Pursuant to Section 19(b)(1) of the Securities Exchange Act of 1934
(``Act''),\1\ and Rule 19b-4 thereunder,\2\ notice is hereby given that
on January 21, 2022, Cboe EDGX Exchange, Inc. (``Exchange'') filed with

I. Self-Regulatory Organization's Statement of the Terms of Substance
of the Proposed Rule Change
Cboe EDGX Exchange, Inc. (``EDGX'' or the ``Exchange'') is filing
with the Securities and Exchange Commission (the ``Commission'') a
proposal to codify certain practices and requirements related to the
Exchange's port message rate thresholds, and to promote transparency
and maintain clarity in the rules. The text of the proposed rule change
is provided in Exhibit 5.
The text of the proposed rule change is also available on the
Exchange's website (<a href="http://markets.cboe.com/us/options/regulation/rule_filings/edgx/">http://markets.cboe.com/us/options/regulation/rule_filings/edgx/</a>), at the Exchange's Office of the Secretary, and at
the Commission's Public Reference Room.
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 this rule filing is to codify certain of the
Exchange's current practices and requirements related to its port
message rate thresholds, which it believes will promote transparency
and maintain clarity in its rules. Specifically, the Exchange is
proposing to add new Rule 11.23, titled Port Message Rate Threshold, in
order to memorialize the Exchange's ability to establish per port
message rate limits applicable to its Members. The Exchange has
historically provided Members with information regarding the port order
rate threshold, as defined below, in its publicly available technical
specifications,\3\ but to promote transparency, the Exchange is
proposing to codify the Exchange's discretion to impose such limits in
its rulebook. The System \4\ does not have unlimited port capacity to
consistently support an unlimited number of messages throughout the
trading day. For this reason, the Exchange limits each Member to a
maximum number of messages over a set amount of time, per port
(hereinafter the ``Port Order Rate Thresholds''). While Members may
elect to establish a lower Port Order Rate Threshold, each Member is
subject to the same maximum Port Order Rate Threshold. Like other
exchanges,\5\ EDGX currently imposes a maximum Port Order Rate
Threshold, at its discretion, and notifies its Members of such maximum
number through the Exchange's publicly available technical
specifications.\6\ Consistent with this current functionality, proposed
Rule 11.23 would memorialize that all Members shall be subject to a
Port Order Rate Threshold, as determined by the Exchange in its
discretion.
---------------------------------------------------------------------------
\3\ Port Order Rate Threshold is defined as the maximum allowed
message rate on a port. See Cboe FIX Specifications, available at:
<a href="https://cdn.cboe">https://cdn.cboe</a>./resources/membership/
Cboe_US_Equities_FIX_Specification.pdf. See also Cboe BOE
Specifications, available at: https://cdn..com/resources/membership/
Cboe_US_Equities_BOE_Specification.pdf.
\4\ The term ``System'' shall mean 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. See Rule 1.5(cc).
\5\ E.g., Section 5.7 of the New York Stock Exchange's technical
specifications states, ``In order to protect the Trading Engine from
an overload of incoming messages, the CGC Gateway employs a session-
level throttle mechanism. This is a configurable value currently set
to 1000 messages per second on a rolling 1 second basis. In the
event this throttle mechanism is activated, the gateway will slow
the sending of incoming messages down to the Trading Engine during
the throttle period (i.e., messages will be queued) so as to not
exceed the defined message threshold. See <a href="https://www.nyse.com///markets//NYSE_CCG_FIX_Specification.pdf">https://www.nyse.com///markets//NYSE_CCG_FIX_Specification.pdf</a>.
\6\ E.g., page 73, ``Port Order Rate Threshold'', of the Cboe
U.S. Equities FIX Technical Specifications, which denotes the
current maximum allowed message rate on the port. When the first
non-administrative message is received, a one second window begins.
