In my experience, from 6 years of trading, I would say that one way to increase your profitability is to change your bet size. I don't know if you system only indicates either a buy or sell, or actually evaluates the quality of the trade. You have more winners than losers and if you can find a way to determine whether the trade is a 100 share or 1000 share trade, it could dramatically increase your net profitability. Any system that wins over 50% of the time can produce huge net results, but your winners need to be a larger average size than your losers. Hope this helps.
