Here's another CMO formula.
It incorporates an idea from Roy inorder to avoid the Div by zero
error. Also a link to another Karnish ppt presentation.

{Chande Momentum Oscillator}
Periods:=Input("Periods",1,200,3);
Up:=Sum((C-Ref(C,-1))*(C>Ref(C,-1)),Periods);
Down:=Sum((Ref(C,-1)-C)*(C<Ref(C,-1)),Periods);
DS:=Up+Down;{divisor sum}
ChandeMo:=(Up-Down)/(DS+(DS=0))*100;
ChandeMo;{end}
