I'm planning to use TT FIX for execution and live price data and IQFeed to download historical data. I've being using Pats for a while, and the way it worked was connecting IQFeed first and after Pats, but in this way live prices were taken from IQFeed as well (which is OK as Pats keeps crashing). Because TT FIX should be more stable, I will need just the historical data from IQFeed. Can you please advise on how to do that? Also, let's say TT disconnects, should I keep receiving live data from IQFeed (as backup)?
Thanks
Antonio
