[amibroker] Help with AD Ratio

["smithkt9675" <SmithKT1@xxxxxxxxx>]

Hello, I'm trying to plot the Advance/Decline Ratio so that advancers 
show up 3:1 for example, and decliners show up as -3:1, so that 
declining days appears as a negative breadth thrust and advancers 
positive...all along a zero line in histogram form.  The formula 
looks right, but when compared to a source I'm trying to replicate 
the figures look off.  Please advise if I should tweak the formula.  
I'm using Yahoo data.  Thank you very much.

symz="~Advancers";
symy="~Decliners";
Advance=Close>Ref(Close,-1);
Advance1=Advance>0;
Decline=Close<Ref(Close,-1);
Decline1=Decline>0;
IIf(Advance1>0,AddToComposite(Advance1,symz,"C"),0);
IIf(Decline1>0,AddToComposite(Decline1,symy,"C"),0);

AD1=Foreign("~Advancers","C");
DC1=Foreign("~Decliners","C");

ADRatio= IIf(DC1>AD1,(DC1*-1)/AD1, AD1/DC1);

Buy=0;
Filter = 1;

GraphXSpace = 2;
Plot(ADRatio,"AdvanceDeclineRatio",colorDarkBlue,styleHistogram);

Plot(0,"",colorBlack);
Plot(3,"",colorGreen);
Plot(-3,"",colorRed);

Title="Advance/Decline Ratio";
