Post From: VWAP - sessions

I have done the following steps in order to bring RTH VWAP onto my main chart by:

(1) Creating a separate intraday Chart (#5), showing only RTH, adding VWAP study
- Base On Underlying Data = Yes
- On a side note, my Global Settings > Data/Trade Service Settings > Intraday Stroage Time Unit = 1 Tick

(2) Adding the Study/Price Overlay study on my main Chart (#1), to reference Chart#5's VWAP study.

However, when I switch the timeframe on my underlying chart (#5) between 1min, 5min, 15min, 30min - the resulting VWAP line on the linked chart (#1) keeps changing.

What am I missing?
Could the fact that I'm on Sierra's free trial account affect my data used to calculate VWAP?
