David,
SelectedValue returns a Number.
So, xr0 and xs0 are Numbers.
When Abs() operates on a Number, it returns a Number.
Hence
bc = abs(xr0-xs0);
is a Number.
When you plot:
for( i = 0; i < BarCount; i++ ){
if(pR [i]) PlotText("" + bc[i] +" Bars", i, H [i] + txtH[i], 25);
if(pS [i]) PlotText("" + bc[i] +" Bars", i, L [i] - txtL[i], 42);
}
bc[i] is constant, as you see on the chart.
I'm not sure why bc[i] is an acceptable expression when bc is a
Number, but I imagine there is some reason for it.
Anyway, I think that's why you are not seeing the bar counts you are
aiming for.
