###### Securities and Exchange Commission

          - [Release No. 34-83797; File No. SR-MIAX-2018-22]

                    Pursuant to the provisions of 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 August 1, 2018, Miami International Securities Exchange LLC (“MIAX Options” or the “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 the Substance of the Proposed Rule Change

The Exchange is filing a proposal to amend the MIAX Options Fee Schedule (the “Fee Schedule”).

                    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 its Fee Schedule to (i) increase certain fees in certain Tiers for options transactions by MIAX Options Market Makers [3]                                          in standard option classes in the Penny Pilot Program [4]                                          (“Penny classes”) and in standard option classes which are not in the Penny Pilot Program (“non-Penny classes”) executed in the complex order [5]                                          book; (ii) increase the per contract surcharge assessed for transactions by all market participants, except for Priority Customers,[6]                                          which remove liquidity against a resting Priority Customer complex order on the strategy book for options in Penny classes and for options in non-Penny classes (“Complex Taker Surcharge”) and to broaden the application of the Complex Taker Surcharge to other types of transactions (described below) and consequently to rename it as the “Complex Surcharge;” (iii) increase the per contract credit assessable to Agency Orders (defined below) in a cPRIME Auction (“cPRIME Agency Order Credit”) by Members [7]                                          in Tier 4 of the Priority Customer Rebate Program (“PCRP”) [8]                                          and establish a limit as to                           ( print page 40374)                        how many contracts that the cPRIME Agency Order Credit shall apply; (iv) increase the per contract fee for Contra-side Orders (defined below) in non-Penny classes in a cPRIME Auction assessable to all market participants, except Priority Customers; (v) establish an enhanced cPRIME Break-up Credit (defined below) for options in Penny classes and non-Penny classes assessable to all market participants who experience a greater than sixty percent (60%) break-up of their order in a cPRIME Auction; and (vi) remove the discounted cPRIME Response Fee (defined below) for Members or its Affiliates that qualify for Priority Customer Rebate Program (defined below) volume tiers 3 or higher, for standard complex order options in Penny classes and non-Penny classes.                

#### Market Maker Complex Transaction Fees

                    Section 1(a)(i) of the Fee Schedule sets forth the Exchange's Market Maker Sliding Scale for Market Maker Transaction Fees (the “Sliding Scale”). The Sliding Scale assesses a per contract transaction fee on a Market Maker for the execution of simple orders and quotes (collectively, “simple orders”) and complex orders and quotes (collectively, “complex orders”). The percentage threshold by tier is based on the Market Maker's percentage of total national market maker volume in all options classes that trade on the Exchange during a particular calendar month, or total aggregated volume (“TAV”), and the Exchange aggregates the volume executed by Market Makers in both simple orders and complex orders for purposes of determining the applicable tier and corresponding per contract transaction fee amount.[9]                                          The Sliding Scale applies to all MIAX Options Market Makers for transactions in all products (except for mini-options, for which there are separate product fees), with fees for standard options in both Penny classes and non-Penny classes.                

                    Additionally, the Exchange assesses one per contract fee for complex orders in each tier for Penny classes, and one per contract fee for complex orders in non-Penny classes, with a surcharge for removing liquidity in a specific scenario, as described below. For simple orders, the Sliding Scale assesses a per contract transaction fee, which is based upon whether the Market Maker is a “Maker” or a “Taker.” [10]                                          Members that place resting liquidity,                     *i.e.,*                     quotes or orders on the MIAX Options System,[11]                                          are assessed the “maker” fee (each a “Maker”) and Members that execute against (remove) resting liquidity are assessed a higher “taker” fee (each a “Taker”). As an incentive for Market Makers to provide liquidity on the Exchange, the Exchange's Maker fees are lower than the Taker fees.                

                    Further, the Exchange provides certain discounted Market Maker transaction fees for Members and their qualified Affiliates [12]                                          that achieve certain volume thresholds through the submission of Priority Customer orders under the Exchange's PCRP, which is set forth on two tables: one setting forth the transaction fees applicable to Members and their Affiliates that are in PCRP Volume Tier 3 or higher; and the other setting forth the transaction fees applicable to Members and their Affiliates that are not in PCRP Volume Tier 3 or higher. The Sliding Scale also includes Maker and Taker fees in both tables in each Tier for simple orders in Penny classes and non-Penny classes where the fees are discounted/differentiated between the tables.                

