On The Importance Of Creating Trading Rules

“The typical trader will do most
anything to avoid creating definition and rules because he does not want to take
responsibility for the results of his trading. If he knows exactly what he is
going to do and under what conditions, then he would have something by which to
measure his performance, thus making himself accountable to himself. This is
exactly what most traders don’t want to do, preferring instead to keep their
relationship with the market somewhat mysterious.”
