what happened to the order you just sent

if you want to check what happened to the order you must send ProtoOAOrderListReq, then server sends back a list of orders, now in that list you can find your order

you might ask well how can I find my order, well, there are two ways, one way is that you can find it based on time of the order, which you can use the utcLastUpdateTimestamp field of an order in the list of orders returned by server

anoter way is to find it using a user-provided orderId, here you must provide a clientOrderId field when you are sending the ProtoOANewOrderReq message, this way you already know the id of the order that you want to find (in the list of orders returned by the server)
