Theory :
The original of deviation scaled ma was originally published here : Deviation Scaled MA with some more explanation. That original is using what Ehlers calls a “filer” which is simply a difference between close and a close of 2 bars ago. That is all OK – as long as you use close price … or as long as you use it to smooth price …
This version :
It corrects the usage of filter and makes it possible to apply deviation scaled MA to any value (does not matter if it is a price or some other value)
Usage :
It can be used as any other average now
