The indicator you posted HMA_Bands (attached) does not have the HMA setting.
It has 8 settings for the moving average (bands method) but it does not include HMA.
I have tried to duplicate the HMA with various settings on the 8 moving averages but cannot get it to match.
The HMA Bands indicator I originally posted does reproduce the HMA setting whereas the HMA_Bands indicator (attached) does not.
Thanks
