Beginning today, FINRA is expanding its ongoing transparency initiative for the over-the-counter (OTC) equity market by publishing new data about OTC trading volume occurring outside of alternative trading systems (ATSs). The data is available free of charge on FINRA’s website.

For the first time, FINRA will publish:

• Monthly aggregate block-size trading data for OTC trades in National Market System (NMS) stocks executed outside an ATS, on a one-month delayed basis; and
• Aggregate non-ATS volume for each firm, by eliminating the de minimis exception for firms executing fewer than, on average, 200 non-ATS transactions per day during the applicable reporting period.

“Today marks another important step in our longstanding effort to enhance market transparency,” said Thomas Gira, Executive VP of Market Regulation and Transparency Services. “Publication of the additional data will be beneficial to securities firms and the general public, providing greater visibility into OTC trading activities.”

Additional details about today’s initiative are available in Regulatory Notice 19-29 and in a Technical Notice highlighting the new data that will be published.
