does anyone use qst (quick screen trading) as a platform?
It is a white label software offered by some brokers. I checked a demo and it seems ok. Has anyone some any experience with it (reliability, speed e.a.)?
Yes, it looks ok for my requirements. I am not an ultrafast scalper, so it is fine as an order entry tool, if it is stable and fast enough. They use TT for data and order routing as far as I know.
