          - [Release No. 34-92229; File No. SR-MRX-2021-07]

                    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 June 15, 2021, Nasdaq MRX, LLC (“MRX” or “Exchange”) filed with the Securities and Exchange Commission (“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 Options 2, Section 4, Obligations of Market Makers. The Exchange also proposes to add a new Options 4C.

                    The text of the proposed rule change is available on the Exchange's website at                     *https://listingcenter.nasdaq.com/​rulebook/​MRX/​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 Exchange proposes to amend Options 2, Section 4, Obligations of Market Makers. The Exchange also proposes to add a new Options 4C.

#### Options 2, Section 4(a)

                    The Exchange proposes to remove the following rule text from Options 2, Section 4(a), which has been in place since MRX's inception: [3] 

. . . Ordinarily, Market Makers are expected to:

(1) Refrain from purchasing a call option or a put option at a price more than $0.25 below parity, although a larger amount may be appropriate considering the particular market conditions. In the case of calls, parity is measured by the bid in the underlying security, and in the case of puts, parity is measured by the offer in the underlying security.

(2) The $0.25 amount above may be increased, or the provisions of this Rule may be waived, by the Exchange on a series-by-series basis.

                    This proposed rule text also previously existed on Cboe Exchange, Inc. within prior Rule 8.7 [4]                                          and was removed from Cboe's Rulebook in 2019.[5]                                          The Exchange likewise desires to remove this restriction on Market Makers which does not exist on Cboe or other Nasdaq affiliated markets.[6]                                          The proposed rule text is currently waived on MRX pursuant to Options 2, Section 4(a)(2). The Exchange proposes to remove this rule text from Options 2, Section 4 as the Exchange does not desire to enforce this provision in the future. The Exchange believes that this market maker provision is no longer necessary. Today, MRX incentivizes Market Makers through allocation [7]                                          to quote tightly in their assigned options series. Primary Market Makers and Competitive Market Makers also have other obligations with respect to market making [8]                                          in addition to other quoting                           ( print page 34078)                        obligations [9]                                          that they must abide by when quoting on MRX. Also, since the adoption of the rule, the Exchange has adopted the obvious error rule [10]                                          which permits the Exchange to review a transaction as potentially erroneous based on a theoretical price. Also, MRX orders are subject to trade-through compliance, thereby limiting the prices at which orders may execute.[11]                                          Market Makers are relied upon to provide liquidity on MRX, which benefits other Members who have the opportunity to interact with the order flow. The Exchange believes that the obligation to refrain from purchasing a call option or a put option at a price more than $0.25 below parity places yet another obligation on MRX Market Makers that is not required on Cboe or other Nasdaq markets. The Exchange believes that this additional obligation is not necessary to maintain fair and orderly markets and notes the Exchange has waived this obligation.                

#### Bid/Ask Differentials

The Exchange proposes to amend Options 2, Section 4(b)(4) and Options 4A, Section 12(b)(i) to centralize the bid/ask differentials. Specifically, the Exchange proposes to state within new Options 2, Section 4(b)(4)(iii) that,

Bid/ask differentials shall not apply to any options series until the time to expiration is less than nine (9) months for equity options and exchange-traded products. Bid/ask differentials shall not apply to any options series until the time to expiration is less than twelve (12) months for index options.

                    Currently, MRX Options 4 and Options 4A rules are incorporated by reference to Nasdaq ISE, LLC (“ISE”). The Exchange recently filed a rule change [12]                                          to amend ISE Options 4 and Options 4A rules to relocate text concerning bid/ask differentials for long-term option series from ISE Options 4, Section 8(a) [13]                                          and ISE Options 4A, Section 12(b)(i).[14]                                          The ISE Rule Change added citations to Options 2, Section 4(b)(4)(iii) to ISE Options 4, Section 8(a) and ISE Options 4A, Section 12(b)(i). The ISE Rule Change indicated that ISE believes relocating the bid/ask differentials to Options 2, Section 4(b)(4)(iii) will provide Primary Market Makers and Competitive Market Makers with centralized information regarding their bid/ask differential requirements.                

#### Business Continuity and Disaster Recovery Plan

                    The Exchange proposes to relocate Supplementary Material .02 to Options 2, Section 4, concerning business continuity and disaster recovery plans, to General 2, Section 12, which is currently reserved. The Exchange proposes to title General 2, Section 12 as “Business Continuity and Disaster Recovery Plan Testing Requirements for Members Pursuant to Regulation SCI.” The rule text is being relocated without change. The Exchange proposes to relocate this rule text to harmonize MRX's rules with that of Nasdaq PHLX LLC (“Phlx”), Nasdaq BX, Inc. and The Nasdaq Stock Market LLC which all have business continuity and disaster recovery plans located within General 2, Section 12 of their respective rulebooks.[15]                                          The Exchange also proposes to reserve Sections 7-11 and 13-22 within General 2. Harmonizing the rule locations of the rules of the Nasdaq affiliated markets will make it easier for market participants to review and compare the rules of each Nasdaq market.                

#### Technical Amendments

                    The Exchange proposes to add new Options 4C and mark it as reserved. Phlx added a 4C to its Rulebook and this rule change will harmonize MRX's Rulebook structure to Phlx's Rulebook Structure.[16] 

#### 2. Statutory Basis

                    The Exchange believes that its proposal is consistent with Section 6(b) of the Act,[17]                                          in general, and furthers the objectives of Section 6(b)(5) of the Act,[18]                                          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.                

