of the Proposed Rule Change

    Cboe Exchange, Inc. (the ``Exchange'' or ``Cboe Options'') proposes 
to amend Rule 5.34(c) with respect to its Risk Monitor Mechanism, to 
provide Users with additional flexibility in establishing how their 
trading activity counts towards certain risk parameters. The text of 
the proposed rule change is provided in Exhibit 5.
    The text of the proposed rule change is also available on the 
Commission's website (<a href="https://www.sec.gov/rules/sro.shtml">https://www.sec.gov/rules/sro.shtml</a>), the 
Exchange's website (<a href="https://www.cboe.com/us/options/regulation/rule_filings/bzx/">https://www.cboe.com/us/options/regulation/rule_filings/bzx/</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 Exchange proposes to amend Rule 5.34(c), Order and Quote Price 
Protection Mechanisms and Risk Controls (All Orders). Specifically, the 
Exchange proposes changes to the Risk Monitor Mechanism to provide 
Users with additional flexibility in establishing how their trading 
activity counts towards certain risk parameters.
    By way of background, the Risk Monitor Mechanism provides Users \3\ 
with the ability to manage their order and execution risk. Each User 
may establish limits for various parameters in the Exchange's counting 
program. The System \4\ counts each of the following within a class for 
an EFID \5\ (``class limit'') and across all classes for an EFID 
(``EFID limit'') and/or for all classes for a group of EFIDs (``EFID 
Group'') (``EFID Group limit''), over a User-established time period 
(``interval'') and on an absolute basis for a trading day (``absolute 
limits''): (i) number of contracts executed (``volume''); (ii) notional 
value of executions (``notional''); (iii) number of executions 
(``count''); (iv) number of contracts executed as a percentage of 
number of contracts outstanding within an Exchange-designated time 
period or during the trading day, as applicable (``percentage''), which 
the System determines by calculating the percentage of a User's 
outstanding contracts that executed on each side of the market during 
the time period or trading day, as applicable, and then summing the 
series percentages on each side in the class; and (v) number of times 
the limits established by the parameters (i) through (iv) are reached 
(``risk trips'') (collectively, ``risk parameters''). Additionally, 
when the System determines a risk parameter exceeds a User's class 
limit within the interval or the absolute limit for the class, the Risk 
Monitor Mechanism cancels or rejects such User's orders or quotes in 
all series of the class and cancels or rejects any additional orders or 
quotes from the User in the class until the counting program resets. 
Similarly, when the System determines a risk parameter exceeds a User's 
EFID limit within the interval or the absolute limit for the EFID, the 
Risk Monitor Mechanism cancels or rejects such User's orders or quotes 
in all classes and cancels or rejects any additional orders or quotes 
from the EFID in all classes until the counting program resets. 
Finally, when the System determines a risk parameter exceeds a User's 
EFID Group limit within the interval or the absolute limit for the EFID 
Group, the Risk Monitor Mechanism cancels or rejects such User's orders 
or quotes in all classes and cancels or rejects any additional orders 
or quotes from any EFID within the EFID Group in all classes until the 
counting program resets.
---------------------------------------------------------------------------

    \3\ The term ``User'' means any TPH or Sponsored User who is 
authorized to obtain access to the System pursuant to Rule 5.5. See 
Rule 1.1.
    \4\ The term ``System'' means the Exchange's hybrid trading 
platform that integrates electronic and open outcry trading of 
option contracts on the Exchange, and includes any connectivity to 
the foregoing trading platform that is administered by or on behalf 
of the Exchange, such as a communications hub. See Rule 1.1.
    \5\ The term ``EFID'' means an Executing Firm ID. See Rule 1.1.
---------------------------------------------------------------------------

    The Exchange proposes to amend Rule 5.34(c) to enhance the Risk 
Monitor Mechanism to provide Users with additional flexibility in

[[Page 3764]]

establishing how their trading activity counts towards certain risk 
parameters.
    First, the Exchange proposes to add new Rule 5.34(c)(4)(B)(i) \6\ 
to allow Users the option to exclude certain options auction-executed 
volume from certain of the Risk Monitor Mechanism risk parameters, 
namely the volume parameter in Rule 5.34(c)(4)(A)(i) and the count 
parameter in Rule 5.34(c)(4)(A)(iii). Under the proposed change, a User 
may specify whether volume or executions in Automated Improvement 
Mechanism Auctions (``AIM''), Complex-AIM (``C-AIM''), Solicitation 
Auction Mechanism Auctions (``SAM''), Complex-SAM (``C-SAM''), Step Up 
Mechanism Auctions (``SUM''), and Complex Order Auctions (``COA'') 
count toward the User's class, EFID, or EFID Group limit (on both an 
interval or absolute basis).
---------------------------------------------------------------------------

