Connectivity
TXSE’s primary matching engine is located in Equinix NY6 in Secaucus, NJ, with latency equalization across NY4, NY5, and NY6. Customers outside these buildings will experience additional latency. The disaster recovery (DR) matching engine is hosted in Equinix DA11 in Dallas, TX.
Customers may connect to DR either directly to DA11 or through TXSE infrastructure at 350 E. Cermak in Chicago. Cermak connections will have traffic backhauled to DA11 over redundant TXSE circuits. Backhaul from Cermak to the production data center is not available.
Connectivity to both production and DR environments is available through cross-connects, circuits, or approved extranet providers. Cross-connects are limited to customers within the respective Equinix campuses, must terminate in a customer cage, and cannot connect directly to rooftop infrastructure.

The Sandbox is not yet live, but interested parties should contact TXSE Market Operations at tradingoperations@txse.com to register for early access and receive updates on its availability. Industry-wide production testing is slated to begin with weekend sessions in October, continuing monthly through launch.

Technical specifications
TXSE will offer binary and FIX order entry protocols, giving members flexible, high-performance access to the market—and distinctive order type features to optimize trading strategies.
RAKE TCP is a TCP-based protocol that ensures reliable, in-order delivery of Exchange messages, while Member messages are sent without delivery guarantees. Higher-level protocols handle uniqueness, and most servers process one Member message at a time.
RAKE UDP is a simple message framing protocol for sending messages from the Exchange to Members only. Typically used for market data, although it is also payload agnostic.
TXSE's drop copy specifications are not yet finalized and will be completed and posted at a later date.
Market data
TXSE's Market Data FEED is designed to deliver comprehensive, real-time, low-latency market data for all trading activities on the Texas Stock Exchange.
Fees
TXSE plans to offer introductory rates, which will be waived in most cases.
