I'd like to ask for some help converting this Double Smoothed Stochastic
formula(Bressert) from the eSignal language to easy language(.ela). Here it
is in eSignal format:
Oscillators > DSS Bressert (Double Smoothed
Stochastic) [eSignal EFS Indicators]
Download: dss_bressert.efs
Category: Indicator > Oscillators
Description:
Double Smoothed Stochastics (DSS) is
designed by William Blaw. It attempts to combine moving average methods with
oscillator principles.
Inputs:
pds - number of bars to calculate trigger
slw - number of bars to calculate trigger
triggerLen - trigger`s length
emalen - number of bars to calculate EMA
EFS Code:
