Ryan, glad to hear you are working with the Ehlers. When it comes to Ed’s “drivers” and “builders” I sort of fit in between as maybe a “part-time weekend builder”.
Another one I like and use that Mel translated is the eFourier. I usually include it on a chart along with the Spectrum heat map to find the dominant cycle and then edit the eFourier for that cycle. Would be nice if somebody could program that so the dominant cycle could be built in the indicator. That is builder work that I could never do on a weekend <:)
