Being Wrong 20 Times but Being Okay

In Jack Schwager's famous book "Market Wizards" (1989), day trader and trend follower Larry Hite offers this practical advice: "Never risk more than 1% of total equity on any trade. By only risking 1%, I am indifferent to any individual trade." This is a very good approach. A trader can be wrong 20 times in a row and still have 80% of his or her equity left.
