I played with a demo account of ForexTester some time ago, it is a good back testing solution.
Forextester allows you to replay market conditions/price actions months from the past and see how you or your trading strategy would do. For example, if you want to go back to last January and enter a few trades you can do that.
The software will actually simulated what the market conditions were like at that time, allowing you to pause and rewind the charts or even enter trades so you can get a feel for how the market moves. The tool is really geared toward helping traders practice their trading skills.
Money management is king, a great strategy is queen.
