I know this question may have been presented before, but could not find it. Currently, I have realtime feed to Mytrack. I use their SDK. Works fine, but has been flaky lately (mytrack is not really helping resolve some user issues, and their seems to be uprising, but not much happening from Mytrack changes). I plan to live trade futures in the next 6 months, with account at IB. My system is automated - pattern recognition trading only. So, based on a model that trades tick by tick, can anyone tell me how "fast" the IB API calls (I use VC 6) are? I need to get data as fast as I request it (you know within a second). Is their API quotes / order entry a good speed? Anyone else using them for this type of methods? Thanks.
