Rudolf,
Whew, I'll study what you shared with me and get back with you on any
questions. I was looking more into combining the two "canned" indicators
that came with MetaStock..... as an example:
Lb:=Input("Look-Back Periods?",3,100,13);
ROC( LinRegSlope(C,Lb),Lb,$)
Does this differ from your usage below? I will analyze what you have
shared with me and perhaps some of it will soak in <g>.
Thank you!
Best wishes,
Adam Hefner.
