      If I return to trading after performing these exercises and lose moneyon the next trade, I hang it up for the day. These days are not days that Iyet understand. I spend the rest of the day paper trading, and then analyzemy results after the closing bell. For me, this is one of the best ways tofigure out what it was that I didn't understand and what it was that costme money. If you can continuously learn from your mistakes without costingyourself too much of what I call "tuition money," you will, over time,become a better, more successful trader.
