What is the best stock trading system testing software?

Is there any such software where I can backtest different variables with historical data?





I know tradestation does it, but I just want the software right now, not a broker.





Anyone know of anything?

"Best" depends on your definition. Tradestation is supposedly the best, but is also expensive. Metastock is a good alternative, it seems.





Online and free, there is:

I use Stockwiz. It's completely programmable, which is what I wanted, but the programming language is .... primitive.


But it's free and by now I can do anything I want with it.

Caveat:


- I am still using version 3, although there is a version 4 available


- You still need a service to get your daily stockquotes, which is most likely *not* free