During the second no more than 4,999 additional non-administrative
messages will be allowed within that window. If the rate is exceeded
all new orders in the time window are rejected, modifies are treated
as cancels, and cancels are processed. If maximum rate limit of
10,000 is requested, no more than 9,999 additional non-
administrative messages will be allowed within that one second
window.
---------------------------------------------------------------------------
The Exchange notes that proposed Rule 11.23 is based on
substantially similar rules that historically \7\ existed in the Cboe
Options Exchange (``C1'')
[[Page 7520]]
and the Cboe C2 Options Exchange (``C2'') rulebooks, as well as MIAX
Rule 502 (``Message Packets'') which currently exists in the MIAX
Options and MIAX Emerald (collectively, ``MIAX'') rulebooks.\8\ Like
new Rule 11.23, C1 Rule 6.23B \9\ (Bandwidth Packets), C2 Rule 6.35
\10\ (Message Packets), and MIAX Rule 502 provide(d) that Trading
Permit Holders are entitled to a maximum number of orders and quotes
per second as determined by C1/C2 or MIAX.
---------------------------------------------------------------------------
\7\ In 2016, Cboe Global Markets, Inc. the parent company of C1
and C2, acquired Cboe EDGA Exchange Inc., Cboe EDGX Exchange, Inc.,
Cboe BZX Exchange, Inc., and Cboe BYX Exchange, Inc. (collectively,
the ``Cboe Affiliated Exchanges''). Subsequent to the acquisitions,
the Cboe Affiliated Exchanges sought to align their rulebooks,
retaining only intended differences between the Cboe Affiliated
Exchanges. As part of this process C1 Rule 6.23B and C2 Rule 6.35
were removed from the C1 and C2 rulebooks. See SR-CBOE-2019-033
(<a href="https://cdn.cboe">https://cdn.cboe</a>.com/resources/regulations/rule_filings/approved/
2019/SR-CBOE-2019-033.pdf.)
\8\ See MIAX Options and MIAX Emerald Rule 502 (``Message
Packets'').
\9\ Rule 6.23B and 6.35 provided: Each Trading Permit shall
entitle the holder to a maximum number of orders and quotes per
second(s) as determined by the Exchange. Only Market-Makers may
submit quotes. Trading Permit Holders seeking to exceed that number
of messages per second(s) may purchase additional bandwidth packets
at prices set forth in the Exchange's Fees Schedule. The Exchange
shall, upon request and where good cause is shown, temporarily
increase a Trading Permit Holder's order entry bandwidth allowance
at no additional cost. All determinations to temporarily expand
bandwidth allowance shall be made in a non-discriminatory manner and
on a fair and equal basis. No bandwidth limits shall be in effect
during pre-opening prior to 8:25 a.m. CT, which shall apply to all
Trading Permit Holders. The Exchange may also determine time periods
for which there shall temporarily be no bandwidth limits in effect
for all Trading Permit Holders. Any such determination shall be made
in the interest of maintaining a fair and orderly market. The
Exchange shall notify all Trading Permit Holders of any such
determination.''
\10\ Id.
---------------------------------------------------------------------------
The Exchange further notes that C1 Rule 6.23B, C2 Rule 6.35, and
MIAX Rule 502 provide(d) for certain other messaging restrictions and
actions not included in proposed Rule 11.23; namely, the restriction
that only a Market-Maker \11\ may enter quotes, and language noting the
ability of Trading Permit Holders to purchase additional bandwidth
packets at the prices set forth in the exchanges' fee schedule.
However, these changes are not necessary for the purposes of proposed
Rule 11.23 because all Exchange Members, not just Market Makers, may
submit messages to the Exchange. Additionally, it is already clear from
the Exchange's fee filings \12\ that additional ports are available for
purchase. Additionally, C1 Rule 6.23B and C2 Rule 6.35, provided those
exchanges with the discretion to temporarily increase, upon request, a
Member's limits, as well as the discretion to designate time periods
when Members shall not be subject to a message limit. This language is
not included in this rule filing because the Exchange is not currently
proposing to allow Members to request temporary message rate increases
or to designate time periods when Members shall not be subject to a
message limit.
