QT does not currently support Global Futures, but we do support PATS and are about to do add Global, so you would be able to use them as the datafeed. You could then add IQFeed for backfill which would cost $20 per month. QuoteTracker will automatically handle symbol conversion for most symbols between IQFeed and PATS.
If you want that particular setup, let me know and I can set it up for you before we release it to the public.
