Adaptive MA Difference constructor [lastguru]A complimentary indicator to my Adaptive MA constructor. It calculates the difference between the two MA lines (inspired by the Moving Average Difference (MAD) indicator by John F. Ehlers). You can then further smooth the resulting curve. The parameters and options are explained here: 
The difference is normalized by dividing the difference by twice its Root mean square (RMS) over Slow MA length. Inverse Fisher Transform is then used to force the -1..1 range.
Same  Postfilter  options are provided as in my Adaptive Oscillator constructor:
 
   Stochastic  - Stochastic
   Super Smooth Stochastic  - Super Smooth Stochastic (part of MESA Stochastic ) by John F. Ehlers
   Inverse Fisher Transform  - Inverse Fisher Transform
   Noise Elimination Technology  - a simplified Kendall correlation algorithm "Noise Elimination Technology" by John F. Ehlers
   Momentum  - momentum (derivative)
 
Except for Inverse Fisher Transform, all  Postfilter  algorithms can have  Length  parameter. If it is not specified (set to 0), then the calculated Slow MA Length is used.
