## 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 purpose of this rule change is to permit Market Makers to enter principal orders to buy or sell options in the options classes to which they are appointed under Rule 802 [4]                                          for all order types listed in Rule 715 except for Stopped Orders,[5]                                          Reserve Orders [6]                                          and Customer Cross Orders.[7]                                          This filing is intended to permit Market Makers to execute most of the same order types, which today they are permitted to enter on other options markets.[8]                                          In addition, this filing is intended to amend MRX Rule 805(b)(1) to indicate that Reserve Orders are not permitted to be entered by MRX Market Makers in non-                          ( print page 3197)                        appointed options classes. Today, MRX Market Makers may not enter Reserve Orders in either appointed or non-appointed options classes. Today, while the System prohibits MRX Market Makers from entering Reserve Orders, MRX Rule 805(b)(1) does not indicate the restriction.                

#### Appointed Options Classes

                    Today, as noted in MRX Rule 805(a), a Market Maker may not place principal orders to buy or sell options in the options classes to which they are appointed under Rule 802, other than opening only orders,[9]                                          immediate-or-cancel orders,[10]                                          market orders, fill-or-kill orders,[11]                                          sweep orders,[12]                                          and block-size orders [13]                                          executed through the Block Order Mechanism [14]                                          pursuant to Rule 716(c). At this time, the Exchange proposes to expand the order types which Market Makers are permitted to enter on MRX.[15]                                          The Exchange is amending MRX Rule 805(a) to make clear which order types a Market Maker in an appointed options class may submit. Additionally, ISO Orders, All-Or-None Orders, Stop Orders, Qualified Contingent Cross Orders, Attributable Orders, Do-Not-Route Orders, Opening Sweep Orders, Cancel and Replace Orders,[16]                                          and Add Liquidity Orders are accepted on MRX today from Market Makers as principal orders as modifiers of the allowable non-resting order types, although they are not specifically detailed in the rule. This rule change will further detail and align the rule text with the system functionality by making clear that Maker Makers may enter all order types defined in Rule 715 in the options classes to which they are appointed under Rule 802, except Stopped Orders, Reserve Orders and Customer Cross Orders.                

                    Today, MRX Market Makers, who are appointed and non-appointed in a particular options class, may submit orders without limitation, unless otherwise restricted by the order type as discussed herein. The Exchange proposes to permit Market Makers to enter all order types, which are listed in MRX Rule 715, except for Stopped Orders, Reserve Orders and Customer Cross Orders. The Exchange notes that today Market Makers are not eligible to execute either Customer Cross Orders, which are Customer orders, or Stopped Orders, which are intended for the account of a customer.[17]                                          With respect to Reserve Orders, the Exchange proposes to continue to restrict Market Makers from entering Reserve Orders in their appointed options class. The Exchange believes that Market Maker liquidity should be displayed liquidity. For these reasons, and to remain competitive with other markets, the Exchange proposes to permit Market Makers to enter all orders they are eligible to submit in their appointed class with the exception of Reserve Orders and also restrict Reserve Orders in the non-appointed classes.                

#### Non-Appointed Options Classes

Today, for the reasons noted above, the Exchange does not permit Market Makers to enter Reserve Orders in non-appointed options classes. However, the current rule text does not provide this limitation. The Exchange proposes to amend the current rule text at MRX Rule 805(b)(1) to codify this limitation.

#### 2. Statutory Basis

                    The Exchange believes that its proposal is consistent with Section 6(b) of the Act,[18]                                          in general, and furthers the objectives of Section 6(b)(5) of the Act,[19]                                          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, by providing Market Makers access to trade order types which are currently permissible to be traded in on other options exchanges today.[20]                                          The Exchange believes that permitting Market Makers to enter all eligible order types, except Reserve Orders, in both appointed and non-appointed options classes offers no advantage to Market Makers under the Exchange's market structure, including, but not limited to, under the priority and trade allocation rules in MRX Rule 713 and various risk protection mechanism rules applicable to Market Makers in MRX Rule 804.[21]                                          Today, other non-Market Maker participants may submit these order types on MRX.                

                    The Exchange notes that previously, Nasdaq ISE, LLC prohibited non-customer trading by Electronic Access Members (“EAMs”) for principal or agent transactions.[22]                                          At that time, ISE represented that, in an electronic market, non-customer market orders have the potential to create market volatility by trading at different price levels until their order is fully executed. ISE further noted that, without this restriction, non-customers would be able to use large-size orders to quickly take out ISE's entire order book without giving other market participants an                           ( print page 3198)                        opportunity to react.[23]                                          Today, EAMs on ISE may submit non-customer limit orders regardless of the size of the order where previously EAMs were prohibited from submitting orders for non-customers that caused ISE's best bid and offer to be for less than 10 contracts.[24] 

