I am trying to backfill intraday data and the back fill fails. For some ETFs such as EEP and EEM, I get a message "BEST queries are not supported for this contract."
Other symbols such as ILF and IYE back fill with no apparent error but do not have data after 12/5. What could be causing these errors? Thanks, Barry I am using AB 4.90 and TWS build 877.5 with Java 1.6.0_02.
