Self-Regulatory Organizations; 24X National Exchange LLC; Notice 
of Filing of a Proposed Rule Change Regarding the Regular Hours Only 
Instruction

September 5, 2025.
    Pursuant to Section 19(b)(1) of the Securities Exchange Act of 1934 
(the ``Exchange Act'' or the ``Act'') \1\ and Rule 19b-4 thereunder,\2\ 
notice is hereby given that on August 27, 2025, 24X National Exchange 
LLC (``24X'' or the ``Exchange'') filed with the Securities

[[Page 43667]]

and Exchange Commission (``SEC'' or ``Commission'') the proposed rule 
change as described in Items I, II, and III below, which Items have 
been prepared by the Exchange. The Exchange filed the proposal as a 
``non-controversial'' proposed rule change pursuant to Section 
19(b)(3)(A)(iii) of the Act \3\ and Rule 19b-4(f)(6) thereunder.\4\ The 
Commission is publishing this notice to solicit comments on the 
proposed rule change from interested persons.

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

    The Exchange is filing with the Commission a proposed rule change 
to require that any order with a time-in-force (``TIF'') instruction of 
Regular Hours Only (``RHO'') \5\ that is entered into the System \6\ 
before the opening or after the closing of the Core Market Session \7\ 
be rejected. This change would conform the treatment of orders with an 
RHO instruction with the treatment of such orders on other national 
securities exchanges. The text of the proposed rule change is also 
available on the Exchange's website (<a href="https://equities.24exchange.com">https://equities.24exchange.com</a>) 
and at the Exchange's principal office.
---------------------------------------------------------------------------

    \5\ See 24X Rule 11.6(o)(2).
    \6\ The term ``System'' means ``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. See 24X Rule 1.5(hh).
    \7\ The term ``Core Market Session'' means ``the time between 
9:30 a.m. and 4:00 p.m. Eastern Time each U.S. Business Day.'' See 
24X Rule 1.5(l).
---------------------------------------------------------------------------

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
    Under the 24X Rules, orders may be submitted to the Exchange with a 
TIF instruction of RHO, which is an ``instruction the User may attach 
to an order stating any order to buy or sell is designated for 
execution during the Core Market Session, and, if not executed, expires 
at the end of the Core Market Session.'' \8\ 24X permits RHO Orders to 
be entered into the System at any time. Specifically, 24X Rule 
11.6(o)(2) states that
---------------------------------------------------------------------------

    \8\ See 24X Rule 11.6(o)(2).

    RHO Orders may be entered into the System at any time, but no 
RHO Order may be executed outside of the Core Market Session. For 
RHO Orders entered outside the Core Market Session, or during the 
Core Market Session but prior to the commencement of trading, 
trading for such RHO Orders will commence once the security has 
begun trading on the primary listing market on or after 9:30:00 a.m. 
---------------------------------------------------------------------------
Eastern Time.

24X proposes to revise its rules to reject any RHO Order that is 
entered into the System before the opening or after the closing of the 
Core Market Session.
    To implement the change in the treatment of RHO Orders, 24X 
proposes to amend Rule 11.6(o)(2). Specifically, 24X proposes to delete 
from 24X Rule 11.6(o)(2) the following language:

    RHO Orders may be entered into the System at any time, but no 
RHO Order may be executed outside of the Core Market Session. For 
RHO Orders entered outside the Core Market Session, or during the 
Core Market Session but prior to the commencement of trading, 
trading for such RHO Orders will commence once the security has 
begun trading on the primary listing market on or after 9:30:00 a.m. 
Eastern Time.

24X proposes to replace this language with the following: ``Any order 
with a TIF instruction of RHO entered into the System before the 
opening or after the closing of the Core Market Session will be 
rejected.'' With this change, the definition of an RHO instruction in 
24X Rule 11.6(o)(2) would conform with the definition of an RHO 
instruction as set forth in the rules of other national securities 
exchanges.\9\
---------------------------------------------------------------------------

    \9\ See, e.g., MEMX Rule 11.6(o)(5); LTSE 11.180(o)(5).
---------------------------------------------------------------------------

    Correspondingly, 24X proposes to amend the definition of ``24X 
Trading Day'' in 24X Rule 1.5(b) to conform the discussion of RHO 
Orders in the definition of 24X Trading Day with the proposed revised 
description of an RHO Order in 24X Rule 11.6(o)(2). 24X Rule 1.5(b) 
discusses the treatment of RHO Orders entered outside the Core Market 
Session, or during the Core Market Session but prior to the 
commencement of trading. Specifically, 24X Rule 1.5(b) states, in 
relevant part, that

