title: authenticating en external client in Pine script
body: <p>I'm in the process of writing an indicator that has Open Interest as a confirmation. However, in order to retrieve the Open Interest Chart, I need to be authenticated using the Coinalyze API (as this information is not freely available on Tradingview.com). However first off all, I can't see in Pinescript's documentation whether authenticating with a username/password combination is possible in the first place.</p>
  <p>Does anybody know if this is doable? I also haven't found the api method to authenticate or retrieve the open interest data either, but knowing if authentication is possible in the first place would be helpful first.</p>
  <p>Thanks!</p>