The Exchange proposes to make the following changes for both Members and their Affiliates in PCRP Volume Tier 3 or higher and Members and their Affiliates not in PCRP Volume Tier 3 or higher: (i) Increase the fees in certain Sliding Scale Tiers for options transactions in Penny classes executed in the complex order book; and (ii) increase the fees in all Sliding Scale Tiers for options transactions in non-Penny classes executed in the complex order book. Specifically, the Exchange proposes to increase the fees for complex orders in options in Penny classes in Tier 2 from $0.19 to $0.24, in Tier 3 from $0.12 to $0.21, in Tier 4 from $0.07 to $0.20, and in Tier 5 from $0.05 to $0.19. The Exchange also proposes to increase the fees for complex orders in options in non-Penny classes in Tier 1 from $0.29 to $0.32, in Tier 2 from $0.23 to $0.29, in Tier 3 from $0.16 to $0.25, in Tier 4 from $0.11 to $0.24, and in Tier 5 from $0.09 to $0.23.

#### Complex Surcharge

                    The Exchange does not currently distinguish between a Maker and a Taker for complex order executions as it does in the traditional construct for simple orders and instead assesses the per contract transaction fee for all executions and a potential surcharge of $0.10 per executed contract for executions in complex orders. The current surcharge is assessed to a Market Maker and all other market participants except Priority Customers, when they remove liquidity by trading against a Priority Customer order that is resting on the Strategy Book.[13]                                          This surcharge is currently referred to as the                           ( print page 40375)                        “Complex Taker Surcharge”. This surcharge is similar in structure to Cboe Exchange, Inc. (“Cboe”) and NYSE American LLC (“NYSE American”) surcharges of the same type.[14] 

                    First, the Exchange proposes to increase the Complex Taker Surcharge on MIAX Market Makers in the Sliding Scale for both Members and their Affiliates in PCRP Volume Tier 3 or higher, and for Members and their Affiliates not in PCRP Volume Tier 3 or higher, in Section 1)a)i) of the Fee Schedule, from $0.10 to $0.12 in all Tiers. The Exchange also proposes to increase the Complex Taker Surcharge on other market participants (except for Priority Customers), including Public Customers [15]                                          that are not Priority Customers, non-MIAX Market Makers,[16]                                          non-Member Broker-Dealers,[17]                                          and Firms [18]                                          (collectively, the “Other Market Participants”) in Section 1)a)ii) of the Fee Schedule, from $0.10 to $0.12.                

Second, the Exchange proposes to broaden the application of the Complex Taker Surcharge so that it will now apply to a Market Maker and Other Market Participants (other than Priority Customers) when trading against a Priority Customer (i) on the Strategy Book; or (ii) as a Response or unrelated quote or order in a complex order auction other than a cPRIME Auction.

                    Exchange Rule 518(d) describes the process for determining if a complex order is eligible to begin a Complex Order Auction and to participate in a Complex Order Auction that is in progress, and provides that upon entry into the System or upon evaluation of a complex order resting at the top of the Strategy Book, complex auction-eligible orders may be subject to an automated request for responses (“RFR”).[19]                                          Members may submit Responses to the RFR, which can be either a complex Auction or Cancel (“AOC”) order or a complex AOC eQuote.                

                    Exchange Rule 518(b)(7) defines a cPRIME Order as a type of complex order that is submitted for participation in a cPRIME Auction and trading of cPRIME Orders is governed by Rule 515A, Interpretations and Policies .12.[20]                                          cPRIME Orders are processed and executed in the Exchange's PRIME mechanism, the same mechanism that the Exchange uses to process and execute simple PRIME orders, pursuant to Exchange Rule 515A.[21]                                          PRIME is a process by which a Member may electronically submit for execution an order it represents as agent (an “Agency Order”) against principal interest and/or solicited interest. The Member that submits the Agency Order (“Initiating Member”) agrees to guarantee the execution of the Agency Order by submitting a contra-side order representing principal interest or solicited interest (“Contra-Side Order”). When the Exchange receives a properly designated Agency Order for Auction processing, an RFR detailing the option, side, size and initiating price is broadcasted to MIAX Options participants up to an optional designated limit price. Members may submit responses to the RFR, which can be either an AOC order or an AOC eQuote. A cPRIME Auction is the price-improvement mechanism of the Exchange's System pursuant to which an Initiating Member electronically submits a complex Agency Order into a cPRIME Auction. The Initiating Member, in submitting an Agency Order, must be willing to either (i) cross the Agency Order at a single price against principal or solicited interest, or (ii) automatically match against principal or solicited interest, the price and size of a RFR that is broadcast to MIAX Options participants up to an optional designated limit price. Such responses are defined as cPRIME AOC Responses or cPRIME eQuotes.                

