Hi,
I did your exact system on the EUR/USD data I just pulled from Metatrader - I did only a break of 3 pips or more and a target of 5 pips (8 pips greater than the break). It goes from 24/09/2001 to 23/09/2009.
There are 1973 trades and 168 of them are losses. That's about a 91.5% win rate.
But the thing is I just don't buy your 10 pip stop loss working and the win rate remaining, that assumes it reaches it's extreme high or low after the break, we need 5 minute data to test this properly.
Also, with with 5 pips and spread of say, 2 points that's 3 pips for you and 2 for the broker, a commission of 40% on your winnings.
Actually your take profit is not triggered until the price has been hit and reached a further few pips - the spread,so you don'y exactly "see" the commission eaten away by your broker but ofc it is there.
I am preparing some data for you.
