Schedule cancellation of every open order in a league. This endpoint dispatches asynchronously — it acknowledges with { ordersReceived: true } immediately and the cancels happen in the background. If you need to know which orders were cancelled, follow up with Get unmatched orders or subscribe to the user feed on the WebSocket Streaming API.
