Low Risk High Reward Strategy

So I have this new trading strategy which is low risk but high reward. I am talking about 300x reward versus risk. So I run this for 1$ starting capital, and it back-tested to 313$ in 2 years (see the results).

Number Wins = 24
Number Loss = 34
Win Average = 22.8
Loss Average = 6.9

Expectancy Ratio = (No.Wins X Win Ave.) - (No. Loss X Loss Ave) = (24 X 22.8) - (34 X 6.9) = 312 (no kidding)
Expectancy Ratio = 312
