Proposed Rule Change Relating to Alternative Trading System Volume and Trading Information

Financial Industry Regulatory Authority, Inc. (“FINRA”) is filing with the Securities and Exchange Commission (“SEC” or “Commission”) a proposed rule change to (i) delete from the FINRA rulebook Rule 4552, which requires each alternative trading system (“ATS”) that has filed a Form ATS with the SEC to report to FINRA weekly volume information and number of trades regarding equity securities transactions within the ATS; (ii) amend Rules 6110 and 6610 to add provisions regarding FINRA’s publication of ATS volume and trade count information for equity securities, including information similar to what is currently reported by ATSs pursuant to Rule 4552 as well as information regarding ATS block transactions; and (iii) amend Rules 6183 and 6625 to require ATSs seeking an exemption from FINRA trade reporting rules to provide FINRA with a link to a publicly-available website that displays their weekly equity volume information in a format substantially similar to that used by FINRA.