    For RHO Orders entered outside the Core Market Session, or 
during the Core Market Session but prior to the commencement of 
trading, trading for such RHO Orders will commence once the security 
has begun trading on the primary listing market on or after 9:30:00 
a.m. Eastern Time; for all orders eligible to trade in the Core 
Market Session other than such RHO Orders, trading will be 
continuous in the Core Market Session, with no pause in trading 
related to the commencement of trading on the primary listing 
market.

24X proposes to delete this language from 24X Rule 1.5(b) because 24X 
proposes to revise its Rules to reject RHO Orders entered into the 
System before the opening or after the closing of the Core Market 
Session.\10\ This change would conform the definition of 24X Trading 
Day with the proposed revised definition of an RHO instruction in 24X 
Rule 11.6(o)(2).
---------------------------------------------------------------------------

    \10\ 24X also proposes to delete the phrase ``including the 
pause in trading described in the next sentence'' from 24X Rule 
1.5(b) as the referenced ``next sentence'' is proposed to be deleted 
from 24X Rule 1.15(b).
---------------------------------------------------------------------------

2. Statutory Basis
    The Exchange believes the proposed rule change is consistent with 
the Exchange Act and the rules and regulations thereunder applicable to 
the Exchange and, in particular, the requirements of Section 6(b) of 
the Act.\11\ Specifically, the Exchange believes the proposed rule 
change is consistent with the Section 6(b)(5) \12\ 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) \13\ requirement that the rules of an exchange not be designed 
to permit unfair discrimination between customers, issuers, brokers, or 
dealers.
---------------------------------------------------------------------------

    \11\ 15 U.S.C. 78f(b).
    \12\ 15 U.S.C. 78f(b)(5).
    \13\ Id.
---------------------------------------------------------------------------

    The Exchange believes the proposed rule change will remove 
impediments to and perfect the mechanism of a free and open market and 
a national market system. The proposal to reject any RHO Order that is 
entered into the System before the opening or after the closing of the 
Core Market Session is consistent

[[Page 43668]]

with the rules of other national securities exchanges that have RHO 
Orders. As such, the proposed rule change would not impose a burden 
competition as it would allow the Exchange to operate in the same 
manner as other national securities exchanges currently operate with 
regard to RHO Orders. Thus, the proposed rule change to revise the 
treatment of RHO Orders on the Exchange is not novel or unique. The 
Commission has previously determined that the proposed revised 
treatment of RHO Orders complies with the requirements of the Exchange 
Act.
    Moreover, the proposal would remove impediments to and perfect the 
mechanism of a free and open market and a national market system, and, 
in general, protect investors and the public interest by allowing 
investors to trade on the Exchange in the same manner that investors 
trade on other national securities exchanges without making changes to 
their order handling processes.
    Furthermore, the proposed rule change further removes impediments 
to a free and open market and does not unfairly discriminate among 
market participants, as all Members of the Exchange will be able, but 
not be required, to make use of the RHO Orders as described in this 
proposed rule change.

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

    The Exchange does not believe that the proposed rule change will 
result in any burden on competition that is not necessary or 
appropriate in furtherance of the purposes of the Act. As discussed 
above, the proposal to reject any RHO Order that is entered into the 
System before the opening or after the closing of the Core Market 
Session is consistent with the rules of other national securities 
exchanges that have RHO Orders. As such, the proposed rule change would 
promote competition by allowing the Exchange to operate in the same 
manner as other national securities exchanges currently operate with 
regard to RHO Orders and allow investors to trade on the Exchange in a 
manner similar to trading on other national securities exchanges with 
regard to RHO Orders. The Commission has previously determined that the 
proposed revised treatment of RHO Orders will not result in any burden 
on competition that is not necessary or appropriate in furtherance of 
the purposes of the Act in approving comparable rules of other national 
securities exchanges.

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 \14\ and 
Rule 19b-4(f)(6) \15\ 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.
---------------------------------------------------------------------------

    \14\ 15 U.S.C. 78s(b)(3)(A).
    \15\ 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, along 
with a brief description and text of 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.
---------------------------------------------------------------------------
