###### Securities and Exchange Commission

          - [Release No. 34-101103; File No. SR-NYSECHX-2024-29]

                    Pursuant to Section 19(b)(1) [1]                                          of the Securities Exchange Act of 1934 (“Act”) [2]                                          and Rule 19b-4 thereunder,[3]                                          notice is hereby given that, on September 9, 2024, the NYSE Chicago, Inc. (“NYSE Chicago” or the “Exchange”) filed with the Securities and Exchange Commission (the “Commission”) the proposed rule change as described in Items I and II below, which Items have been prepared by the self-regulatory organization. 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 proposes to amend Rule 7.31 regarding the Minimum Trade Size Modifier. The proposed rule change is available on the Exchange's website at                     *www.nyse.com,*                     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 self-regulatory organization 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 those 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 parts of such statements.                          ( print page 78407)    

### A. Self-Regulatory Organization's Statement of the Purpose of, and the Statutory Basis for, the Proposed Rule Change

#### 1. Purpose

The Exchange proposes to amend Rule 7.31 regarding the Minimum Trade Size (“MTS”) Modifier.

                    Rule 7.31(i)(3) provides that a Limit IOC Order, Non-Displayed Limit Order, MPL Order, or Tracking Order may be designated with an MTS Modifier. Rule 7.31(i)(3)(A) currently provides that an MTS must be a minimum of a round lot and that an order with an MTS Modifier will be rejected if the MTS is less than a round lot or if the MTS is larger than the size of the order. The Exchange proposes to amend Rule 7.31(i)(3)(A) to provide that an MTS may be an odd lot quantity and thus proposes to eliminate rule text currently providing that an MTS must be a minimum of a round lot and that an order with an MTS of less than one round lot would be rejected. The Exchange believes that restricting the use of the MTS Modifier to round lot sizes only is unnecessary and that providing Participants with the option to use the MTS Modifier with an odd lot quantity could increase liquidity and enhance opportunities for order execution on the Exchange. The Exchange notes that permitting odd-lot order quantities is not novel on the Exchange or other equity exchanges and believes that this proposed change is consistent with other equity exchanges' approaches to the use of instructions similar to the MTS Modifier.[4] 

                    The Exchange also proposes to amend Rule 7.31(i)(3) to include the non-displayed ALO Order as an order type that could be designated with an MTS Modifier. This clarifying change is intended only to reflect current behavior, by providing a complete list of the order types that may be designated with an MTS Modifier. The Exchange notes that the inclusion of the non-displayed ALO Order [5]                                          as an order type that may be designated with an MTS Modifier is consistent with the existing use of the MTS Modifier with non-displayed order types such as Non-Displayed Limit Orders and MPL Orders (including MPL-ALO Orders). Moreover, although the non-displayed ALO Order is a Limit Order that is non-displayed, the Exchange believes that specifically including the non-displayed ALO Order in the text of Rule 7.31(i)(3) would reduce ambiguity as to the order types that may be designated with an MTS Modifier.                

Because of the technology changes associated with this proposed rule change, the Exchange will announce the implementation date by Trader Update, which, subject to effectiveness of this proposed rule change, will be no later than in the fourth quarter of 2024.

#### 2. Statutory Basis

                    The proposed rule change is consistent with Section 6(b) of the Act,[6]                                          in general, and furthers the objectives of Section 6(b)(5),[7]                                          in particular, because 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.                

                    The Exchange believes that 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 because it would provide Participants with the option to use the MTS Modifier with odd lot quantities, which could encourage order flow to the Exchange and promote opportunities for order execution on the Exchange, to the benefit of all market participants. The proposed change would also clarify that the MTS Modifier may be used in conjunction with non-displayed ALO Orders, thereby removing impediments to, and perfecting the mechanism of, a free and open market and a national market system by updating Exchange rules to ensure that they reflect the current availability of the MTS Modifier and promoting consistency and specificity in Exchange rules as to the use of such modifier with non-displayed order types. The Exchange notes that the proposed change would not otherwise impact the operation of the MTS Modifier as provided under current Exchange rules. The Exchange also believes that the proposed change would align Exchange rules with the use of instructions similar to the MTS Modifier on other equity exchanges, thereby removing impediments to, and perfecting the mechanism of, a free and open market and a national market system.[8] 

### 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 proposed change would allow the optional MTS Modifier to be used with an odd lot quantity and accurately reflect the order types that may be designated with an MTS Modifier. The Exchange believes that the proposed change would promote competition among exchanges by offering Participants options available on other equity exchanges and, to the extent the proposed change would increase opportunities for order execution, promote competition by making the Exchange a more attractive venue for order flow and enhancing market quality for all market participants.

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

No written comments were solicited or received with respect to the proposed rule change.

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

                    The Exchange has filed the proposed rule change pursuant to Section 19(b)(3)(A)(iii) of the Act [9]                                          and Rule 19b-4(f)(6) thereunder.[10]                                          Because the 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 prior to 30 days from the date on which it was filed, or such shorter time as the Commission may designate, if consistent with the protection of investors and the public interest, the proposed rule change has become effective pursuant to Section                           ( print page 78408)                        19(b)(3)(A)(iii) of the Act [11]                                          and Rule 19b-4(f)(6)(iii) thereunder.[12] 

                    A proposed rule change filed under Rule 19b-4(f)(6) [13]                                          normally does not become operative prior to 30 days after the date of the filing. However, pursuant to Rule 19b4(f)(6)(iii),[14]                                          the Commission may designate a shorter time if such action is consistent with the protection of investors and the public interest. The Exchange has asked the Commission to waive the 30-day operative delay so that the proposal may take effect as soon as the technology associated with the proposed change is available, which is anticipated to be less than 30 days from the date of this filing. The Commission believes that waiver of the operative delay is consistent with the protection of investors and the public interest because the proposal raises no novel issues and would allow use of the MTS Modifier with odd lot quantities without delay and promote clarity in Exchange rules as to the order types that may be designated with an MTS Modifier. Accordingly, the Commission hereby waives the 30-day operative delay and designates the proposal operative upon filing.[15] 

                    At any time within 60 days of the filing of such 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 under Section 19(b)(2)(B) [16]                                          of the Act to determine whether the proposed rule change should be approved or disapproved.
