T3 Trading Group, LLC has agreed to pay a fine of $175,000 as a part of a settlement with the Financial Industry Regulatory Authority (FINRA).

From April 2020 to April 2025, T3 failed to comply with its obligation to publish quarterly reports concerning the firm’s handling of customer orders in National Market System (NMS) securities.

T3 failed to publish any such reports from April 2020 to July 2021. Thereafter, from July 2021 to April 2025, the firm published quarterly reports that contained none, or very little, of the information that the firm was required to disclose.

As a result, the firm violated Rule 606(a) of Regulation NMS under the Securities Exchange Act of 1934 and FINRA Rule 2010.

In addition, from January 2020 to the present, T3 has failed to establish and maintain a supervisory system, including written supervisory procedures (WSPs), reasonably designed to achieve compliance with Rule 606(a) of Regulation NMS.

Due to this, the firm has violated FINRA Rules 3110 and 2010.

For these violations, T3 is censured, fined $175,000, and consents to an undertaking to take corrective action.

T3 has been a FINRA member since October 2019. The firm is headquartered in New York, New York, has four branch offices, and employs approximately 200 registered representatives. The firm primarily engages in day trading and proprietary trading in exchange-listed equity securities, equity option contracts, and futures. Since January 2020, the firm has also maintained a retail day-trading business line.
