Traders who lose follow one of several typical patterns. Some repeatedly suffer individual large losses that wipe out earlier gains or greatly increase a small loss. Others experience brief periods during which their trading wheels fall off; they lose discipline and control and make a series of bad trades as a result.
The wise trader makes many small trades, remains involved and constantly maintains and sharpens his feel for the market. For all of his work, he hopes to receive some profit, even if it is small in dollar terms. In addition, continual participation allows him to sense and recognize the few real opportunities when they arise. These generate the large rewards that make the effort of trading truly worthwhile.
