RE: [amibroker] PlotOHLC & volume bars scaling problem

["Graham" <gkavanag@xxxxxxxxxxxxxx>]

How about this formula
Plot(V,"volume",IIf(C>O,colorBlue,IIf(C<O,colorRed,colorPaleBlue)),style
Histogram+styleThick);

Cheers,
Graham

Subject: [amibroker] PlotOHLC & volume bars scaling problem

Hello all,

I have a scaling problem when using PlotOHLC to plot thick volume bars.
If
you compare the 2 attached pics, you'll see that in image1, the volume
for
Jan22 is approx 6.8M and for Jan23 it is approx 3.1M.  The comparitive
size
of the bars looks right.

However, when I zoom in, the bars are identical in size.  See image2.

Is there anyway to get the volume bar scaling looking like the built-in
volume ?

Using StyleNoRescale still doesn't do the trick.

Here's the AFL I use:

// Color-coded thick volume bars
upbar = C > O;
downbar = C < O;
barcolor=IIf(downbar, colorRed, IIf(upbar,
colorBrightGreen,colorPaleBlue) );

Open=IIf(upbar, 0, V);
Close=IIf(upbar, V, 0);
High=Low=Open;

PlotOHLC(O,H,L,C,"Volume",barcolor,styleCandle);


Thanks,
HB
