July 23, 2013.
Pursuant to Section 19(b)(1) of the Securities Exchange Act of 1934 (the “Act”) 
and Rule 19b-4 thereunder,
notice is hereby given that on July 9, 2013, Miami International Securities Exchange LLC (“Exchange” or “MIAX”) 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 self-regulatory organization. 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 delay the operative date of a recent change to Rule 506. There are no proposed changes to the rule text.
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.Start Printed Page 45587
A. Self-Regulatory Organization's Statement of the Purpose of, and Statutory Basis for, the Proposed Rule Change
On April 24, 2013, the Exchange filed a rule change, which became effective on that date, to amend Rule 506 to make available to subscribers of its MIAX Top of Market (“ToM”) data feed the quantity of Priority Customer contracts included in the MIAX Best Bid and Offer (“MBBO”) disseminated by the Exchange.
The proposed rule change in that filing became effective on filing and was set to become operative by July 10, 2013. Pursuant to the previously filed rule change, the Exchange announced via a Regulatory Circular an implementation date of July 10, 2013.
The purpose of this rule filing is to delay the operative date of the change to Rule 506 in rule filing SR-MIAX-2013-18 until MIAX has completed the necessary changes to its ToM data feed. The Exchange will announce the implementation date of the proposed rule change in a Regulatory Circular to be published no later than 30 days following the publication of the notice in the Federal Register. The implementation date will be no later than 30 days following the publication of the Regulatory Circular announcing publication of the notice in the Federal Register.
2. Statutory Basis
The Exchange believes that the proposed rule change is consistent with Section 6(b) of the Act,
in general, and furthers the objectives of Section 6(b)(5) of the Act,
in particular, because 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, and to remove impediments to and perfect the mechanism of a free and open market and a national market system. Additionally, the Exchange believes the proposed rule change is consistent with the Section 6(b)(5) requirement that the rules of an exchange not be designed to permit unfair discrimination between customers, issuers, brokers, or dealers.
In particular, the Exchange believes that delaying the operative date of this change to its ToM data feed will protect investors because it will provide the Exchange with sufficient time to complete its system work and perform sufficient testing that is necessary to ensure that this new feature will function as described in rule filing SR-MIAX-2013-18.
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. This proposed rule change delays the operative date of the change to the Exchange's ToM data feed, and the Exchange will announce the new operative date in a Regulatory Circular that is available for all Exchange members.
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 Exchange has filed the proposed rule change pursuant to Section 19(b)(3)(A)(iii) of the Act 
and Rule 19b-4(f)(6) thereunder.
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 prior to 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 and Rule 19b-4(f)(6)(iii) thereunder.
A proposed rule change filed under Rule 19b-4(f)(6) 
normally does not become operative prior to 30 days after the date of the filing. However, pursuant to Rule 19b-4(f)(6)(iii),
the Commission may 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 to allow the Exchange sufficient time to update and test its system to accommodate the technical functionality that was the subject of the recent proposed rule change discussed above. The Commission finds that such waiver is consistent with the protection of investors and the public interest, because without such waiver, the proposed delay of the implementation date could not become operative for 30 days, and pursuant to the Exchange's previously issued Regulatory Circular,
the amendment to Rule 506 would therefore become operative on July 10, 2013. As noted, the Exchange has represented that it needs additional time to develop the technical functionality needed for that rule change. Accordingly, the Commission hereby grants the Exchange's request and designates the proposal operative upon filing.
At any time within 60 days of the filing of such 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.
