[User Discussion] - VWAP-Differences on stocks

Hello,
i´m using SC for stock trading with IB´s realtime datafeed and noticed some differences on VWAP to IB and TOS.
My settings are:
InputData: Last
Base On Underlying Data: Yes
Time Period Type:: Days-24 Hour Period
Number of Days to Calculate: 1

When opening a chart before the regular market hour, i get VWAP values which don´t match to other platforms.
To resolve this problem i have to "Delete all Data on Download". When done this i get the same values as with IB´s TWS and TOS.
Is it possible to get the right values from the beginning (opening a new chart) ? I noticed some other users had also some issues with VWAP.

Thanks

This is exactly what I had when I had poor tick data. After downloading the history, everything was fine. "If you have the ability" to change from ib to sierra datafeed for your market, you will avoid further problems.
