Log every setup, psychology, outcome. No journal = no idea why you win/lose.
Without a journal, you remember the most painful losses and most exciting wins, but forget the ordinary trades. A journal turns emotional stories into data and shows where you actually make money.
Record date, instrument, direction, timeframe, entry reason, screenshot, stop, target, actual exit, result, emotional state and whether you followed the plan. Screenshots matter because they restore market structure.
Each week, ask three things: which setup has the best expectancy, which mistake is most expensive, and which time window triggers impulse. Do not review only profit and loss; review execution quality.
For every trade ask: why did I enter, where was I wrong, did I follow plan, and what changes next time? Thirty written trades teach more than thirty indicators.