#### Options 2, Section 4(a)

                    The Exchange's proposal to remove certain rule text from Options 2, Section 4(a) that refrains Market Makers from purchasing a call option or a put option at a price more than $0.25 below parity is consistent with the Act. The Exchange desires to remove this restriction on Market Makers which does not exist on Cboe or other Nasdaq affiliated markets.[19]                                          The proposed rule text is currently waived on MRX pursuant to Options 2, Section 4(a)(2). The Exchange believes that this market maker provision is no longer necessary. Today, MRX incentivizes Market Makers through allocation [20]                                          to quote tightly in their assigned options series. Primary Market Makers and Competitive Market Makers also have other obligations with respect to market making [21]                                          in addition to other quoting obligations [22]                                          that they must abide by when quoting on MRX. Also, since the adoption of the rule, the Exchange has adopted the obvious error rule [23]                                          which permits the Exchange to review a transaction as potentially erroneous based on a theoretical price. Also, MRX orders are subject to trade-through compliance, thereby limiting the prices at which orders may execute.[24]                                          Market Makers are relied upon to provide liquidity on MRX, which benefits other Members who have the opportunity to interact with the order flow. The Exchange believes that the obligation to refrain from purchasing a call option or a put option at a price more than $0.25 below parity places yet another obligation on MRX Market Makers that is not required on Cboe or other Nasdaq markets. The Exchange believes that this additional obligation is not necessary to maintain fair and orderly markets and notes the Exchange has waived this obligation and the removal of this provision would remove an impediment to and perfect the mechanism of a free and open market and a national market system.

#### Bid/Ask Differentials

                    The Exchange's proposal to amend Options 2, Section 4(b)(4)(i) and Options 4A, Section 12(b)(i) to centralize the bid/ask differentials is consistent with the Act. Currently, MRX Options 4 and Options 4A rules are incorporated by reference to ISE. The Exchange recently filed a rule change [25]                                          to amend ISE Options 4 and Options 4A rules to relocate text concerning bid/ask differentials for long-term option series from ISE Options 4, Section 8(a) and ISE Options 4A, Section 12(b)(i). The ISE Rule Change added citations to Options 2, Section 4(b)(4)(i) to ISE Options 4, Section 8(a) and ISE Options 4A, Section 12(b)(i). MRX believes centralizing the bid/ask differentials within new Options 2, Section 4(b)(4)(i) will provide Primary Market Makers and Competitive Market Makers with centralized information regarding their bid/ask differential requirements.                

#### Business Continuity and Disaster Recovery Plan

                    The Exchange's proposal to relocate Supplementary Material .02 to Options 2, Section 4, concerning business continuity and disaster recovery plans, to General 2, Section 12, which is currently reserved, is consistent with the Act. This rule text will harmonize MRX's rules with that of Phlx, Nasdaq BX, Inc. and The Nasdaq Stock Market LLC which all have business continuity and disaster recovery plans located within General 2, Section 12 of their respective rulebooks.[26]                                          Harmonizing the rule locations of the rules of the Nasdaq affiliated markets will make it easier for market participants to review and compare the rules of each Nasdaq market. The Exchange also proposes to reserve Sections 7-10 and 13-22 within General 2. These changes are non-substantive as the rule text is not being amended.                

#### Technical Amendments

                    Adding Options 4C and reserving it is a non-substantive amendment which will harmonize MRX's Rulebook structure to Phlx's Rulebook Structure.[27] 

### 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.

#### Options 2, Section 4(a)

                    The Exchange's proposal to remove certain rule text from Options 2, Section 4(a) that refrains Market Makers from purchasing a call option or a put option at a price more than $0.25 below parity does not impose an undue burden on competition. The Exchange desires to remove this restriction on Market Makers which does not exist on Cboe or other Nasdaq affiliated markets.[28]                                          The proposed rule text is currently waived on MRX pursuant to Options 2, Section 4(a)(2). Market Makers are relied upon to provide liquidity on MRX, which benefits other Members who have the opportunity to interact with the order flow. The Exchange believes that the obligation to refrain from purchasing a call option or a put option at a price more than $0.25 below parity places yet another obligation on MRX Market Makers that is not required on Cboe or other Nasdaq markets. The Exchange believes that this additional obligation is not necessary to maintain fair and orderly markets and notes the Exchange has waived this obligation.                

#### Bid/Ask Differentials

The Exchange's proposal to amend Options 2, Section 4(b)(4) and Options 4A, Section 12(b)(i) to relocate text concerning bid/ask differentials for long-term option series does not impose an undue burden on competition. The Exchange's proposal will centralize the bid/ask differentials within new Options 2, Section 4(b)(4)(iii) and add a sentence to both Options 4, Section 8(a) and Options 4A, Section 12(b)(i) that cites to Options 2, Section 4(b)(4)(iii) for information on bid/ask differentials for the various products. The Exchange believes that this relocation will provide Primary Market Makers and Competitive Market Makers with centralized information regarding their bid/ask differential requirements.

#### Business Continuity and Disaster Recovery Plan

                    The Exchange's proposal to relocate Supplementary Material .02 to Options 2, Section 4, concerning business continuity and disaster recovery plans, to General 2, Section 12, which is currently reserved, does not impose an undue burden on competition. This rule text will harmonize MRX's rules with that of Phlx, Nasdaq BX, Inc. and The Nasdaq Stock Market LLC which all have business continuity and disaster recovery plans located within General 2, Section 12 of their respective rulebooks.[29]                                          Harmonizing the rule locations of the rules of the Nasdaq affiliated markets will make it easier for market participants to review and compare the rules of each Nasdaq market. This change is non-substantive as the rule text is not being amended.                

#### Technical Amendments

                    Adding Options 4C and reserving it is a non-substantive amendment which will harmonize MRX's Rulebook structure to Phlx's Rulebook Structure.[30]
