Assuming you have bars with the defined times. You are also doubling up on
the conditions, begvol = TimeNum() == 093500; is a 0 or 1, so you can never
have it correct in the next part cumvol = IIf(TimeNum() >= begvol
..............
Here is a short routine for what I think you are wanting, to sum the volume
from the first time to the second time
begvol = 93500;
endvol = 114500;
cumvol = IIf(TimeNum()<=endvol AND TimeNum()>=begvol, Sum( V,
BarsSince(TimeNum()==begvol)+1), 0);
Plot(Cumvol,"cumvol",colorRed,styleHistogram);
