Hello, I am currently looking for new ways to Transfer trades to my clearer. I have basically the choice between TT X_Trader and CQG. I am currently testing X_Trader pro API (I have to use the X_Trader Pro API and NOT the TTFIX API). I have the Setup running since a couple of days on a SIM test Server and I found that the "Guardian" Application has restarted and the Connection between my proprietary application and the Exchange was lost. TT Looks very innovativ to me but one of the main reasons I want to Change to X_Trader is that I Need a very reliable Setup and I go into chaos if the API does not work correct. I have allready spent to much time in my life on Projects which have not worked in the end and I like to aks the following question to the experience Traders: Question: From your POV what API is reliable, do you have good experience with the X_Trader Pro API or does CQG provides better Connection?
