TXSE May 30 Industry Test
Dear TXSE Member,
This is a reminder that TXSE will conduct an industry-wide production test this Saturday as part of our ongoing preparations for our launch on July 6, 2026. As previously communicated, our July 6 launch will be limited to a defined set of test symbols. The full symbol rollout will occur in phases following launch.
TXSE will publish to the SIPs during this test session. Firms are encouraged to participate in testing order entry, drop copy, and market data connectivity directly with TXSE and through the SIPs.
If you have not yet ordered connectivity or begun testing with us, we strongly encourage participation. As this is a new matching engine and environment, testing remains valuable to both member firms and TXSE.
How to Participate
- Confirm participation by emailing marketops@txse.com
- Ensure cross connects and logical ports are in place
Test Overview
Coverage includes order entry, cancel, replace, mass cancel, drop copy flows, as well as market data subscriptions (FEED) and SIP publishing.
