If you are right 8 of 10 trades but giving back 80% of profits on the two losers , this tells me you have an inverted risk to reward setup, there are a lot of systems like this that look good on paper when you win 8 out of 10 but if you are giving back 80% on the two lost trades what happens if you have a bad month and you only win 6 of 10, if take 10 trades a month you will need 3 months of going 8 or 10 just to get back to even. this is not a good way to trade. You would be much better off with a system that wins less then 50% but makes twice as much on the winners as it does on losing trades
