1. [Release No. 34-105238; File No. SR-MRX-2026-15] April 14, 2026. Pursuant to Section 19(b)(1) of the Securities Exchange Act of 1934 (“Act”), [1 ] and Rule 19b-4 thereunder, [2 ] notice is hereby given that on April 1, 2026, Nasdaq MRX, LLC (“MRX” or “Exchange”) filed with the Securities 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 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 the quarterly review of Professional Orders. [3 ]

The text of the proposed rule change is available on the Exchange's website at https://listingcenter.nasdaq.com/​rulebook/​mrx/​rulefilings, 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 the quarterly review of Professional Orders. Today, orders for any Priority Customer [4 ] that average more than 390 orders per day during any month of a calendar quarter must be represented as Professional orders for the next calendar quarter. [5 ] In order to properly represent orders entered on the Exchange, Members [6 ] are required currently to review their Priority Customers' activity and, on at least a quarterly basis, designate orders as Priority Customer orders or Professional orders. [7 ] Specifically, Members are required to conduct a quarterly review and make any appropriate changes to the way in which they are representing orders within five days after the end of each calendar quarter. [8 ] While Members are required to designate accounts on a quarterly basis, if during a quarter the Exchange identifies a customer for which orders are being represented as Priority Customer Orders but that has averaged more than 390 orders per day during a month, the Exchange must notify the Member and the Member is required to change the manner in which it is representing the customer's orders within five days. [9 ]

Proposal

At this time, the Exchange proposes to shorten the quarterly review and designation to a monthly review. The Exchange proposes to state at Options 1, Section 1(a)(39)(b) that orders for any customer that had an average of more than 390 orders per day during any calendar month must be represented as Professional orders for the next calendar month.

As noted, currently, each Member is required to monitor Priority Customer orders to determine if the Priority Customer has averaged more than 390 orders per day during a month. Determining whether a Priority Customer has executed more than 390 orders per day during a month requires computing a daily average. As such, Members should be performing the workflow necessary to designate orders on a daily basis. Therefore, the proposal does not amend the current workflow, rather, the proposal amends the timeframe to change the manner in which the customer's order is being represented from five days after the end of each calendar quarter to five days after the end of each calendar month.

The Exchange does not believe that this amendment is a significant departure from the current rule, nor does it impose any burden on any Member because each broker-dealer is required currently to perform the necessary calculation daily to arrive at the requisite average. Further, in addition to the calculation, broker-dealers are subject to know-your-customer and suitability requirements under FINRA Rules 2090 (Know Your Customer) and 2111 (Suitability) and would need to consider whether a customer meets the Professional designation for purposes of determining best execution and making appropriate recommendations. The Exchange notes that the trading behavior of a Priority Customer can be distinguished from that of a Professional which is the purpose of the separate designations. Finally, some Members currently designate a Priority Customer that has averaged more than 390 orders per day during a month as a Professional on a more expedited basis, not waiting until five days after the quarter.

The Exchange believes that a calendar month is a sufficient time period to determine whether the activity of a customer meets the criteria for a Professional order. The Exchange believes that the shortened time period will ensure that the spirit of the designation of Professional order is met in that Members will make any appropriate changes to the way in which they are representing orders in a 30-day timeframe as opposed to a 90-day timeframe, thereby ensuring the ( printed page 20730) designation is applied in a more expeditious manner.

The Exchange continues to believe that identifying Professional orders based upon the average number of orders entered in qualified accounts is an appropriate and objective approach to reasonably distinguish such persons and entities from retail investors or market participants.

Technical Amendment

The Exchange proposes to reserve Options 4D. Another Nasdaq affiliated exchange proposes rules at Options 4D. Other Nasdaq affiliated exchanges have a rule or proposed rule in this corresponding section. The reserved section is intended to harmonize the structure of MRX's rules to those of other Nasdaq affiliated exchanges. The Exchange proposes that this amendment be operative 30 days from the date of filing.

Implementation

The Exchange proposes implementing this rule change on July 1, 2026, except for the technical amendments which should become operative 30 days after the date of the filing. The Exchange will issue an Options Trader Alert to provide notice to Members of the proposed change.

2. Statutory Basis

The Exchange believes that the proposed rule change is consistent with Section 6(b) of the Act, [10 ] in general, and furthers the objectives of Section 6(b)(5) of the Act, [11 ] 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.

