Form ATS-N Filings and Information

Rule 304 of Regulation ATS requires alternative trading systems (“ATSs”) that trade NMS stocks (“NMS Stock ATSs”) to publicly file with the Commission an initial Form ATS-N, amendments to initial Form ATS-N, and notices of cessations of operations.[1] Form ATS-N requires disclosures about the manner of operations of the NMS Stock ATS and the ATS-related activities of the broker-dealer operator and its affiliates, among other things.

An initial Form ATS-N will become effective, unless declared ineffective, upon: (1) the earlier of the completion of review by the Commission and publication via posting on the Commission’s website, or (2) the expiration of the review period, or if applicable, the end of the extended review period. The Commission may declare an initial Form ATS-N ineffective after notice and opportunity for a hearing if it finds such action is necessary or appropriate in the public interest, and is consistent with the protection of investors. A Form ATS-N amendment may be declared ineffective if the Commission finds that such action is necessary or appropriate in the public interest, and is consistent with the protection of investors. In addition, the Commission may suspend for a period not exceeding twelve months, limit, or revoke an NMS Stock ATS’s exemption from the definition of “exchange” pursuant to Rule 3a1-1(a)(2).
