Winning Percentage
The reality of trading is that most successful traders take small losses or gains on the majority of their trades, while their real money comes from a few trades that turn out to be big winners. By essentially “scratching” most of their trades they protect their capital, making it possible to wait patiently for the small handful of positions that turn into large gains.
