Hi Keith
I'm not sure that I fully understand your request but from what I think you've
requested I've added a couple of extra outputs. One generates a zero-based plot
that goes positive and negative. The second set of added outputs allow you to
have one colour for positive values, and another colour for negative values.
Regards
Roy

Subject: [EquisMetaStock Group] momentum histogram
I want to show Momentum as a histogram but for some reason, it only
shows all above the line & none below
this is Jose's normalised momentum

Cum(MomNorm)/Cum(IsDefined(MomNorm)));
signals:=
Cross(MomNorm,midpt)-Cross(midpt,MomNorm);
midpt;If(plot=2,signals,MomNorm)
any suggestions welcome as how to show a normal histogram
thanks
