The Commission is publishing this notice to solicit comments on the proposed rule change from interested persons. <FTNT> <SU>1</SU>  15 U.S.C. 78s(b)(1). </FTNT> <FTNT> <SU>2</SU>  17 CFR 240.19b-4. </FTNT> <HD SOURCE="HD1">I. Self-Regulatory Organization's Statement of the Terms of Substance of the Proposed Rule Change</HD> The Exchange proposes to make a number of minor, non-substantive edits to the Exchange's Rulebook. The text of the proposed rule change is available on the Exchange's website at <E T="03">https://www.miaxglobal.com/markets/us-options/all-options-exchanges/rule-filings,</E> at MIAX's principal office. <HD SOURCE="HD1">II. Self-Regulatory Organization's Statement of the Purpose of, and Statutory Basis for, the Proposed Rule Change</HD> 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. <HD SOURCE="HD2">A. Self-Regulatory Organization's Statement of the Purpose of, and Statutory Basis for, the Proposed Rule Change</HD> <HD SOURCE="HD3">1. Purpose</HD> <HD SOURCE="HD3">Proposal To Remove the Definition of WAIT Orders</HD> The Exchange proposes to amend Exchange Rule 516(d) to remove the definition of WAIT Orders. Currently, Exchange Rule 516(d) provides that “WAIT” shall mean for orders so designated, that upon entry into the System, the order is held for one second without processing for potential display and/or execution. After one second, the order is processed for potential display and/or execution in accordance with all order entry instructions as determined by the entering party. The Exchange notes that WAIT Orders have never been implemented and are not currently in use. The Exchange proposes to remove the definition of WAIT Orders and then insert “Reserved” so as to keep the remainder of the Rulebook as currently formatted. The purpose of proposed rule change is to remove obsolete rule text and provide greater clarity to Members  <SU>3</SU> <FTREF/> and the public regarding the Exchange's offerings and Rulebook. In the event that the Exchange desires to offer WAIT Orders in the future, the Exchange will file a rule change with the U.S. Securities and Exchange Commission (the “Commission”) to adopt rules to offer WAIT Orders. <FTNT> <SU>3</SU>  The term “Member” means an individual or organization approved to exercise the trading rights associated with a Trading Permit. Members are deemed “members” under the Exchange Act. <E T="03">See</E> Exchange Rule 100. </FTNT> <HD SOURCE="HD3">Proposal To Update Citations to Rule 600(b) of Regulation NMS</HD> The Exchange proposes to update citations to Rule 600(b) of Regulation NMS in Interpretation and Policy .01 to Exchange Rule 518, Complex Orders, Exchange Rule 530, Limit Up-Limit Down, and Exchange Rule 1701, Consolidated Audit Trail Compliance Rule—Definitions. In 2024, the Commission amended Regulation NMS under the Act to update the rule that requires disclosures for order executions in national market system (“NMS”) stocks. <SU>4</SU> <FTREF/> As part of that initiative, the Commission adopted new definitions in Rule 600(b) of Regulation NMS and renumbered the remaining definitions, including the definitions of Regular Trading Hours (formerly Rule 600(b)(77)), Listed Option (formerly Rule 600(b)(43)), NMS Stock (formerly Rule 600(b)(55)), and Trading Center (formerly Rule 600(b)(95)). <FTNT> <SU>4</SU>   <E T="03">See</E> Securities Exchange Act Release No. 99679, 89 FR 26428 (April 15, 2024) (S7-29-22). </FTNT> The Exchange accordingly proposes to update the relevant citations to Rule 600(b) in its rules as follows: • The citations to the definition of NMS Stock in Interpretation and Policy .01(b) to Exchange Rules 518 and 1701(qq) would be changed to Rule 600(b)(65) of Regulation NMS. • The citations to the definition of Trading Center in Interpretation and Policy .01(b) to Exchange Rule 518 would be changed to Rule 600(b)(106) of Regulation NMS. • The citation to the definition of Regular Trading Hours in Exchange Rule 530(a) would be changed to Rule 600(b)(88) of Regulation NMS. • The citation to the definition of Listed Option in Exchange Rule 1701(y) would be changed to Rule 600(b)(52) of Regulation NMS. <HD SOURCE="HD3">Proposal To Amend Exchange Rule 1014(d)(5)</HD> The Exchange proposes to amend Exchange Rule 1014(d)(5) to make a