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

    The Exchange proposes to amend Equity 4, Rule 3307, as described 
further below. The text of the proposed rule change is available on the 
Exchange's website at https://listingcenter.nasdaq.com/rulebook/phlx/rules, at the principal office of the Exchange, 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 the proposed rule change is to enhance the anti-
internalization functionality available on the Exchange by giving 
market participants the flexibility to choose to have this protection 
apply to market participants under Common Ownership.\3\ Anti-
internalization, also known as self-match prevention, is an optional 
feature available on the Exchange that (1) prevents two orders with the 
same Market Participant Identifier (MPID) from executing against each 
other, or (2) prevents two orders entered through a specific order 
entry port from executing against each other (in the case of market 
participants using the OUCH order entry protocol). The proposed rule 
change would permit market participants to direct that quotes/orders 
entered into the System not execute against quotes/orders entered 
across MPIDs that are under Common Ownership. The Exchange believes 
that this enhancement will provide helpful flexibility for market 
participants that wish to prevent trading against all quotes and orders 
entered by market participants under Common Ownership, instead of just 
quotes and orders that are entered under the same MPID or under a 
particular order entry port.
---------------------------------------------------------------------------

    \3\ The proposed rule change would define ``Common Ownership'' 
under Equity 4, Rule 3307 to mean participants under 75% common 
ownership or control.
---------------------------------------------------------------------------

    Currently, under Equity 4, Rule 3307, the Exchange provides 
optional anti-

[[Page 65632]]

internalization functionality whereby quotes and orders entered by 
market participants using the same MPID are not executed against each 
other. In addition, under Equity 4, Rule 3307, market participants 
using the OUCH order entry protocol may assign to orders entered 
through a specific order entry port a unique group identification 
modifier that will prevent quotes/orders with such modifier from 
executing against each other.\4\ Self-match prevention functionality 
assists participants in reducing trading costs from unwanted executions 
potentially resulting from the interaction of executable buy and sell 
trading interest from the same firm.
---------------------------------------------------------------------------

    \4\ The group identification modifier allows firms to apply 
self-match prevention on a more granular level (i.e., per a specific 
order entry port).
---------------------------------------------------------------------------

    The Exchange currently provides three versions of self-match 
prevention functionality to allow participants to choose how orders are 
handled in the event of a self-match situation: (1) decrement, (2) 
cancel oldest, and (3) cancel newest. Under the first version 
(``decrement''), if the self-match orders have the same share size, 
both orders will cancel back to the customer. If the orders are not 
equivalent in size, the smaller order will cancel back to the 
originating customer and the larger order will decrement by the size of 
the smaller order. The remaining shares of the larger order will remain 
on the book. Under the second version (``cancel oldest''), the full 
size of the order residing on the book will cancel back to the customer 
if the incoming order would execute against it. The incoming order will 
remain intact with no changes. Under the third version (``cancel 
newest''), the full size of the order coming into the book will cancel 
back to the customer. The resting order will remain intact with no 
changes. Currently, firms may opt-in to any version of the self-match 
prevention functionality on a per MPID basis or per port basis.
    Today, the anti-internalization protection prevents market 
participants from trading against their own quotes and orders at the 
MPID or port level. The proposed enhancement to this functionality 
would allow participants to choose to have this protection applied at 
the MPID or port level as implemented today, or across MPIDs under 
Common Ownership. If participants choose to have this protection 
applied across MPIDs under Common Ownership, the anti-internalization 
functionality would prohibit quotes and orders from different MPIDs 
associated with the same Organization ID (``OrgId'') \5\ from trading 
against one another. Under the proposed rule change, the anti-
internalization functionality would continue to be an optional feature. 
If a firm chooses to take advantage of self-match prevention, the firm 
would need to opt-in to the self-match prevention functionality, as is 
the case today. If participants opt-in to the self-match prevention 
functionality, under the proposed rule change, participants would have 
the option to choose whether to apply the protection at the OrgId, 
MPID, or port level. In addition, participants may opt-in to any 
version of the self-match prevention strategy that exists today (i.e., 
decrement, cancel oldest, or cancel newest).\6\
---------------------------------------------------------------------------

    \5\ The OrgId is a field that indicates Common Ownership across 
multiple MPIDs.
    \6\ If the self-match prevention strategy differs between two 
orders, the strategy of the order removing liquidity applies.
---------------------------------------------------------------------------

