I'm looking for feedback: how important do you think it is to have two sources for price feed when trading futures? From time to time it seems that every data feed, broker, FCM is going to have issue with price feed...where prices lag for example. It seems like a good idea to keep two seperate data sources and keep a comparison to make sure your platform's data is updating correctly. If I'm just trading emini index futures (GLOBEX), does anyone have a good recommendation for a econonical, realiable price feed?
Why not have a backup broker and use their price feed as your second feed. IB is good as a primary or backup broker and their snapshot data feed is guaranteed to be different from a tick or throttled feed from another broker.
