i would seriously reconsider going with TS if youre not already committed. As a beginner platform it was really good, I basically used it as a sort of textbook, reading the EL for all the functions and strategies, but I've outgrown it's functionality in a big way lately, and reliability during big moves is really bad.
expect to get stuck in a position with a lock solid frozen TS and a crashed pc about once every two months or so, and expect to miss execution levels about once a week due to data latency if you're automating an intraday strategy.
this platform needs a few more years of hard core evolution before i could personally call it a professional grade product. Or .. it should be priced 1/3 to 1/2 lower than it currently is to be a decent value.
