Cancel Order
Introduction
An order can be cancelled from the API with the functions EClient.cancelOrder and EClient.reqGlobalCancel.
EClient.cancelOrder can only be used to cancel an order that was placed originally by a client with the same client ID (or from TWS for client ID 0).
EClient.reqGlobalCancel will cancel all open orders, regardless of how they were originally placed.
