Hey all fun little tool to let you practice trading or test a strategy, its totally free and best part, I did a video so you don't have to read thru 12 pages of directions. All kidding aside great tool for new traders or traders looking to manually test a strategy.
It lets you replay historical market data, and you can speed up and slow down the market as it runs. http://www.mt4i.com/appstore/app.aspx?id=22&sort=popularity
