Looks like a profitable system !!! Requires some hard discipline to trade it manually though.
It is most profitable during the trending markets with high volatility . ( London / NY are ideal) This one is based on London hours.  It uses volatility in it favor by entering and exiting quickly at reversing trends.
The good thing is that you could be out with some substantial  profit within an hour or so. 

1730 PIPS   -   in 4 months   

Some additional Suggestions:
1. Adjust stop loss to secure minimal profits.
2. Could also be used with GBP/JPY .
