In preparation for our target launch date of July 6, 2026, TXSE held its 3rd end-to-end SIP test this past Saturday. Thank you to those firms that participated.

To those firms that have not ordered connectivity or started testing with us, we have more testing opportunities coming up! We just added a production testing day for this Saturday, May 16. If you have any questions or are encountering any issues, please let us know. This is a new matching engine and environment, so the testing is valuable to both you and TXSE.

In addition to May 16 and the previously scheduled industry-wide SIP test dates already scheduled for June 6 and June 27, TXSE will also open the production environment on, May 30, and June 13, allowing firms to test order entry, drop copy, and market data directly with TXSE.
