Ketner channel is calculated as SMA (Simple Moving Average) +- ATR (Average True Range)
This version is deviating from that. It allows you to use one of the 4 average types :
- simple moving average (SMA)
- exponential moving average (EMA)
- smoothed moving average (SMMA)
- linear weighted moving average (LWMA)
and instead of using “regular” ATR it uses the smooth ATR (which is much smoother and faster from the regular ATR)
