===== MarketData Request Reject =====


==== Rejecting Market Data Requests ====
The **Market Data Request Reject** (Tag `35=Y`) is generated when the T4 FIX API cannot honor a Market Data Request.  
The rejection reason may stem from:
  * Market or exchange not available
  * Lack of user permission
  * Undefined markets
  * Other reasons

The rejection is paired against a previous Market Data Request with the mandatory **MDReqID** (Tag `262`).
