      Hello,

      have an issue with accessing all feeds of self.datas in the indicator.

      I added 11 data feeds to cerebro and ran the strategy, if I set a breakpoint inside the strategy, self.datas contains all the 11 feeds but in my indicator, self.datas contains only the first feed.

      I add all datafeed with adddata with a different name and can loop trough them in the strategy correctly.

      Thank you

        @kumzy highly likely the indicator is applied only once for the first data feed. Hard to say more without seeing the actual code.

          @ab_trader Thought that the indicators worked like the strategy where self.datas is accessible. Instead only the first is accessible. You were right
