File Name: StochDoubleD.efs

Description:
Stochastic study with two %D lines.

Formula Parameters:
nKLength: Default is 14
nKsmoothing: Default is 1
nDlength1: Default is 9
nDlength2: Default is 18
nUpperBand: Default is 80
nLowerBand: Default is 20

Notes:
The two stochastic studies use the same inputs for nKLength and nKsmoothing.
