"Most traders think there are two types of trades: winning and losing. Actually, there are four types of trades: winning trades and losing plus good trades and bad trades. Don't confuse the concepts of winning and losing trades with good and bad trades. A good trade can lose money and a bad trade can make money. A good trade follows a process that will be profitable (at an acceptable risk) if repeated multiple times, although it can lose money on any individual trade." - Jack Schwager