The Exchange's proposal to shorten the quarterly look-back to a monthly look-back is consistent with the Act because it will ensure that the spirit of the designation of Professional order continues to be met, only on a more expedited basis—removing a potential delay of two months before affecting a change in the designation. The Exchange believes that this amendment will remove impediments to and perfect the mechanism of a free and open market and a national market system by promoting the consistent application of its rules and shortening the timeframe to change the designation for all Members while continuing to provide a sufficient time period to determine whether the activity of a customer meets the criteria for a Professional order. Further, the Exchange believes that the shortened time period will continue to promote consistency in the treatment of orders as Professional orders while also preventing members with high volume from receiving benefits reserved for Priority Customer orders.

As noted, currently, each Member is required to monitor Priority Customer orders to determine if the Priority Customer has averaged more than 390 orders per day during a month. Determining whether a Priority Customer has executed more than 390 orders per day during a month requires computing a daily average. As such, Members should be performing the workflow necessary to designate orders on a daily basis. Therefore, the proposal does not amend the current workflow, rather, the proposal amends the timeframe to change the manner in which the customer's order is being represented from five days after the end of each calendar quarter to five days after the end of each calendar month.

The Exchange does not believe that this amendment is a significant departure from the current rule, nor does it impose any burden on any Member because each broker-dealer is required currently to perform the necessary calculation daily to arrive at the requisite average. Further, in addition to the calculation, broker-dealers are subject to know-your-customer and suitability requirements under FINRA Rules 2090 (Know Your Customer) and 2111 (Suitability) and would need to consider whether a customer meets the Professional designation for purposes of determining best execution and making appropriate recommendations. Finally, some Members currently designate a Priority Customer that has averaged more than 390 orders per day during a month as a Professional on a more expedited basis, not waiting until five days after the quarter.

The Exchange notes that the trading behavior of a Priority Customer can be distinguished from that of a Professional which is the purpose of the separate designations. The Exchange continues to believe that identifying Professional orders based upon the average number of orders entered in qualified accounts is an appropriately objective approach to reasonably distinguish such persons and entities from retail investors or market participants. Priority is one of the marketplace advantages provided to Priority Customer orders on the Exchange. Priority Customer orders are given execution priority over non-Customer orders and quotations of market makers at the same price. Another marketplace advantage afforded to Priority Customer orders on the Exchange is that members are generally not assessed transaction fees or are assessed lower fees for the execution of Priority Customer orders. The purpose of these marketplace advantages is to attract retail order flow to the Exchange by leveling the playing field for retail investors over market Professionals. This proposal will continue to provide Priority Customer accounts with marketplace advantages and distinguish those accounts non-Professional retail investors from the Professionals accounts. The Exchange notes that some non-broker-dealer individuals and entities have access to information and technology that enables them to Professionally trade listed options in the same manner as a broker or dealer in securities

Technical Amendment

Reserving Options 4D is a non-substantive amendment.

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.

Specifically, the Exchange does not believe that the proposed rule change will impose any burden on intra-market competition because, today, each Member is required to monitor Priority Customer orders to determine if the Priority Customer has averaged more than 390 orders per day during a month. Determining whether a Priority Customer has executed more than 390 orders per day during a month requires computing a daily average. As such, Members should be performing the workflow necessary to designate orders on a daily basis. Therefore, the proposal does not amend the current workflow, rather, the proposal amends the timeframe to change the manner in which the customer's order is being represented from five days after the end of each calendar quarter to five days after the end of each calendar month.

The Exchange does not believe that this amendment is a significant departure from the current rule, nor does it impose any burden on any Member because each broker-dealer is required currently to perform the necessary calculation daily to arrive at the requisite average. Further, in addition to the calculation, broker-dealers are subject to know-your-customer and suitability requirements under FINRA Rules 2090 (Know Your ( printed page 20731) Customer) and 2111 (Suitability) and would need to consider whether a customer meets the Professional designation for purposes of determining best execution and making appropriate recommendations. Finally, some Members currently designate a Priority Customer that has averaged more than 390 orders per day during a month as a Professional on a more expedited basis, not waiting until five days after the quarter.

The Exchange notes that the trading behavior of a Priority Customer can be distinguished from that of a Professional which is the purpose of the separate designations.

Further, the designation of Professional orders would not result in any different treatment of such orders for purposes of compliance with the Exchange's Rules. Priority Customers have been granted certain priority over other non-broker-dealer individuals and entities that have access to information and technology that enables them to Professionally trade listed options in the same manner as a broker or dealer in securities. Further, the Priority Customer designation allows the Exchange to attract order flow or create more competitive markets.

Also, the Exchange does not believe that the proposed rule change will impose any burden on inter-market competition because other exchanges are expected to adopt similar rules.

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 [12 ] and subparagraph (f)(6) of Rule 19b-4 thereunder. [13 ]

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.
