Traders tend to negate their trading edge by trading during the 80% of the time when the market is not worth trading. If you think you are trading about 80% of the time, you need to evaluate your trading habits and make it more in-line with trading only 20% of the time and 80% of the time should be spent observing and keeping your hands in your pockets (not trading). If you look back over your trading account history from January 1st until now, ask yourself how many of the trades you lost money on where actually valid occurrences of your trading strategy (edge) versus random gambling-type trades that you entered out of emotion or impulse.
