Hi there,

If I wanted to look at volume totals for lets say today's 9:30 - 10:00 bar and add it to yesterday's 9:30 - 10:00 bar, and again add that volume total to the 9:30 - 10:00 bar of the day befor that, how do I designate a particular bar intervol and not the volume total for an entire day???

Thanks,

John
