I use Medved QuoteTracer with my IB data feed as a backup to my normal charting program. Sometimes, when the market is tanking, it it faster than my normal charting service, and from talking to other traders, it is faster than theirs also, no matter what charting program and data feed they are using.
However, it is NOT the official CME data feed, and as such can miss ticks which become significant in terms of support and resistance, so I do not rely on the IB data feed alone, and never will.
By the way, the time and sales logged in Quotetracker shows the footprints of the large orders - where they are buying the ask and selling the bid. I have learned it is a significant indicator, both in the eminis and the ACE bonds and notes.
Your other option with the IB data feed is Sierracharts, which has a monthly fee, as opposed to the optional one time registration fee for Quotetracker. I don't use it so I don't know how it logs T&S.
