indi reload/repaint

GREETINGS to the more advanced programmers... as I am not worthy I would like some help with a multiple-TF indi problem.

mtf_3xRSI which is a triple-timeframe RSI is giving me a problem. It's not that it repaints, to my knowledge. The problem comes when i leave the chart up and come back to it after some time (say an hour). When i reload the template with the indi, the indi changes and replots a little differently.

Can anyone explain what is happening? I'm only novice but I want to learn and am willing to get my hands dirty in the MetaEditor. Thanks in advance..

Maybe I can clarify my question-- How do you program the indi to recalc the last X number of bars, not just the current bar ? When working with higher timeframes, it seems necessary to recalc more than just the current bar.

limit=Bars; --recalcs every bar and bogs down the computer

but:

counted_bars=IndicatorCounted()

limit=Bars-counted_bars; ----is not recalculating enough bars


Thanks.
