          - [Release No. 34-74307; File No. SR-MIAX-2015-11]

                    Pursuant to Section 19(b)(1) of the Securities Exchange Act of 1934 (the “Act”),[1]                                          and Rule 19b-4 thereunder,[2]                                          notice is hereby given that on February 18, 2015, Miami International Securities Exchange LLC (“MIAX” or “Exchange”) filed with the Securities and Exchange Commission (“Commission”) the proposed rule change as described in Items I and II below, which Items have been prepared by the Exchange. The Commission is publishing this notice to                           ( print page 10197)                        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 Exchange Rule 530 to extend the pilot period for the treatment of erroneous transactions during a Limit or Straddle State.

                    The text of the proposed rule change is available on the Exchange's Web site at                     *http://www.miaxoptions.com/​filter/​wotitle/​rule_​filing,*                     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 Rule 530 (Limit Up-Limit Down) in order to extend the pilot period for the treatment of erroneous transactions that occur in a Limit or Straddle State until October 23, 2015.

                    Exchange Rule 530(j) provides for the treatment of erroneous transactions occurring during Limit and Straddle States. Specifically, once an NMS Stock has entered a Limit or Straddle State, the Exchange will nullify a transaction in an option overlying such an NMS Stock as provided in the Rule 530(j). This provision was adopted for a one year pilot period beginning on the date of the implementation of the Plan to Address Extraordinary Market Volatility Pursuant to Rule 608 of Regulation NMS, April 8, 2013.[3]                                          The Exchange previously extended the pilot period for Rule 530(j) until February 20, 2015.[4]                                          The Exchange now proposes to extend the pilot period for Rule 530(j) until October 23, 2015 in order to allow the Exchange and the Commission additional time to collect and analyze data regarding the impact of Rule 530(j) on liquidity and market quality in the options markets.                

To assist the Commission in its analysis, the Exchange will provide the Commission and the public with data and analysis during the duration of the pilot in order to evaluate the impact of Limit and Straddle States on liquidity and market quality in the options markets. Specifically, by May 29, 2015, the Exchange represents that it shall provide the Commission and the public assessments relating to the impact of the obvious error Rules during Limit and Straddle States that (i) evaluate the statistical and economic impact of Limit and Straddle States on liquidity and market quality in the options markets; and (ii) assess whether the lack of obvious error rules in effect during the Straddle and Limit States are problematic. Additionally, each month during the pilot period the Exchange shall provide to the Commission and the public a dataset containing the data for each Straddle and Limit State in optionable stocks. For each stock that reaches a Straddle or Limit State, the number of options included in the dataset can be reduced by selecting options in which at least one (1) trade occurred on the Exchange during the Straddle or Limit State. For each of those options affected, each data record should contain the following information: (i) Stock symbol, option symbol, time at the start of the straddle or limit state, an indicator for whether it is a straddle or limit state; and (ii) for activity on the exchange—(A) executed volume, time-weighted quoted bid-ask spread, time-weighted average quoted depth at the bid, time-weighted average quoted depth at the offer, (B) high execution price, low execution price, (C) number of trades for which a request for review for error was received during Straddle and Limit States, (D) an indicator variable for whether those options outlined above have a price change exceeding 30% during the underlying stock's Limit or Straddle state compared to the last available option price as reported by OPRA before the start of the Limit or Straddle state (1 if observe 30% and 0 otherwise) and another indicator variable for whether the option price within five minutes of the underlying stock leaving the Limit or Straddle state (or halt if applicable) is 30% away from the price before the start of the Limit or Straddle state.

#### 2. Statutory Basis

                    MIAX believes that its proposed rule change is consistent with Section 6(b) of the Act [5]                                          in general, and furthers the objectives of Section 6(b)(5) of the Act [6]                                          in particular, 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, 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. Specifically, the proposal supports the objectives of perfecting the mechanism of a free and open market and the national market system because it promotes uniformity across markets concerning when and how to halt trading in all stock options as a result of extraordinary market volatility. In addition, the Exchange believes that the extension of the pilot will help ensure that market participants continue to benefit from the protections of the Limit Up-Limit Down Rules which will protect investors and the public interest while allowing the Exchange and the Commission additional time to collect and analyze data regarding the impact of Rules on liquidity and market quality in the options markets.                

### 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. The proposed changes are being made to extend the pilot program that provides for how the Exchange shall treat orders and quotes in options overlying NMS stocks when the Limit Up-Limit Down Plan is in effect and will not impose any burden on competition while providing certainty of treatment and execution of options orders during periods of extraordinary volatility in the underlying NMS stock, and facilitating appropriate liquidity during a Limit State or Straddle State.                          ( print page 10198)    

### 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

                    Because the 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 if consistent with the protection of investors and the public interest, the proposed rule change has become effective pursuant to Section 19(b)(3)(A) of the Act [7]                                          and Rule 19b-4(f)(6)(iii) thereunder.[8] 

                    The Exchange has asked the Commission to waive the 30-day operative delay so that the proposal may become operative immediately upon filing. The Commission believes that waiving the 30-day operative delay is consistent with the protection of investors and the public interest, as it will allow the obvious error pilot program to continue uninterrupted while the industry gains further experience operating under the Plan to Address Extraordinary Market Volatility, and avoid any investor confusion that could result from a temporary interruption in the pilot program. For this reason, the Commission designates the proposed rule change to be operative upon filing.[9] 

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.
