Here is upgraded work of this indicator combo(+supertrend).
In this old version is used ATR to calculate supertrend and it is not working well through instruments and timeframes, you must handle multiplier from
0.001 to 999.In this new function/version is different way to calculate range for supertrend calculation and not need it adjust to timeframe/instrument what you want trade.
Rsi indicator for test with this new supertrend as a signal.
