I'm having problems backfilling ES emini tick charts lately.
I collect less than 1 full session of data for my ES tick charts when I backfill.
For several weeks I have had the problem.
I do collect 5 sessions when I backfill for the NQ and ER2 but only 1 for the ES.
Is there something I'm missing?
I've tried clearing all data then backfilling. I've tried uninstalling the DTN/IQFeed client program and downloading it again from the link on QT's site. http://download.quotetracker.com/download/iqfeed_client_2_3_0_2.exe
Note: I've been using this set up for backfilling for years. Although it takes up to 5-8 minutes to collect the full 5 "days" of tick-by-tick ES data for my charts, it used to work very reliably.
(QT's maximum amount of saved unconsolidated data for tick charts is 5 sessions/days).
I do not have any problem displaying backfilled minute frequency ES charts. The chart will
display 10 days after a backfill (QT's max).
I'm using QT software for the ES emini (version 3.6.1a-2).
QT's Backfill site description is IQFeed US CUSTON - RealTime (Subscription) and I use
an .exe that has a checkbox for "Get Tick Backfill Data" .
