Heikin Ashi Values in existing Indicators

Hi

I try to integrate Heikin Ashi candles into the calculation of different Indicators. As Heikin Ashi candles have different values than the real candles, calculating those Indicators would create different values.

For example the Indicators.DirectionalMovementsSystem or the Exponential Moving Average are things I would like to calculate with Heikin Ashi values.

Is this even possible or do I have to write all the functions by myself?

Thank you for your help.
