US-registered broker-dealers that operate Alternative Trading Systems will have to report volume information, by security, to FINRA weekly. The first report, for the week of May 12, 2014, is due May 28, 2014. ATS will, by November, require their own separate Market Participant Identifier (or “MPID”).

Summary of New Rules:

On January 17, 2014, the US Securities and Exchange Commission (“SEC”) voted to approve a FINRA rule proposal that significantly changes the regulatory landscape for broker-dealers that operate as alternative trading systems, or ATSs.
