Important note: If you specify a wrong
market parameter (i.e. the market you specified is not the market in which your order was placed), your request to cancel will succeed, but have no effect on your order (e.g. your order may remain open).
In order to cancel an inflight order (one for which you have not received an ack yet), you can supply the
market body parameter in an attempt to locate and cancel the order prior to placement.
For optimal latency, it is advised to specify
market in your request.