    The Exchange believes that the proposed anti-internalization 
enhancement would provide participants with more tailored self-trade 
functionality that allows them to manage their trading as appropriate 
based on the participant's business needs. While the Exchange believes 
that some firms will want to restrict self-match prevention to trading 
against interest from the same MPID or same port--i.e., as implemented 
today--the Exchange believes that other firms will find it helpful to 
be able to configure self-match prevention to apply at the OrgId level 
so that they are protected regardless of which MPID the order or quote 
originated from.
Implementation Date
    The Exchange intends to introduce this new functionality no later 
than the First Quarter of 2023. In any event, the Exchange will issue 
an Equities Trader Alert to provide notification of the change and 
relevant date prior to introducing the new functionality.
2. Statutory Basis
    The Exchange believes that its proposal is consistent with Section 
6(b) of the Act,\7\ in general, and furthers the objectives of Section 
6(b)(5) of the Act,\8\ 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.
---------------------------------------------------------------------------

    \7\ 15 U.S.C. 78f(b).
    \8\ 15 U.S.C. 78f(b)(5).
---------------------------------------------------------------------------

    The Exchange believes that the proposed rule change is consistent 
with the protection of investors and the public interest as it is 
designed to provide market participants with additional flexibility 
with respect to how to implement self-trade protections provided by 
anti-internalization functionality. Currently, market participants are 
provided optional functionality that (1) prevents quotes and orders 
from one MPID from trading with quotes and orders from the same MPID, 
or (2) prevents quotes and orders entered through a specific order 
entry port from trading with quotes and orders entered though the same 
order entry port (in the case of market participants using the OUCH 
order entry protocol). This functionality allows participants to better 
manage their order flow and prevent undesirable executions where the 
participant, using the same MPID or same port, would be on both sides 
of the trade. While this functionality is helpful, the Exchange 
proposes to expand the protections to provide participants with the 
option not to trade with quotes and orders entered by different MPIDs 
under Common Ownership. The Exchange would continue to provide the 
option to opt out of the self-match prevention. In addition, the 
Exchange would continue to provide the option to use the current 
functionality to prevent self-trades on a per MPID or per port basis. 
The proposed rule change would offer a new option for participants 
opting-in to the self-match prevention to prevent undesirable 
executions across different MPIDs under the same Common Ownership. The 
Exchange believes that flexibility to apply anti-internalization 
functionality at the OrgId level would be useful to participants. The 
Exchange believes that the proposed rule change is designed to promote 
just and equitable principles of trade and will remove impediments to 
and perfect the mechanisms of a free and open market as it will further 
enhance self-trade protections provided to market participants. This 
functionality does not relieve or otherwise modify the duty of best 
execution owed to orders received from public customers.

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 not necessary or appropriate in 
furtherance of the purposes of the Act. The proposed rule change is 
designed to enhance self-match prevention functionality provided to the 
Exchange's participants and will benefit participants that wish to 
protect their quotes and orders against trading with other quotes and 
orders within the same

[[Page 65633]]

OrgId, rather than the more limited MPID or port standard applied 
today. The new functionality is also completely voluntary, and members 
that wish to use the current functionality (or opt out altogether) can 
also continue to do so. The Exchange does not believe that providing 
more flexibility to participants will have any significant impact on 
competition. In fact, the Exchange believes that the proposed rule 
change is evidence of the competitive environment where exchanges must 
continually improve their offerings to maintain competitive standing.

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

    No written comments were either solicited or received.

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

    Because the foregoing proposed rule change does not: (i) 
significantly affect the protection of investors or the public 
interest; (ii) impose any significant burden on competition; and (iii) 
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)(iii) of the Act \9\ and 
subparagraph (f)(6) of Rule 19b-4 thereunder.\10\
---------------------------------------------------------------------------

    \9\ 15 U.S.C. 78s(b)(3)(A)(iii).
    \10\ 17 CFR 240.19b-4(f)(6). In addition, Rule 19b-4(f)(6) 
requires a self-regulatory organization to give the Commission 
written notice of its intent to file the proposed rule change at 
least five business days prior to the date of filing of the proposed 
rule change, or such shorter time as designated by the Commission. 
The Exchange has satisfied this requirement.
---------------------------------------------------------------------------

    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 shall institute proceedings to 
determine whether the proposed rule should be approved or disapproved.
