My data feed is from Interactive broker. I expect my cumulative delta is calculated from the start of the trading day but not from the time i open the sierra chart. How to adjust the setting? Everything worked well before i switched the data feed to interactive broker from SC.

In study of cumulative delta bars, i set YES for rest at start of trading day already. Allow support for sierra chart data feed is enabled. Support downloading historical market depth data is Yes. Max historical market depth days to download is 5.
