Quote from j_medved:
slapshot, Yes, with IB data, if you are not running the software gathering data for a period of time, your charts will have a gap. However, you can backfill using a different source - QT allows you to select a backfill source independent of the primary quote source. That was why I mentioned that you can backfill IB futures symbols using IQFeed now (you could always do that with stocks)
SDK - Software Development Kit - What QuoteTracker and other 3rd party software companies use to access myTrack data and trading. The fee is required by myTrack (monthly)
So, what I'm gathering so far is that for the $23.00 the IQ feed is the way to go for simple E-mini trading with backfill.
I can use my existing IB for backup.
Please correct me if this is not the case.
Thanks for replies.
Paul
