CQG routes trades through what they call Futures Commission Merchants (FCM) Partners. For a list of FCM partners, checkout Trade with FCM Partners. This is essentially what TT does. I have used both products and I can honestly say that CQG is a far superior product. It is more integrated, robust and user friendly. TT is a product joined togather by sub-applications. It was created for market makers and hence the focus of the entire product is different. Of late, they have tried to make amends but still it is the same product. They are well known for patenting their Static DOM product and then later going after other vendors including CQG for copyright infringement. CQG got around the problem by making cosmetic changes to their DOM and it works well. BTW, CQG charting product is very good and it also comes with a backtesting and trading tool which is great for technical traders. There is no backtesting tool as I know it in TT when I last used it in July of this year. TT's charting is dependant on FCM's providing a server to hold data for the charting. CQG provides all data from their data store independent of FCMs. It's a big difference.
