Journal
Every trade you closed in the simulator, what it cost, and the score of the decision behind it. P&L is an outcome, a score is a decision — so they are shown apart, and it is the cross between them that says something about your method.
Next to every trade, the three journal questions: Why did you enter. How did you feel. What would have invalidated it. Answer briefly, on paper or in your head. What matters is before the next trade.
