Does anybody have experience with an API at either FfastTrade or VelocityFutures? Information seems to be completely hidden or nonexistent. How does the API compare with IB?
A member sent me a PM asking about API.
If you are not familiar with an API, look at the IB website. IB has a very extensive online description and manual. In short, it enables a user to interact via programming with, in this case IB, to place orders and get all kind of status feedback.
