I was wondering if anyone knows if there is an indicator that makes moving average lines visable on lower timeframes?For example I want to set MA 20 on h4, but I want that line to be visable on for example m30?
Those are called multi-time-frame indicators (MTF.) Look in the codebase.
For moving averages, the 20/H4 is close to the 160/M30. Not worth the trouble.
