Trading Firms (CeFi)
Direct access to the True Markets centralized exchange for firms — order entry and market data over FIX, REST, and WebSocket, with a qualified custodian and institutional-grade compliance. Open to any firm that needs direct market access, including market makers.
This is a different product from the Retail Gateway: different onboarding (KYB, not KYC), different authentication (HMAC or FIX sessions, not JWT), and it isn't served over the public internet.
Getting on
- Access and credentials — KYB, network allowlisting, and the credentials for each surface.
- Account models — principal, omnibus agency, or fully disclosed. Determines how your accounts and clients are structured.
- Manage clients — provision and configure downstream clients, if your model has them.
- Trade over FIX or REST — both are full-featured; FIX is the lower-latency path.
