File Name: Stochastic_Histogram.efs


Description:
Plots a histogram of the difference between the %K and %D lines.


Formula Parameters:
nInputPercentK1: Default is 14
nInputPercentK2: Default is 1
nInputPercentD: Default is 3

Notes:
Default is for a "Fast Stochastic", but adjusting the nInputPercentK2 to 3 would make this a "Slow Stochastic".
