Firstly the documentation example mentions that 'trading_symbol' will be returned whereas the key is 'tradingsymbol'.
Then 'filled_quantity' is also returned, the documentation is silent about this, so can we reliably use this?
Then documentation for the 'status' says that there may be other values as well. The documentation should atleast state all possible values so that code at our side can handle the situations appropriately.
Another issue faced while using websockets was that whenever an order is placed, the websocket returns some data that does not conform to the format of messages expected. This is most unexpected, are you also trying to send some response of the order placed via web sockets?
