[amibroker] Re: Controlling GraphZOrder on Bar by Bar Basis

["Fred" <ftonetti@xxxxxxxxxxxxx>]

Oh I get it ...

Try this ...

A1 = AMA(C, 2 / (12 + 1));
A2 = AMA(C, 2 / (26 + 1));

MCD1 = A1 - A2;
MCD2 = AMA(MCD1, 2 / (9 + 1));

Plot(IIf((MCD1 < MCD2 AND MCD1 < 0) OR (MCD1 > MCD2 AND MCD1 > 0), 
MCD2, MCD1), "1", IIf(MCD1 < MCD2, colorRed,  colorBlue), 
styleHistogram); 
Plot(IIf((MCD1 < MCD2 AND MCD1 < 0) OR (MCD1 > MCD2 AND MCD1 > 0), 
MCD1, MCD2), "2", IIf(MCD1 < MCD2, colorBlue, colorRed),  
styleHistogram);