minor, non-substantive edit to provide accuracy and precision within the rule text. Currently, the table in Exchange Rule 1014(d)(5) provides the number of violations of Exchange Rule 520(b) regarding limitations on orders entered into the System by Electronic Exchange Members  <SU>5</SU> <FTREF/> and the applicable sanctions that may be imposed by the Exchange. In particular, the fifth row of the table provides that if an Electronic Exchange Members has sixteen (16) or twenty (20) violations within one calendar year, it may be subject to a $2,000 fine. The Exchange now proposes to amend the fifth row of the table by replacing “16 or 20” with “16 to 20” under the heading of “Number of Violations Within One Calendar Year”. The proposed rule change is to correct an inadvertent drafting error in the original rule text. The proposed rule change will provide clarity by accurately reflecting the intended range of violations. Specifically, violations numbering from sixteen (16) to twenty (20) within a calendar year are subject to a fine of $2,000. The proposed rule change is consistent with the format used in the surrounding rows, which clearly present ranges of violations. The purpose of the proposed rule change is to provide accuracy and precision within the rule text. <FTNT> <SU>5</SU>  The term “Electronic Exchange Member” or “EEM” means the holder of a Trading Permit who is not a Market Maker. Electronic Exchange Members are deemed “members” under the Exchange Act. <E T="03">See</E> Exchange Rule 100. </FTNT> <HD SOURCE="HD3">Proposal To Amend Exchange Rule 1308</HD> The Exchange proposes to amend Exchange Rule 1308(a) to remove an extra hyphen in the heading. Accordingly, with the proposed rule change, Exchange Rule 1308(a) will read as follows: (a) Duty to Supervise—Non-Member Accounts. The general partners or directors of each Member that conducts a non-member customer business shall provide for appropriate supervisory control and shall designate a general partner or executive officer, who shall be identified to the Exchange, to assume overall authority and responsibility for internal supervision and control of the organization and compliance with securities laws and regulations. This person, who may be the same individual designated pursuant to substantially similar New York Stock Exchange or FINRA rules, shall: In addition, the Exchange proposes to remove Interpretation and Policy .01 to Exchange Rule 1308. On March 18, 2025, the Exchange filed its proposal (SR-MIAX-2025-12) to amend Exchange Rule 1308 to align the annual obligations for Members with industry standard approaches. <SU>6</SU> <FTREF/> Specifically, the Exchange amended Exchange Rule 1308(g) to require that the designated supervisory personnel must submit to the Member's senior management, instead of the Exchange, no less than annually, a report detailing each Member's system of supervisory controls, the summary of the test results and significant identified exceptions, and any additional or amended supervisory procedures created in response to the test results. Currently, Interpretation and Policy .01 to Exchange Rule 1308 provides that Members required to file an annual report under paragraph (g) of Exchange Rule 1308 must file such report electronically with the Exchange by utilizing the system or software prescribed by the Exchange which will be announced via Regulatory Circular. Since Members are no longer required to submit such report to the Exchange, the Exchange proposes to remove Interpretation and Policy .01 to Exchange Rule 1308. The purpose of the proposed change is to remove obsolete text in the Rulebook and provide greater clarity to Members and the public regarding the Exchange's Rulebook. <FTNT> <SU>6</SU>   <E T="03">See</E> Securities Exchange Act Release No. 102722 (March 25, 2025), 90 FR 14290 (March 31, 2025) (SR-MIAX-2025-12) (Notice of Filing and Immediate Effectiveness of a Proposed Rule Change To Amend Exchange Rule 1308, Supervision of Accounts). </FTNT> The Exchange notes that Exchange Rule 1308 as proposed to be amended by this filing, is incorporated by reference into the rulebooks of the Exchange's affiliates, MIAX PEARL, LLC (“MIAX Pearl”), MIAX Emerald, LLC (“MIAX Emerald”), and MIAX Sapphire, LLC (“MIAX Sapphire”).
