FIX Error Reject 102: Too late to cancel

What this error means

Reject code 102 (CxlRejReason) indicates that an OrderCancelRequest arrived too late. The order has already been filled, canceled by the exchange, expired, or is in a terminal state that prevents cancellation.

Common causes

  • Common causes include:

  • 1) Order was already executed before cancel request arrived,

  • 2) Network latency delayed cancel request,

  • 3) Order expired (TimeInForce),

  • 4) Exchange already canceled the order,

  • 5) Order status changed to terminal state (Filled, DoneForDay, etc.).

How to fix it
