Websocket API


  • In the interests of latency, the private Order Channel subscription is now an asynchronous channel and therefore can potentially return order messages not in chronological order. 
  • Order ID is now returned in the success response/ack from the placeorder OP within the data dictionary.


{‘event’: ‘placeorder’, ‘submitted’: True, ‘tag’: ‘1’, ‘timestamp’: ‘1620661554603’, ‘data’: {‘clientOrderId’: ‘1’, ‘marketCode’: ‘BTC-USD-SWAP-LIN’, ‘side’: ‘BUY’, ‘orderType’: ‘LIMIT’, ‘quantity’: ‘0.001’, ‘timeInForce’: ‘GTC’, ‘price’: ‘1000.0’, ‘orderId’: ‘1000005242610’}}


  • For the modifyorder OP the orderID is now persisted and no longer changes when the queue placement of the order changes.