                    Specifically, the Exchange proposes to broaden the application of the Complex Taker Surcharge so that it will apply to an Electronic Exchange Member (“EEM”),[22]                                          for trading against a Priority Customer Complex Order for Penny and Non-Penny Classes, when trading against a Priority Customer: (i) On the Strategy Book; or (ii) as a Response or unrelated order in a complex order auction other than a cPRIME Auction. Consequently, the Exchange proposes to change the name of the surcharge from “Complex Taker Surcharge” to “Complex Surcharge” since the surcharge will apply to more complex transactions than just those transactions which remove liquidity from the Strategy Book. The Exchange notes that both Cboe and NYSE American apply their respective surcharges in a more expansive manner than the Exchange's current application of its surcharge, and similar to how the Exchange is proposing to expand its surcharge. However, Cboe caps its fees at $0.50 per contract in its complex order auction mechanisms. And NYSE American does not assess its surcharge in its paired complex auction mechanism. As proposed, the Exchange will apply its surcharge in its single-sided complex auction mechanism (COA), but it will not apply the surcharge in its paired complex auction mechanism (cPRIME). Accordingly, as proposed to be expanded, the Exchange's surcharge will be more in line with Cboe's and NYSE American's surcharges, but it will be no more expansive than either such exchange.[23] 

                    Additionally, the Exchange proposes to remove the Discounted cPRIME Response Fee of $0.46 per contract for Members or its Affiliates that qualify for Priority Customer Rebate Program volume tiers 3 or higher and submit a cPRIME AOC Response that is received during the Response Time Interval and executed against the cPRIME Order, or a cPRIME Participating Quote or Order that is received during the Response Time Interval and executed against the cPRIME Order for standard complex order options in Penny classes; and                           ( print page 40376)                        remove the Discounted cPRIME Response Fee of $0.95 per contract in the same tiers, for standard complex order options in non-Penny classes. By removing these discounts, the Exchange will charge such Members and their Affiliates the standard cPRIME rates in the cPRIME tier that otherwise apply to such transactions. The Exchange notes that this is a business decision to discontinue offering the discount, and as a result, it will align its fees more closely to those of NYSE American.[24] 

#### cPRIME Agency Order Fees

In the PCRP, the Exchange assesses an Agency Order Credit for cPRIME Agency Orders. The Exchange currently credits each Member $0.10 per contract per leg for each Priority Customer complex order submitted into the cPRIME Auction as a cPRIME Agency Order in each Tier. However, no credit is paid if the cPRIME Agency Order executes against a Contra-Side Order which is also a Priority Customer. The Exchange proposes to increase the Agency Order Credit for cPRIME Agency Orders submitted by Members who are in PCRP Volume Tier 4 from $0.10 to $0.22. The purpose of such increase in Tier 4 is to encourage market participants to submit more Priority Customer cPRIME Agency Orders and therefore increase Priority Customer order flow. The Exchange additionally proposes to limit the cPRIME Agency Order Credit to be payable to the first 1,000 contracts per leg for each cPRIME Agency Order. Such limit will be applicable to all Tiers of the PCRP.

#### cPRIME Contra-Side Order Fees

                    The Exchange assesses a per contract fee to all market participants except Priority Customers for Contra-Side Orders in cPRIME Auctions. Currently, the cPRIME Contra-Side Order Fee is $0.05 for options in Penny classes and non-Penny classes. The Exchange proposes to increase the fee assessed to all market participants except Priority Customers for cPRIME Contra-Side Orders for options in non-Penny classes from $0.05 to $0.07. To implement this change on the Fee Schedule, the Exchange is proposing to bifurcate the fee for Penny classes and non-Penny classes by adding a new column to the table under Section 1)a)vi) of the Fee Schedule for the cPRIME Contra-Side Order fees assessable for orders in non-Penny classes setting forth the increased fee of $0.07 for all market participants except Priority Customers. The purpose of increasing such fee for options in non-Penny classes is to more closely align the Exchange's fees for cPRIME Contra-Side Orders with similar fees of other exchanges.[25] 

#### cPRIME Break-Up Credit

The Exchange applies a break-up credit to an EEM that submitted a cPRIME Order for agency contracts that are submitted to the cPRIME Auction that trade with a cPRIME AOC Response or a cPRIME Participating Quote or Order that trades with the cPRIME Order (“cPRIME Break-up Credit”). Currently, the per contract cPRIME Break-up Credit payable to all market participants for options in Penny classes is $0.25 and for options in non-Penny classes is $0.60. The current cPRIME Break-up Credit does not take into account the degree to which the cPRIME Order was broken up.

