Heiken Ashi Chart Confusion

[wackytacky]

Hi all,
I have a small doubt.
Whenever we change Chart type to Heiken Ashi, the values of all Indicators changes completely. For instance the value of a particularity day in daily chart on any indicator will be different for candlestick chart than Heiken Ashi chart.
The Doubt is
The Indicators like MACD or SuperTrend ,etc, during their calculation using OHLC, Do they use Heiken Ashi's OHLC if on Heiken Ashi or does they take normal OHLC?

I was writing SuperTrend and Heiken Ashi Combination in python using Pandas.
Should I use Heiken Ashi's OHLC to write SuperTrend Strategy or with normal?
