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 October 22, 2021, Miami International Securities Exchange LLC (“MIAX” or “Exchange”) filed with the Securities and Exchange Commission (“Commission”) a 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 is filing a proposal to amend the MIAX Options Fee Schedule (the “Fee Schedule”) to make non-substantive, clarifying changes.

The text of the proposed rule change is available on the Exchange's website at http://www.miaxoptions.com/​rule-filings,, at MIAX's principal office, 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 the Fee Schedule to make non-substantive, clarifying changes to Sections 3)b) and 5)d)ii) for the monthly Trading Permit fees for Market Makers ^[3] and the monthly MIAX Express Interface (“MEI”) ^[4] Port fees for Market Makers. The Exchange does not propose to amend the amount of Trading Permit fees or MEI Port fees in this filing. The Exchange also does not propose to amend the calculation methodology for Trading Permit fees or MEI Port fees in this filing.

Monthly Market Maker Trading Permit Fee Clarifying Changes

First, the Exchange proposes to amend Section 3)b) of the Fee Schedule to amend the text below the table for the monthly Trading Permit fees applicable to Market Makers. Specifically, the Exchange proposes to add the following two clarifying sentences to begin the explanatory paragraph following the table for the monthly Trading Permit fees applicable to Market Makers:

For the calculation of the monthly Market Maker Trading Permits, the applicable fee rate is the lesser of either the per class basis or percentage of total national average daily volume measurement. The amount of monthly Market Maker Trading Permit Fee will be based upon the number of classes in which the Market Maker was assigned to quote on any given day within the calendar month, or upon the class volume percentages set forth in the above table.

The Exchange also proposes to remove the following sentence to the end of the explanatory paragraph, which is currently the first sentence of the explanatory paragraph below the table for the monthly Trading Permit fees applicable to Market Makers:

For the calculation of the monthly Market Maker Trading Permit Fees, the number of classes is defined as the greatest number of classes the Market Maker was assigned to quote in on any given day within the calendar month and the class volume percentage is based on the total national average daily volume in classes listed on MIAX in the prior calendar quarter.

In place of the deleted sentence described above, the Exchange proposes to insert the following two sentences, which will become sentences three and four of the revised explanatory paragraph:

The Exchange will assess MIAX Market Makers the monthly Market Maker Trading Permit Fee based on the greatest number of classes listed on MIAX that the MIAX Market Maker was assigned to quote in on any given day within a calendar month. The class volume percentage is based on the total national average daily volume in classes listed on MIAX in the prior calendar quarter.

The Exchange notes that these two sentences are a combination of sentences already included in the explanatory paragraph. In connection with all of the changes described above, the Exchange proposes to delete the following sentence:

The Exchange will assess MIAX Market Makers the monthly Market Maker Trading Permit Fee based on the greatest number of classes listed on MIAX that the MIAX Market Maker was assigned to quote in on any given day within a calendar month and the applicable fee rate that is the lesser of either the per class basis or percentage of total national average daily volume measurement.

The Exchange notes that all of these changes, when taken together, do not alter the calculation methodology for how the Exchange currently calculates monthly Trading Permit fees for Market Makers. These changes are being made solely to clarify the explanatory paragraph below the table of fees for monthly Trading Permit fees for Market Makers. The Exchange believes that these revised sentences summarize that the monthly Market Maker Trading Permit fee rate is the lesser of the per class basis or the percentage of total national average daily volume measure and better clarifies how the MIAX Market Maker Trading Permit fee will continue to be calculated and applied each month. The Exchange does not propose to amend the amount or calculation of the monthly Trading Permit fee for Market Makers.