                    The Exchange now proposes to take into account the degree to which the cPRIME Order was broken up, through paying a higher credit amount if the cPRIME Order experienced a greater degree of break-up. In particular, the Exchange proposes to pay an enhanced cPRIME Break-up Credit to all market participants who experience a greater than sixty percent (60%) break-up of their cPRIME Order in a cPRIME Auction, instead of the regular cPRIME Break-up Credit specified in the Fee Schedule. If the market participant experiences a greater than sixty percent (60%) break-up of their cPRIME Order in a cPRIME Auction, then it shall be credited $0.28, an additional $0.03 per contract, for options in Penny classes, and $0.72, an additional $0.12 per contract, for options in non-Penny classes. For example, if the original cPRIME Agency Order in a Penny class was for 100 contracts and the Member received only 30 contracts of the original cPRIME Order as a result of the break-up, and the other 70 contracts traded with a cPRIME AOC response or a cPRIME Participating Quote or Order (which equals 70%), then they would be credited $0.28 as a cPRIME Break-up Credit. As another example, if the original cPRIME Agency Order in a Penny class was for 100 contracts and the Member received 40 contracts of the original cPRIME Order as a result of the break-up and the other 60 contracts traded with a cPRIME AOC response or a cPRIME Participating Quote or Order (which equals 60%), then they would only be credited $0.25 as a cPRIME Break-up Credit. The decision to offer an enhanced cPRIME Break-up Credit is based on an analysis of current revenue and volume levels and is intended to encourage market participants to continue participating in cPRIME Auctions. The Exchange believes that by offering Members this enhanced cPRIME Break-up Credit, it will be able to further incentivize Members to send cPRIME orders to the Exchange, and enable it to better compete with NYSE American. Although it is a business decision to bifurcate the Exchange's enhanced cPRIME Break-up Credit based on the degree to which the cPRIME Order is broken up, the Exchange notes that its credit still remains lower than those of NYSE American, which the Exchange believes will serve to enhance competition. There are several approaches used by Exchanges to attract certain types of order flow, and many approaches often rely on the existence of certain conditions and thresholds being met.[26]                                          This proposed approach of offering an enhanced credit based on the degree of break-up of a cPRIME Order is another variation of one such type of condition.                

The proposed rule changes are scheduled to become operative August 1, 2018.

#### 2. Statutory Basis

                    The Exchange believes that its proposal to amend its fee schedule is consistent with Section 6(b) of the Act [27]                                          in general, and furthers the objectives of Section 6(b)(4) of the Act,[28]                                          in that it is an equitable allocation of reasonable fees and other charges among Exchange members and issuers and other persons using its facilities, and 6(b)(5) of the Act,[29]                                          in that 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,                           ( print page 40377)                        to remove impediments to and perfect the mechanisms of a free and open market and a national market system and, in general, to protect investors and the public interest.                

                    The proposed fee increases for the various Sliding Scale tiers in Penny and non-Penny classes for complex orders is equitable and not unfairly discriminatory because all MIAX Options Market Makers are subject to the same fees and access to the Exchange is offered on terms that are not unfairly discriminatory. The Exchange initially set its complex order fees at the various volume levels based upon business determinations and an analysis of current complex order fees and volume levels at other exchanges. When the Exchange initially adopted complex order fees, it set its complex order fees lower than other exchanges in order to encourage its Market Makers to reach for higher volume levels in order to achieve greater discounts. For competitive and business reasons, the Exchange believes that it is now appropriate to increase complex order fees to be more in line with competing exchanges. The Exchange notes that the increased complex order fees are comparable to those assessed by other exchanges.[30] 

