[amibroker] Re: Mirroring the Chart

["rhoemke" <robert@xxxxxxxxx>]

It seems that there is at least a problem with Barcount and BarIndex().
As i understand, Barcount is just a number, showing the total number
of bars in the chart (starts counting at 0), and BarIndex() shows the
actual number of the single bar.
But this code shows  different figures even for BarCount at selected
bar and i don't know why.
Anybody who can help?

SBI = SelectedValue(BarIndex()); 
"Selected BarIndex = "+WriteVal(SBI);
"BarCount = "+WriteVal(BarCount);


Regards
Robert
