As far as I see its best to make sure any EA in the marketplace is proven by using your own money on a live account before actually purchasing a paid for product. This EA is a free version of the EA Power Bar Scalper. The only difference is lot size has been fixed to 0.01 lots.  

The concept is simple but effective. It only trades when the previous bar is above average size of the previous 19 bars. Usually, with large powerful bars like this it often means there will be a momentum in the markets in direction of power bar. Its this momentum which is the captured using some basic trade management methods.
