Does anyone have a moving average function where the average is based off a time period, eg 30m chart, and then if you display a 5 min chart, the value of the moving average is expanded correspondingly so you can see where price is on a 5min chart relative to a moving average off a 30min chart

It will save having several ma's loaded each with their own "when to display" rules

I wrote one .. but it has a display error
