Origin of correcting algorithm :
Dr. Alexander Uhl invented a method that he used to filter the moving average and to check for signals. Originally it was used at simple moving average
This indicator :
This indicator is using the modified “correcting” method. Instead of using standard deviation for calculation, it is using EMA deviation (originally published here : EMA deviation) and is applied to super smoother (originally published here : Super smoother)
Usage :
You can use the change of color as signals
