In my second book, The PlayBook, I advocate archiving a favorite setup from each trading session. After each close, choose a best setup from the session that fits your trading style. Reverse engineer the variables of that trade. Archive this trade in a comprehensive format, perhaps like the SMB PlayBook. As traders we should build from our strengths, doing more or what works for us and doing it bigger, with more trading capital.
The first step is understanding what we do well. Study of our favorite setups after market hours and creating a system to do this is a best practice to improve performance.