    \6\ As part of the proposed change, the Exchange proposes to 
renumber current Rules 5.34(c)(4)(B), (C), (D), (E), and (F) as 
Rules 5.34(c)(4)(C), (D), (E), (F), and (G), respectively.
---------------------------------------------------------------------------

    The Exchange also proposes to add new Rule 5.34(c)(4)(B)(ii) to 
allow Users the option to establish the volume or count parameters on a 
contra-party capacity basis. Under the proposed change, a User may 
specify a percentage (up to 100%) of volume or executions to count 
toward the User's class, EFID, or EFID Group limit based on contra-
party capacity (on both an interval or absolute basis). For example, 
under the proposed rule change, a User could specify that only 20% of 
the quantity on each trade with a Capacity ``C'' (i.e., Public 
Customer) \7\ contra-party would be counted towards the User's class, 
EFID, or EFID Group limit (on an interval or absolute basis).
---------------------------------------------------------------------------

    \7\ See Rule 1.1 (definition of ``Capacity'').
---------------------------------------------------------------------------

    The proposed changes allow the User to more precisely tailor the 
volume and count parameters within the Risk Monitor Mechanism. The 
Exchange notes that use of the proposed enhancements is optional, and 
Users are free to utilize them or not, at their discretion.
2. 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.\8\ Specifically, the 
Exchange believes the proposed rule change is consistent with the 
Section 6(b)(5) \9\ 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) \10\ requirement that the rules of an exchange not be 
designed to permit unfair discrimination between customers, issuers, 
brokers, or dealers.

    \9\ 15 U.S.C. 78f(b)(5).
    \10\ Id.
---------------------------------------------------------------------------

    In particular, the Exchange believes the proposed change would 
remove impediments to and perfect the mechanism of a free and open 
market and a national market system, and protect investors and the 
public interest by providing Users with enhanced abilities to manage 
their risk with respect to orders on the Exchange. The Exchange 
believes that allowing Users to tailor volume and count parameters 
promotes risk management processes that better reflect the risks of 
different types of trading activity. The Exchange believes that the 
proposed rule change will protect investors and the public interest 
because the proposed enhancements will assist Users in minimizing their 
risk exposure, thereby reducing the potential for disruptive, market-
wide events.
    The Exchange believes the proposed change to allow Users to specify 
whether volume or executions in AIM, C-AIM, SAM, C-SAM, SUM and COA 
count toward the User's class, EFID, or EFID Group limit (on both an 
interval or absolute basis) is reasonable because orders executed 
through these auction mechanisms are subject to different protections, 
such as price improvement requirements or exposure periods, as compared 
to other order types. As a result, these orders have different risk 
considerations. Allowing Users to differentiate between these execution 
types in their Risk Monitor Mechanism settings enables them to 
establish risk parameters that more accurately reflect their risk 
management tolerances. The Exchange again notes that this functionality 
is optional, and Users may continue to include executions resulting 
from these exchange auctions in their risk parameters (as is the case 
today) if they prefer.
    The Exchange also believes its proposal to allow Users to establish 
volume or count parameters on a contra-party capacity basis is 
reasonable, as different contra-party types present different risk 
profiles. For example, this enhancement may be beneficial for Market-
Makers or other liquidity providers who may wish to establish lower 
limits for when providing liquidity to Customer orders while 
establishing stricter parameters for trades against other institutional 
contra-parties which may involve different risk considerations. The 
Exchange believes allowing Users the option to adjust their risk 
tolerance based on contra-party capacity provides the opportunity for a 
more precise risk management approach.
    Finally, the Exchange believes the proposed changes are not 
unfairly discriminatory, as the proposed enhancements are available to 
all Users and apply uniformly to all Users who may choose to utilize 
the enhanced risk parameter settings. As noted above, use of the 
proposed enhancements is optional and Users are free to utilize them or 
not, at their discretion.

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 does not 
believe that the proposed rule change will impose any burden on 
intramarket competition that is not necessary or appropriate in 
furtherance of the purposes of the Act, because the proposed 
enhancements are available to all Users and apply uniformly to all 
Users who may choose to utilize the enhanced risk parameter settings. 
As noted above, use of the proposed enhancements is optional and Users 
are free to utilize them or not, at their discretion.
    Additionally, the Exchange does not believe that the proposed rule 
change will impose any burden on intermarket competition that is not 
necessary or appropriate in furtherance of the purposes of the Act 
because the proposed enhancements apply only to trading on the 
Exchange. Again, the Exchange notes that it is voluntary for the Users 
to determine whether to make use of the new enhancements of the Risk 
Monitor Mechanism. To the extent that the proposed changes may make the 
Exchange a more attractive trading venue for market participants on 
other exchanges, such market participants may elect to become Exchange 
market participants.

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.
