order.\21\ A User entering 
a Market Pegged Order can specify that such order's price will offset 
the inside quote on the contra side of the market by an amount set by 
the User (the ``Offset Amount'').\22\ A Market Pegged Order is not 
eligible to be displayed on the Exchange.\23\
---------------------------------------------------------------------------

    \21\ See Rule 11.9(c)(8)(B).
    \22\ Id.
    \23\ Id.
---------------------------------------------------------------------------

    Now, the Exchange proposes to amend the description of a Pegged 
Order under Rule 11.9(c)(8) to align with EDGA/EDGX Rule 11.6(j) and to 
clarify that a Pegged Order will not be eligible for execution where 
the NBB or NBO, as applicable, is no longer available. Further, the 
proposed rule text will provide that a new timestamp is created for an 
order that has been ineligible for execution and again becomes eligible 
for execution because the NBB or NBO it is pegged to becomes 
unavailable [sic].
    Currently, when the NBB or NBO becomes unavailable, a Pegged Order 
is cancelled back to the User. As proposed, instead of being cancelled 
back to the User, a Pegged Order will remain on the BYX Book. When the 
NBB or NBO that the Pegged Order is pegged to becomes available again, 
the order will receive a new time stamp and be eligible for execution. 
The proposed rule change provides additional detail with regard to the 
operation of Pegged Orders when the NBB or NBO, as applicable, is 
unavailable, that is currently not included in Exchange Rule 11.9(c). 
This proposed rule change does not propose to implement new or unique 
functionality that has not been previously filed with the Commission or 
is not available on EDGA or EDGX.
Statutory Basis
    The Exchange believes the proposed rule change is consistent with 
the Securities Exchange Act of 1934 (the ``Act'') and the rules and 
regulations thereunder applicable to the Exchange and, in particular, 
the requirements of Section 6(b) of the Act.\24\ Specifically, the 
Exchange believes the proposed rule change is consistent with the 
Section 6(b)(5) \25\ requirements that the rules of an exchange be 
designed to prevent fraudulent and manipulative acts and practices, to 
promote just and equitable principles of trade, to foster cooperation 
and coordination with persons engaged in regulating, clearing, 
settling, processing information with respect to, and facilitating 
transactions in securities, 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. Additionally, 
the Exchange believes the proposed rule change is consistent with the 
Section 6(b)(5) \26\ requirement that

[[Page 60821]]

the rules of an exchange not be designed to permit unfair 
discrimination between customers, issuers, brokers, or dealers. The 
proposed rule change is designed to support the principles of Section 
11A(a)(1) \27\ of the Act in that it seeks to assure fair competition 
among brokers and dealers and among exchange markets.

    \26\ Id.
    \27\ 15 U.S.C. 78k-1(a)(1).
---------------------------------------------------------------------------

    The proposed rule change is intended to more thoroughly describe 
Pegged Order operation and to align BYX Rules with the rules of its 
affiliate exchanges in order to provide consistent offerings amongst 
the Exchange and its affiliates, which the Exchange believes is 
designed to remove impediments to and perfect the mechanism of a free 
and open market and a national market system, thereby protecting 
investors and the public interest. Consistency amongst the rules of the 
Exchange and its affiliates, in turn, will promote rule compliance for 
Users of the Exchange that are also participants on EDGA and/or EDGX. 
The proposed rule change does not propose to implement new or unique 
functionality that has not been previously filed with the Commission or 
is not described in the rules of its affiliate exchanges. By aligning 
BYX Rules with the rules of EDGA and EDGX, the Exchange believes the 
proposed rule change will remove impediments to the mechanism of a free 
and open market and protect investors by providing investors with 
increased transparency regarding rules that reflect the behavior of 
Pegged Order on the Exchange when the NBB or NBO, as applicable, 
becomes unavailable. As a result, the Exchange's proposal will promote 
just and equitable principles of trade and remove impediments to and 
perfect the mechanism of a free and open market and a national market 
system. Additionally, the proposal does not permit unfair 
discrimination among customers, brokers, or dealers because the 
proposed Pegged Order behavior will apply to all Users equally in that 
any User's Pegged Order will become non-executable in the event that 
the NBB or NBO, as applicable, becomes unavailable and a Pegged Order 
will receive a new timestamp when the NBB or NBO becomes available and 
the order again becomes eligible for execution.
    As described above, the proposed amendment is designed to ensure 
clarity in the Exchange's rulebook with respect to the operation of 
Pegged Orders in the event that the NBB or NBO, as applicable, becomes 
unavailable. The Exchange notes that the proposed amendment is based on 
EDGA/EDGX Rule 11.6(j) and is different only to the extent necessary to 
conform to the Exchange's current rules. Thus, the proposed amendment 
to Rule 11.9(c)(8) is directly targeted at removing impediments to and 
perfecting the mechanism of a free and open market and national market 
system, as well as to assure fair competition among brokers and dealers 
and among exchange markets.

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

    The Exchange does not believe that the proposed rule change will 
impose any burden on competition that is not necessary or appropriate 
in furtherance of the purposes of the Act. The Exchange notes that the 
proposed amendment to clarify Pegged Order behavior will provide 
consistent offerings amongst the Exchange and its affiliates. The 
Exchange does not believe the proposed change will have any impact on 
intermarket competition as the proposal is not being made for 
competitive reasons, but rather to align the text of BYX Rule 
11.9(c)(8) with the corresponding rule text of its affiliate exchanges. 
In addition, the Exchange believes the proposed rule change will 
benefit all Users in that Users will have a more complete understanding 
of Pegged Order behavior when the NBB or NBO, as applicable, becomes 
unavailable. The proposed rule change will apply equally to all Users 
of Pegged Orders.
    The Exchange does not believe that the proposed amendments will 
impose any burden on intra-market competition that is not necessary or 
appropriate in furtherance of the purposes of the Act. The Exchange 
provides services in a highly competitive market in which participants 
may avail themselves of a wide variety of order types and order 
operations offered by self-regulatory organizations, other broker-
dealers, market participants' own proprietary routing systems, and 
service bureaus. In such an environment, more detailed descriptions of 
the types of orders Users may enter into the System, such as the 
changes proposed in this rule filing do not burden competition, because 
they can succeed in attracting order flow to the Exchange only if they 
offer investors higher quality and better value than services offered 
by others. The Exchange reiterates that the proposed rule change to 
clarify Pegged Order behavior is being proposed in an effort to add 
consistency to offerings across the Exchange and its affiliates.

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

    The Exchange neither solicited nor received comments on the 
proposed rule change.

III. Date of Effectiveness of the Proposed Rule Change and Timing for 
Commission Action

    Because the foregoing proposed rule change does not:
    A. significantly affect the protection of investors or the public 
interest;
    B. impose any significant burden on competition; and
    C. become operative for 30 days from the date on which it was 
filed, or such shorter time as the Commission may designate, it has 
become effective pursuant to Section 19(b)(3)(A) of the Act \28\ and 
Rule 19b-4(f)(6) \29\ thereunder. At any time within 60 days of the 
filing of the proposed rule change, the Commission summarily may 
temporarily suspend such rule change if it appears to the Commission 
that such action is necessary or appropriate in the public interest, 
for the protection of investors, or otherwise in furtherance of the 
purposes of the Act. If the Commission takes such action, the 
Commission will institute proceedings to determine whether the proposed 
rule change should be approved or disapproved.