MEI Port Fee Clarifying Changes

Next, the Exchange proposes to amend Section 5)d)ii) of the Fee Schedule to make non-substantive, clarifying changes to the explanatory paragraph below the table of MEI Port fees applicable to Market Makers. The Exchange proposes to move the current first sentence of the explanatory paragraph below the table of MEI Port fees applicable to Market Makers in Section 5)d)ii) to now be the final sentence. In its place, the Exchange proposes to add the following sentence: “The applicable fee rate is the lesser of either the per class basis or percentage of total national average daily volume measurement.” In connection with this change, the Exchange proposes to amend the sentence that will now follow the new first sentence of the explanatory paragraph. In particular, the Exchange proposes to move footnote 26 to the second sentence of the explanatory paragraph to contain the defined term in footnote 26 for “MIAX Express Interface (`MEI')” Port.^[5] The final sentence of the explanatory paragraph will now read as follows: “MIAX will assess monthly MEI Port Fees on Market Makers in each month the Member has been credentialed to use the MEI Port in the production environment and has been assigned to quote in at least one class.”

Further, the Exchange proposes to amend the second sentence of the explanatory paragraph to remove the word “and” that connects the two clauses describing how the Exchange calculates the monthly MEI Port fee for Market Makers. In place of the word “and,” the Exchange proposes to clarify that the amount of the monthly MEI Port fee will be based upon the number of classes in which the Market Maker was assigned to quote on any given day within the calendar month, or upon the class volume percentages set forth in the MEI Port fee table.

The Exchange further proposes to remove the fifth sentence of the explanatory paragraph below the table of MEI Port fees in Section 5)d)ii) and move it up in the paragraph, immediately following the second sentence. With this change, the third sentence of the explanatory paragraph will be as follows: “The Exchange will assess MIAX Market Makers the monthly MEI Port Fee based on the greatest number of classes listed on MIAX that the MIAX Market Maker was assigned to quote in on any given day within a calendar month.” This phrase is currently contained in the fifth sentence of the explanatory paragraph and the Exchange now proposes to make the phrase its own sentence and move it earlier in the paragraph. The Exchange believes that these revised sentences summarize that the monthly MEI Port fee rate is the lesser of either the per class basis or percentage of total national average daily volume measurement and better clarifies how the monthly MEI Port fee for Market Makers will continue to be calculated and applied. The Exchange does not propose to amend the amount or calculation of the monthly MEI Port fee for Market Makers.

2. Statutory Basis

The Exchange believes that its proposal to amend its Fee Schedule is consistent with Section 6(b) of the Act ^[6] in general, and furthers the objectives of Section 6(b)(4) of the Act ^[7] in particular, in that it is an equitable allocation of reasonable fees and other charges among its members and issuers and other persons using its facilities. The Exchange also believes the proposal furthers the objectives of Section 6(b)(5) of the Act 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 and is not designed to permit unfair discrimination between customers, issuers, brokers, and dealers.

The Exchange believes the proposed changes are consistent with Section 6(b)(4) of the Act in that they are reasonable, equitable, and not unfairly discriminatory because they are non-substantive, clarifying changes regarding the Exchange's monthly Trading Permit and MEI Port fees applicable to Market Makers and will reduce the risk of confusion to market participants. The proposed changes promote just and equitable principles of trade, 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 clarifying how the MIAX Market Maker Trading Permit fee and the MEI Port fee will be calculated and applied each month. The Exchange believes that these proposed changes will provide greater clarity to Members and the public regarding the Exchange's Fee Schedule and that it is in the public interest for the Fee Schedule to be accurate and concise so as to eliminate the potential for confusion.

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. Specifically, the Exchange believes the proposed change will not impose any burden on intra-market competition as the proposed rule change will have no impact on competition as it is not designed to address any competitive issue but rather is designed to remedy minor non-substantive, clarifying issues and provide added clarity to the Fee Schedule. In addition, the Exchange does not believe the proposal will impose any burden on inter-market competition as the proposal does not address any competitive issues and is intended to protect investors by providing further transparency regarding the Exchange's Fee Schedule.

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

Written comments were neither solicited nor received.

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

The foregoing rule change has become effective pursuant to Section 19(b)(3)(A)(ii) of the Act,^[8] and Rule 19b-4(f)(2) ^[9] 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 shall institute proceedings to determine whether the proposed rule should be approved or disapproved.
