If anyone has experience with this.... when auto trading with GTP or FIX, can you log into the same account with Laser with and view your open positions, limit orders flying around, do some manual trading etc? I think the C++ API launches and controls a Laser window, so you can see all that stuff. Trying to decide the way forward ..... GTP, FIX, or C++ API.
Turns out with FIX and the API, yes you can. You need Genesis to setup a second user ID tied to your account like dafugginman said.
Haven't used Genesis, but getting an alternative ID will do. Can have potential problems, though. For example: Let's say you have a limit order that you placed via FIX. You alternate the FIX generated limit order on the broker's proprietary platform manually. A well thought out broker's system will send a message to your FIX engine that you have cancelled the order. Some brokers don't, they can have 2 different servers monitoring working/pending orders. Just watch out and ask questions to Genesis' IT.
