I'm trying to understand how Ehlers smoothed the RSI in his S&C magazine article I think in 2002(?) already. He calls it the RSI smoothing trick, and included an "EasyLanguage" script.
I'm trying to code this into a simple mt4 indicator, but can't figure out what he uses to calculate the smoothing coefficient, and where he uses it.
Someone must have implemented this in mql but all I can find is the inverse fisher transform smoothing etc which is a bit complicated for me at this point.
Can anybody point me in the right direction?
Thanks

I have the pdf, and Mladen's approach seems a bit different than what Ehlers described.
I see he uses weighted moving averages to calculate the coefficient, while it seems to me in Ehlers' description the coefficient is calculated by weighted closes.
Maybe I'm misunderstanding the whole concept.

#4Replying to my own post but I figured it out at last. You have to smooth all prices (ie 0 to rates_total) and then calculate the RSI from the smoothed data. MLaden uses a 1 period iMA function which is the same as using the closes, but it is easier to pass the input parameters that way.DocYummy77 wrote: ↑Mon Mar 01, 2021 7:19 amThank you very much MrTools!