Furthermore, the proposed increases to the fees for complex orders in Penny and non-Penny classes in the specified tiers promotes just and equitable principles of trade, fosters cooperation and coordination with persons engaged in facilitating transactions in securities, and protects investors and the public interest, because even with the increases, the Exchange's proposed fees for Market Makers complex orders still remain competitive with certain other options exchanges offering comparable pricing models, and should enable the Exchange to continue to attract order flow and grow market share. The Exchange believes that the amount of such fees, as proposed to be increased, will continue to encourage MIAX Options Market Makers to send complex orders to the Exchange. To the extent that order flow is increased by the proposal, market participants will increasingly compete for the opportunity to trade on the Exchange, including sending more orders which will have the potential to be assessed lower fees and higher rebates than certain other competing options exchanges. The resulting increased volume and liquidity will benefit all Exchange participants by providing more trading opportunities and tighter spreads.

                    The Exchange's proposal to increase the Complex Taker Surcharge and broaden its application and rename it as the “Complex Surcharge” is consistent with Section 6(b)(4) of the Act [31]                                          because it applies equally to all market participants (both MIAX Market Makers and Other Market Participants, except Priority Customers) that would be charged such Complex Surcharge. Assessing the Complex Surcharge to MIAX Market Makers and Other Market Participants (except Priority Customers), in a broader application, similar to that of other exchanges, is reasonable and not unfairly discriminatory because it will provide MIAX Options Market Makers and Other Market Participants with equal surcharges when trading against a Priority Customer. As stated above, the Complex Surcharge is similar to surcharges assessed on Cboe and NYSE American.[32]                                          The Exchange notes that, although the increase of the Complex Surcharge represents a slight fee increase, the Exchange believes that this increase is fair and equitable because it is in line with the amount of surcharges assessed on other options exchanges, when trading against Priority Customer Complex Orders, including trading in a complex order book, complex order auctions, and complex order price improvement mechanisms.[33] 

                    The Exchange's proposal to broaden the application of the Complex Taker Surcharge and to rename it as the “Complex Surcharge” is also consistent with Section 6(b)(5) of the Act [34]                                          because it perfects the mechanisms of a free and open market and a national market system and protect investors and the public interest by aligning the broader application of the Complex Surcharge and the definition of Complex Surcharge to that of other options exchanges,[35]                                          which will help to create consistency and uniformity in the marketplace. The proposed Complex Surcharge increase is similar to the surcharge increase effected by Cboe and NYSE American.[36]                                          The Exchange believes for these reasons that the Complex Surcharge and the broadened application of it, is equitable, reasonable and not unfairly discriminatory, and thus consistent with the Act.                

                    The Exchange's proposal to remove the Discounted cPRIME Response Fee of $0.46 per contract for Members or its Affiliates that qualify for Priority Customer Rebate Program volume tiers 3 or higher and submit a cPRIME AOC Response that is received during the Response Time Interval and executed against the cPRIME Order, or a cPRIME Participating Quote or Order that is received during the Response Time Interval and executed against the cPRIME Order for standard complex order options in Penny classes; and remove the Discounted cPRIME Response Fee of $0.95 per contract in the same tiers, for standard complex order options in non-Penny classes, is consistent with Section 6(b)(4) of the Act [37]                                          because it applies equally to all market participants and although by removing this discount, the Exchange notes this would increase the cPRIME Response Fee for some market participants, it represents a slight increase, and the Exchange believes that this increase is fair and equitable because it is in line with the amount of surcharges assessed on other options exchanges.[38]                                          Further, the proposal is also consistent with Section 6(b)(5) of the Act [39]                                          because it perfects the mechanisms of a free and open market and a national market system and protects investors and the public interest because it will align the Exchange's rule to that of other options exchanges, which will help to create consistency and uniformity in the marketplace. In addition, the removal of the discounted for the cPRIME Response Fee would align the Exchange's fees closer to those of another options exchange.[40] 

                    The Exchange's proposal to increase the cPRIME Agency Order Credit assessable to cPRIME Agency Orders by Members in Tier 4 of the PCRP is consistent with Section 6(b)(4) of the Act [41]                                          because it applies equally to all participants in that tier. The Exchange believes that the proposed PCRP rebate increase in Tier 4 for Priority Customer orders submitted into cPRIME Auctions is fair, equitable, and not unreasonably discriminatory. The PCRP is reasonably designed because it will incentivize providers of Priority Customer order flow to send that Priority Customer order flow to the Exchange in order to obtain the highest volume threshold and receive a credit in a manner that enables the Exchange to improve its overall competitiveness and strengthen its                           ( print page 40378)                        market quality for all market participants.                

