Once two hours have passed in the trading day, you should have made at least two, or perhaps more, trades but enough to evaluate what you have done. Your emotions won't allow it, and a big losing day is likely to be the result. September 1995 is a true example for me of turning a bad family health situation into a bad financial situation. My father suffered a heart attack. He always was the pillar of strength to me, and to see him in intensive care was just too difficult.
Some people drown their problems with alcohol.
It turned out to be the worst trading month I had had in seven years. The person who knows you best is yourself. Listen to yourself. Keep in mind, as your trading day progresses, what money you have made or lost. It is much like knowing the score of a basketball game when you are the coach.
