Post From: Extended VPOC line longer/shorter than expected

Hi,

I'm new to Sierra Chart and I've two questions:

1) I've added a 20 day VbP study on an continuous intraday RTH MES chart with the following settings:

Chart settings
--------------
Continuous Contract - Date-Rule Rollover backadjusted
Chart Data Type - Intraday Chart only
Days to load for Intraday Chart Data Type - 100
Session Start Time - 9:30:00
Session Stop Time - 16:59:59
Use Evening Session - no

VbP
---
Ticks per Volume Bar - 1
Volume Graph Time period Type - One Period at End of Fixed Time Length - Auto-Skip Empty Days
Time Period Type for Fixed Time - Days
Time Period Length for Fixed Time - 20
Extend Point Of Control - End of Period

When I look now at the extended (End of Period) VPOC line the line covers 21 days instead of the 20 days I would have expected(1-2 to 1-31). Why?

And when I change the Bar Period from 15min to 1 Day the VPOC line covers suddenly only 15 days and the 20 day VPOC value jumps from 6065 to 6127.50. Why?

2)

On every of my intraday charts Days to load for Intraday Chart Data Type is set to 10. When I change this value to 100 and I click OK Sierra loads 100 days of data. No problem. But the next time I open the chart settings the value switched back from 100 to 10. The problem is when I'm changing any other value in the chart settings and I forget to set the number of days it loads 10 days again instead of the number of days I've originally set. Is that normal? Why does it not save the number of days to load?

Thanks for any help!
