title: Why does this node-red configuration for websockets work?
body: <p>I have created a node-red websocket connection that sends the following JSON message </p>
  
  <p>{"event":"subscribe","channel":"trades","pair":"BTCUSD"}</p>
  
  <p>to the Bittrex websocket:</p>
  
  <p>wss://api.bitfinex.com/ws</p>
  
  <p><a href="https://i.stack.imgur.com/c3wgY.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/c3wgY.png" alt="enter image description here"></a>
  I also created a websocket that listens to the same address</p>
  
  <p>For some reason it works. I'm confused since there is no relationship that I can see between the websocket that sends the payload with the one that receives the data and sends it to debug (green).</p>
  
  <p>Does anyone have any insights on this please?</p>
