Our Form ATS

In order to legally operate as an Alternative Trading System ("ATS"), trading venues must submit a Form ATS to the SEC.

This document is meant to describe how that market operates, including who is able to participate, the types of securities traded, pricing, order types supported, matching logic, and order book priority.

We share below our effective Form ATS (redacted to protect partner and subscriber information). It's part of our effort to set new standards for transparency in our industry.

Form ATS, effectively registered as of September 11, 2014
