====== T4 FIX API OVERVIEW ======

The T4 FIX API 4.0 provides electronic trading access to futures markets through the [[http://www.fixprotocol.org|Financial Information eXchange (FIX) Protocol]] 4.2 with T4-specific enhancements.

===== Connection Requirements =====
  * SSL-encrypted TCP socket connection
  * Authentication via FIX Logon

To connect your application to T4 you would need to establish an SSL connection to the appropriate system below:

^ System              ^ URL                          ^ Port  ^
| Simulator           | uhfix-sim.t4login.com          | 10443 |
| Live                | uhfix.t4login.com              | 10443 |




===== FIX Session Lifecycle =====
  1. [[developers:fixapi:logon|Logon]] - Authentication and session configuration
  2. **Message Exchange** - Trading and market data
  3. [[developers:fixapi:logout|Logout]] - Session termination

Optional: Multiple [[developers:fixapi:traderlogon|Trader Logons]] per physical connection

===== Message Integrity Requirements =====
  * SOH delimiter (ASCII 001) between fields
  * Sequential message numbering (Tag 34)
