Cancel Order

Requires an authenticated websocket connection. Please also subscribe to the User Order Channel to receive push notifications for all message updates in relation to an account or sub-account (e.g. OrderClosed etc......).

This command can also be actioned via the trading GUI using the Cancel button next to an open order in the Open Orders blotter for both Spot and Derivative markets.
