Here's a nice little update on that. Normally the ADX calculations are calculated with the moving average "Running Moving Average (RMA)". Under the settings you can now select different MA types via the option "Type of Moving Average". With this new, interesting possibilities are then available.
Selectable MA variants:
"COVWMA", "DEMA", "EMA", "EHMA", "FRAMA", "HMA", "KAMA", "RMA", "SMA", "SMMA", "VIDYA", "VWMA", "WMA"
