Hello,

I have timezone set in Global Settings >> Data/Trade Service Settings to New York

I'm using on ES chart, VBP study with the following settings:

* Volume Graph period: Multiple Profiles from Start Time to End Time
* Use Different Start Time: Yes
* Start Time: 09:30:00
* End Time: 16:14:59

I noticed that values of VAH, VAL depend whether I'm using 1h or 15m chart.

For instance, for last Friday 12-Jun the values are as follows:

1h chart:

* VAH: 7444,00
* POC: 7434,25
* VAL: 7417,75

15m chart:

* VAH: 7443,25
* POC: 7434,25
* VAL: 7408,50


Why there are such differences depending on selected timeframe ?

Chartbook attached to this thread.


Cheers,

Look at the pictures you uploaded, the profiles don't contain the same data.
The 15-minute VBP starts at 09:30 and the 60-minute starts 10:00.

When you set the time in the VBP it includes the entire bar that contains the start time or end time, it does not divide the bars up.
