Using your emotions as trading information

Also, I particularly like Dr. Menaker’s work on using your emotions as trading information. When I get pissed about slippage in a stock I use that trading information to move away from the stock. When I am too comfortable in my positions, I know I need to focus on being bigger. When I sense I am not in the right mindset before the open, I play partner for the day and lock myself in my office.
