Cancel Replace Order

PUT https://api.poloniex.com/orders/{id}
PUT https://api.poloniex.com/orders/cid:{clientOrderId}

Cancel an existing active order, new or partially filled, and place a new order on the same symbol with details from existing order unless amended by new parameters. The replacement order can amend price, quantity, amount, type, timeInForce, and allowBorrow fields. Specify the existing order id in the path; if id is a clientOrderId, prefix with cid: e.g. cid:myId-1. The proceedOnFailure flag is intended to specify whether to continue with new order placement in case cancelation of the existing order fails. Please note that since the new order placement does not wait for funds to clear from the existing order cancelation, it is possible that the new order will fail due to low available balance.
