title: Binance futures ACCOUNT_UPDATE stream trade via websocket problem?
body: <p>I am getting no response from the Binance api when executing the following code, is there anything that I could have missed here?</p>
  <pre><code>import json
  import websocket
  
  
  socket='wss://fstream.binance.com/ws'
  
  
  def on_open(ws):
      print(&quot;opened&quot;)
      subscribe_message = {
          &quot;method&quot;: &quot;SUBSCRIBE&quot;,
          &quot;params&quot;:
          [
           &quot;ACCOUNT_UPDATE&quot;
           ],
           &quot;id&quot;: 1
           }
  
      ws.send(json.dumps(subscribe_message))
  
  def on_message(ws, message):
      print(&quot;received a message&quot;)
      print(json.loads(message))     
  
  def on_close(ws):
      print(&quot;closed connection&quot;)        
  
  ws = websocket.WebSocketApp(socket, on_open=on_open, on_message=on_message, on_close=on_close)
  ws.run_forever()
