I have been trying for two days to make this work, just
have not made it work,so now asking for help.
(V < (ref(V,-1)) then
NVI = I + (((C - ref(C,-1) / ref(C,-1)))
If (V >= ref(V,-1)) then
NVI = I
Where:
C = Today's closing price
ref(C,-1) = Yesterday's closing price
I = Yesterday's Negative Volume Index
NVI = Today's Negative Volume Index
V = Today's volume
ref(V,-1) = Yesterday's volume
________________________________________________________
this is what I have done up to now.
I= Cum(IIf(V<Ref(V,-1),ROC(C,1),0));
MA1 = NVI()<= I + (C -Ref(C,-1) / Ref(C,-1));
MA2=NVI() <= I;
col = IIf( V < Ref( V, -1), colorGreen, colorRed );
Col2= IIf(V > Ref(V,-1),colorGreen, colorRed );
Plot(V, "Price",Col, MA1, styleBar );
Plot( V, "Price",Col2, MA2, styleBar );