                    In addition, the proposal is also consistent with Section 6(b)(5) of the Act [42]                                          because it perfects the mechanisms of a free and open market and a national market system and protects investors and the public interest because, while only Priority Customer order flow qualifies for the rebate program under the PCRP and specifically only order flow by Members in Tier 4 of the PCRP will receive the greater rebate, an increase in Priority Customer order flow will bring greater volume and liquidity, which benefit all market participants by providing more trading opportunities and tighter spreads. To the extent Priority Customer order flow is increased by the proposal, market participants will increasingly compete for the opportunity to trade on the Exchange including sending more orders and providing narrower and larger-sized quotations in the effort to trade with such Priority Customer order flow.                

                    The Exchange's proposal to establish a limit as to how many contracts the cPRIME Agency Order Credit shall apply to is consistent with Section 6(b)(4) of the Act [43]                                          because it applies equally to all market participants who submit cPRIME Agency Orders. Further, the proposal is also consistent with Section 6(b)(5) of the Act [44]                                          because it perfects the mechanisms of a free and open market and a national market system and protects investors and the public interest because it will align the Exchange's rule to that of other options exchanges, which will help to create consistency and uniformity in the marketplace. It is also not novel since other exchanges similarly limit a similar rebate to the first 1,000 contracts.[45] 

                    The Exchange's proposal to increase the cPRIME Contra-Side Orders fees assessable to all market participants except for Priority Customers in non-Penny classes is consistent with Section 6(b)(4) of the Act [46]                                          because the Exchange believes that it is reasonable to assess lower transaction and credit rates to options in Penny classes than non-Penny classes. The Exchange believes that options which trade at these wider spreads merit offering greater inducement for market participants.                

The Exchange believes that is equitable and not unfairly discriminatory that Priority Customers be charged lower fees in cPRIME Auctions than other market participants. The exchanges, in general, have historically aimed to improve markets for investors and develop various features within their market structure for customer benefit. The Exchange assesses Priority Customers lower or no transactions fees because Priority Customer order flow enhances liquidity on the Exchange for the benefit of all market participants. Priority Customer liquidity benefits all market participants by providing more trading opportunities, which attracts Market Makers. An increase in the activity of these market participants in turn facilitates tighter spreads, which may cause an additional corresponding increase in order flow from other market participants.

Moreover, the Exchange believes that assessing all other market participants that are not Priority Customers a higher transaction fee than Priority Customers for cPRIME Order transactions is reasonable, equitable, and not unfairly discriminatory because these types of market participants are more sophisticated and have higher levels of order flow activity and system usage. This level of trading activity draws on a greater amount of system resources than that of Priority Customers, and thus, generates greater ongoing operational costs. Further, the Exchange believes that charging all market participants that are not Priority Customers the same fee for all cPRIME transactions is not unfairly discriminatory as the fees will apply to all these market participants equally.

                    In addition, the proposal is also consistent with Section 6(b)(5) of the Act [47]                                          because it perfects the mechanisms of a free and open market and a national market system and protects investors and the public interest because, within the cPRIME Auction, the fee difference between Penny and non-Penny classes provides greater opportunity for market participants to offer price improvement. As such, the Exchange believes that the opportunity for additional price improvement provided by these wider spreads again merits offering greater incentive for market participants to increase the potential price improvement for customer orders in these transactions.                

                    The Exchange's proposal to pay an enhanced cPRIME Break-up Credit for options in Penny classes and non-Penny classes to all market participants who experience a greater than sixty percent (60%) break-up of their cPRIME Order in a cPRIME Auction is consistent with Section 6(b)(4) of the Act [48]                                          because it will encourage market participants to continue participating in cPRIME Auctions. The Exchange believes that the enhanced cPRIME Break-up Credit should improve market quality for all market participants. Additionally, the Exchange believes that by offering this enhanced cPRIME Break-up Credit, it will be able to incentivize initiating orders in order to compete with NYSE American. Although it is a business decision to bifurcate the Exchange's enhanced cPRIME Break-up Credit, the Exchange notes that its credit still remains lower than those of NYSE American, which the Exchange believes will serve to enhance competition.[49] 

                    In addition, the proposal is also consistent with Section 6(b)(5) of the Act [50]                                          because it perfects the mechanisms of a free and open market and a national market system and protects investors and the public interest because it applies equally to all cPRIME orders which are subject to a break-up and access to the Exchange is offered on terms that are not unfairly discriminatory.                

