Kyle,
Take a look at the code below that I have
been working on with another member. It’s a bit different approach from
yours, based on Volume. It does a plot of the ADRatio of Volume. You might be
able to get some ideas from it.
Enjoy,
Donald F Lindberg
------------------------ Begin Code
-------------------------------
UpVol = ValueWhen(C
> Ref(C,-1), V);
DownVol = ValueWhen(C
< Ref(C,-1), V);
UPV=Sum(UpVol,1);
DNV=Sum(DownVol,1);
TOTVOL = (UPV+DNV);
Period = Param("Period",3,2,10,1);
UpVolAvg = EMA( UPV, Period ) ;
DownVolAvg = EMA( DNV, Period ) ;
ADRatio= IIf(DNV>UPV,(DNV*-1)/UPV,
UPV/DNV);
Plot(UPV,"UpVolume", colorGreen,styleHistogram);
Plot(UpVolAvg,"UpVolume Avg", colorBlue,styleHistogram);
Plot(DNV, "DownVolume", colorDarkRed,styleHistogram);
Plot(DownVolAvg, "DownVolume Avg", colorBrown,styleHistogram);
Plot(ADRatio,"Advance Decline Ratio",colorBlack,styleLine|styleOwnScale|styleThick);
Buy = C;
AddToComposite(UPV, "~UPV", "X" );
AddToComposite(DNV, "~DNV", "X" );
AddToComposite(TOTVol, "~TOTVol", "X" );

End Code -------------------------------------------

AD Ratio
Yes it did help very much, thank you Don. It looks much better and I
like the adjusted title. I think the source I was replicating
normalizes their data, and I'm inquiring as to their process.
Would you know how to plot this same style histogram for an up/down
volume ratio? I'm sure it just involves and extra step and I'm
working on getting the order of operations correct. Thank you very
much.
