I have used tradestation twice over the past 10 years. Good charting, not an easy language to master, and the results are no "holy grail" if that is what you are expecting.
Tradestationis no cure all. You must decide what information you need to make decisions, do your research and not rely on advertised claims like tradestation.
If it was so great, everyone would use it, we would all make the same decisions and then it would become ineffective.
