Is it Possible to Write an Indicator that shows a 30min moving average as a line on a 5 min chart?

Very basic example

If you're showing a higher timeframe indicator on a lower, this wont show any history - you just get a straight line when you first put it on the chart

Does show how much the leading edge of almost all indicators does waggle around in live trading...

it's very simple just put MA * 6 on 5 min chart == ma 30 min chart

for example if u want 10 Ma simple on 30 min chart, on 5 min chart put 60 MA simple (30/5 =6 - 10*6 = 60)
