Time for another classic trading book excerpt.  The subject is similar to the one in yesterday’s post. It is about limiting losses and ultimately becoming a better trader if you are willing to embark on that never ending journey to better understand yourself. James L.

Harper’s human behavior material gives us insights into the handicapping prejudices that ruin our stock market theories and sound resolutions. Especially in our computer oriented age does the average investor seem incapable of calm reasoning , with the result that he often does precisely the opposite of what he had intended doing.