---------------------------------------------------------------------------
\11\ The C1 and C2 Rulebooks defined ``Market-Maker'' as a
Trading Permit Holder registered with the Exchange for the purpose
of making markets in options contracts traded on the Exchange and
that is vested with the rights and responsibilities specified in
Chapter 5 of the Rules.
\12\ See EDGX Exchange fees, effective December 1, 2021,
available at: <a href="https://www.cboe.com/us/equities/membership/fee_schedule/edgx/">https://www.cboe.com/us/equities/membership/fee_schedule/edgx/</a>.
---------------------------------------------------------------------------
2. Statutory Basis
The Exchange believes the proposed rule changes are consistent with
the requirements of Section 6(b) of the Act,\13\ in general, and
Section 6(b)(5) of the Act,\14\ in particular, in that it is 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 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.
---------------------------------------------------------------------------
\13\ 15 U.S.C. 78f(b).
\14\ 15 U.S.C. 78f(b)(5).
---------------------------------------------------------------------------
Specifically, the Exchange believes that proposed Rule 11.23 does
not unfairly discriminate amongst market participants. Under proposed
Rule 11.23, Members may elect a lower Port Order Rate Threshold, but
all Members are limited to the same maximum Port Order Rate Threshold.
Moreover, by providing the Exchange with the explicit discretion to
impose Port Order Rate Thresholds, proposed Rule 11.23 helps to foster
a free and open national market system, as well as the Commission's
goal of ensuring that critical market infrastructure has ``levels of
capacity, integrity, availability, and security adequate to maintain
their operational capability and promote the maintenance of fair and
order market''.\15\
---------------------------------------------------------------------------
\15\ See Securities and Exchange Act Release No. 73639 (November
19, 2014) 79 FR 72251 (December 5, 2014) (File No. S7-01-13)
(Regulation SCI Adopting Release).
---------------------------------------------------------------------------
As noted above the Exchange's Systems do not have unlimited port
capacity to consistently support an unlimited number of messages
throughout the trading day. As such, it is critical that the Exchange
maintain discretion to impose Port Order Rate Thresholds to ensure that
Members are not able to submit orders in quantities that degrade the
capacity and performance of Members' ports, as well as the Exchange
systems through which securities orders of Members are consolidated for
ranking, execution and, where applicable, routing away.\16\
---------------------------------------------------------------------------
\16\ See Section 6(b) of the Securities and Exchange Act of 1934
(the ``Act''), 15 U.S.C. 78f (National Securities Exchanges), which
requires that exchanges have the capacity to carry out the purposes
of an exchange under the Act.
---------------------------------------------------------------------------
B. Self-Regulatory Organization's Statement on Burden on Competition
The Exchange does not believe that the proposed rule change imposes
any burden on competition that is not necessary or appropriate in
furtherance of the purposes of the Act. Rather, the proposed rule
change seeks merely to provide Members with additional clarity and
transparency regarding Exchange port message rate limits.
Importantly, the Exchange notes that similar to other exchanges,
proposed rule 11.23 does not include an explicit number of messages or
range of messages, that may be imposed by the Exchange, in its
discretion. Accordingly, proposed Rule 11.23 places the Exchange on par
with its peer exchanges by preserving the Exchange's ability to adjust
the port order rate threshold as needed, to ensure the Exchange's
operational resiliency.
C. Self-Regulatory Organization's Statement on Comments on the Proposed
Rule Change Received From Members, Participants, or Others
The Exchange has not solicited, and does not intend to solicit,
comments on this proposal. No written comments were solicited or
received on the proposed rule change.
III. Date of Effectiveness of the Proposed Rule Change and Timing for
Commission Action

Federal Register or within such longer period up to 90 days (i) as the
Commission may designate if it finds such longer period to be

which the Exchange consents, the Commission will:
A. By order approve or disapprove such proposed rule change, or
B. institute proceedings to determine whether the proposed rule
change should be disapproved.
