Place, amend, cancel and query orders on RapidX. Symbols use the unified sym format, so the same call shape works across every supported venue.
Orders move through NEW → OPEN → PARTIALLY_FILLED → FILLED / CANCELLED. Cancellation is asynchronous: the response confirms LTP accepted the request, and the final outcome arrives on the Orders push channel.
The same actions are available over WebSocket with lower latency — see Orders under Trading · WebSocket.