                    The Exchange notes that these restrictions never existed on MRX. MRX believes that these restrictions should not exist today because there is no reason to restrict Market Makers in entering order types, except for the restriction related to Reserve Orders, in options classes in which they are appointed. Unlike other order types, the Reserve Order is a limit order that contains both a displayed portion and a non-displayed portion.[25]                                          Both the displayed and non-displayed portions of a Reserve Order are available for potential execution against incoming marketable orders. When the displayed portion of a Reserve Order is decremented, either in full or in part, it shall be refreshed from the non-displayed portion of the resting Reserve Order. The Exchange believes that because a Reserve Order contains a non-displayed portion, Market Makers should not be permitted to enter this order. Market Makers are required to make markets that, absent changed market conditions, will be honored for the number of contracts entered into the Exchange's System in all series of options classes to which the market maker is appointed.[26]                                          The Exchange believes that these markets should be transparent. Today, MRX Market Makers are not permitted to enter Reserve Orders in either appointed or non-appointed options classes. The Exchange proposes to specifically note this limitation in both Rule 805(a) and (b) as an exception. The Exchange notes that this limitation is specifically not noted in Rule 805(b) today despite the fact that the limitation exists in the System today.                

The Exchange is also amending MRX Rule 805(a) to detail the types of non-resting order types and their modifiers with respect to ISO Orders, All-Or-None Orders, Stop Orders, Qualified Contingent Cross Orders, Attributable Orders, Do-Not-Route Orders, Opening Sweep Orders, Cancel and Replace Orders, and Add Liquidity Orders. This rule change will detail and align the rule text with the system functionality and make clear which order types a Market Maker may submit in appointed options classes.

                    MRX Market Makers continue to be obligated to add liquidity on MRX. The Exchange also notes that MRX Rule 805(b)(2) and (3) restricts the number of contracts that a Market Maker may enter in an options class to which the Market Maker is not appointed.[27]                                          The Exchange notes that it also requires Market Makers to abide by certain quoting requirements, in the options classes in which they are appointed pursuant to MRX Rule 802, in order to maintain the status of a Market Maker.[28]                                          The Exchange believes that permitting a Market Maker to enter additional order types, except Reserve Orders, in their appointed options class will permit Market Makers additional latitude to conduct business on MRX and effectively compete with other market makers on other options exchanges. Quotes and orders entered by a Market Maker may not interact against quotes and orders entered on the opposite side of the market by the same Market Maker.[29] 

### 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. Today, NYSE Arca and NYSE American place no limitation on the types of orders that can be entered by market makers in their appointed class.[30]                                          Accordingly, the Exchange believes that this proposal does not impose an undue burden on inter-market competition because each options exchange generally determines permissible order types for market makers in its trading environment based on the exchange's individual business policy, objectives, and trading system. The Exchange's proposal reflects its policy and objectives, and does not impose an undue burden on intra-market competition because it treats all market makers uniformly with respect to permissible order types. Further, this rule change will align the system functionality with the rule text to reflect the types of orders a Market Maker in both appointed and non-appointed options class may submit. The current rule text is not accurate. This rule filing is intended to detail and align the rule text with the system functionality in the current text of Rule 805(a) and (b). This proposal will make clear which order types a Market Maker may submit in both appointed and non-appointed options classes.                

                    Further, Market Makers, unlike other market participants, are required to abide by certain quoting requirements, in the options classes in which they are appointed pursuant to MRX Rule 802, in order to maintain the status of a Market Maker.[31]                                          The Exchange also notes that MRX Rule 805(b)(2) and (3) restricts the number of orders that a Market Maker may enter in an options class to which the Market Maker is not appointed.[32]                                          The Exchange believes that permitting a Market Maker to enter additional order types, except Reserve Orders, in their appointed options class will permit Market Makers additional latitude to conduct business on MRX and effectively compete with other market makers on other options exchanges.                

### 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 [33]                                          and subparagraph (f)(6) of Rule 19b-4 thereunder.[34] 
      ( print page 3199)    
                    A proposed rule change filed under Rule 19b-4(f)(6) [35]                                          normally does not become operative prior to 30 days after the date of the filing. However, Rule 19b-4(f)(6)(iii) [36]                                          permits the Commission to designate a shorter time if such action is consistent with the protection of investors and the public interest. The Exchange has asked the Commission to waive the 30-day operative delay so that the proposal may become operative immediately upon filing. The Exchange states that the proposed rule change will permit Market Makers additional latitude to conduct business on MRX and effectively compete with other market makers on other options exchanges. The Exchange further states that the proposed rule will detail and align the rule text with the system functionality. The Commission believes that waiver of the 30-day operative delay is consistent with the protection of investors and the public interest. Accordingly, the Commission hereby waives the operative delay and designates the proposed rule change as operative upon filing.[37] 

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: (i) Necessary or appropriate in the public interest; (ii) for the protection of investors; or (iii) 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.

For example, displayed quotes were firm only for public customer orders. Since that time, electronic options trading has evolved. With the adoption of trade-through protection under the intermarket linkage, every order must be executed at the best quoted price. Further, ISE has also removed restrictions on non-customer trading.
