On August 13, the Financial Industry Regulatory Authority (FINRA) issued Regulatory Notice 18-25 to remind Alternative Trading Systems (ATS) to evaluate their supervisory systems to ensure compliance with their supervision obligations, including, without limitation, with respect to business continuity, recordkeeping, Regulation ATS, Regulation NMS, Regulation SHO and the SEC’s Market Access Rule, to the extent applicable. As a general matter, consistent with existing supervision obligations, FINRA expects that an ATS’s supervisory system be reasonably designed to identify “red flags,” including potentially manipulative or non-bona fide trading that occurs on or through its systems.

The regulatory notice is available here.
