Thanks to anyone who can help.
I've downloaded daily data for 1/1/2009-present from NT 7 (primary connection CQG, backup Kinetick) and most of the data shows OHLC for the RTH session. However, I have found that a small time period, from 2/21/2011-4/29/2011, reflects OHL prices of the globex sesion (4:30 PM previous day), rather than RTH.
What causes this behavior?
