After closing out a trade
Once you have closed your position, you should record everything about the trade. Write down where you wanted to enter the trade, what you expected out of the trade, and what you actually did get out of the trade. Make sure to include notes that will help you learn from the trade, reasoning what actually took place once you entered the trade. Explain why the trade was a winner or a loser. If you keep detailed records, you can learn from past trades and increase your chances of recognizing your strengths and weaknesses. Build on your strengths and stay away from trades you have demonstrated weakness in.
Another good thing to do is to keep a diary of your feelings. Learn which feelings go with the winning trades. Keeping such a diary will help you to become a more intuitive trader.
