I'm not a Tradestation user/customer but I'm under the impression that it's a very simple and user-friendly (albeit limited) platform to use. I'd be interested in hearing your opinions as to what makes it easy to use as it's not possible to demo without opening an account (which I won't). A couple of reasons I suspect are: - Datafeed included in the package, so you don't have to mess with downloading data - Extensive user forum with lots of examples of code
