I'm just starting out creating my own trading system ( mechanical /descritionary ) . I try to keep it simple and know what i'm looking for. I gained this ability by scanning 100 - 300 charts per day mannually from a watchlist. I did this for about a year, and it's finally taking a toll on my eyes. So, my question is what's a good trading platform to use for someone who probably want to create his own mechanical system and paper trade for about 3 months or so? I currently using schwab streetsmart pro and stockcharts (both are very limited). thanks for your advices!