### 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. The Exchange believes that the proposed increase in the Complex Surcharge for complex transactions is intended to promote narrower spreads and greater liquidity at the best prices. The fee-based incentives for market participants to provide liquidity by submitting complex orders to the Exchange, and thereby improve liquidity on the Exchange, should enable the Exchange to attract order flow and compete with other exchanges which also provide such incentives to their market participants for similar transactions.

                    The Exchange believes that increased complex order flow will bring greater volume and liquidity which in turn benefits all market participants by providing more trading opportunities and tighter spreads. Therefore, any potential effects that the increased Complex Surcharge for complex transactions may have on intra-market competition are justifiable due to the reasons stated above.                          ( print page 40379)    

The Exchange believes that the proposed changes to the rebates and fees for participation in a cPRIME Auction are not going to have an impact on intra-market competition based on the total cost for participants to transact in such order types versus the cost for participants to transact in the other order types available for trading on the Exchange. As noted above, the Exchange believes that the proposed changes in the rebates and fees for the cPRIME Auction are comparable to that of other exchanges offering similar electronic price improvement mechanisms for complex orders and the Exchange believes that, based on experience with electronic price improvement crossing mechanisms on other markets, market participants understand that the price-improving benefits offered by the cPRIME Auction justify the transaction costs associated with the cPRIME Auction. To the extent that there is a difference between non-cPRIME Auction transactions and cPRIME Auction transactions, the Exchange does not believe this difference will cause participants to refrain from responding to cPRIME Auctions.

                    With respect to cPRIME Auctions, the Exchange notes that Cboe caps its fees at $0.50 per contract in its complex order auction mechanisms. And NYSE American does not assess its surcharge in its paired complex auction mechanism. As proposed, the Exchange will apply its surcharge in its single-sided complex auction mechanism (COA), but it will not apply the surcharge in its paired complex auction mechanism (cPRIME). Accordingly, as proposed to be expanded, the Exchange's surcharge will be more in line with Cboe's and NYSE American's surcharges, but it will be no more expansive than either such exchange.[51]                                          Because the Complex Surcharge will not be applied in its cPRIME Auction, the Exchange believes that the proposed rule change will not impose any burden on competition not necessary or appropriate in furtherance of the purposes of the Act.                

The Exchange notes that it operates in a highly competitive market in which market participants can readily favor competing venues if they deem fee levels at a particular venue to be excessive. In such an environment, the Exchange must continually adjust its fees to remain competitive with other exchanges and to attract order flow. The Exchange believes that the proposed rule change reflects this competitive environment because they modify the Exchange's fees in a manner that encourages market participants to provide liquidity and to send order flow to the Exchange.

5.                             A “complex order” is any order involving the concurrent purchase and/or sale of two or more different options in the same underlying security (the “legs” or “components” of the complex order), for the same account, in a ratio that is equal to or greater than one-to-three (.333) and less than or equal to three-to-one (3.00) and for the purposes of executing a particular investment strategy. A complex order can also be a “stock-option” order, which is an order to buy or sell a stated number of units of an underlying security coupled with the purchase or sale of options contract(s) on the opposite side of the market, subject to certain contingencies set forth in the proposed rules governing complex orders.

An “Appointed Market Maker” is a MIAX Market Maker (who does not otherwise have a corporate affiliation based upon common ownership with an EEM) that has been appointed by an EEM and an “Appointed EEM” is an EEM (who does not otherwise have a corporate affiliation based upon common ownership with a MIAX Market Maker) that has been appointed by a MIAX Market Maker, pursuant to the following process. A MIAX Market Maker appoints an EEM and an EEM appoints a MIAX Market Maker, for the purposes of the Fee Schedule, by each completing and sending an executed Volume Aggregation Request Form by email to                         *membership@miaxoptions.com*                         no later than 2 business days prior to the first business day of the month in which the designation is to become effective. Transmittal of a validly completed and executed form to the Exchange along with the Exchange's acknowledgement of the effective designation to each of the Market Maker and EEM will be viewed as acceptance of the appointment. The Exchange will only recognize one designation per Member. A Member may make a designation not more than once every 12 months (from the date of its most recent designation), which designation shall remain in effect unless or until the Exchange receives written notice submitted 2 business days prior to the first business day of the month from either Member indicating that the appointment has been terminated.
