title: In Pine not possible to loop over different confirguation of a script?
body: <p>I would like to test my strategy with on different timeframes, trading pairs and parameter values.</p>
  <p>For this I would like to build a script with nested loops, a bit like this (pseudo code):</p>
  <pre><code>for pair in [EURUSD, BTCUSD, ETHBNB]:
  
      for tf in [5m, 15m, 1h, 4h]
  
          for va1 in [1, 2, 3, 4]:
  
              for va2 in [0.2, 0.5]:
  
                  perform_strategy()
                  write results somewhere
  </code></pre>
  <p>But after having read the doc I am afraid this is not possible with Pine. Could someone confirm ?</p>
  <p>Thanks a lot</p>
