A journal should explain the decision, not just the result
If your journal only records entry, exit, and profit, it tells you what happened but not why. The real value comes from comparing the plan you intended to follow with the decisions you actually made.
Over time, that creates a record of behavior. You can see whether losses come from weak setups, poor execution, oversized risk, or repeated rule-breaking.
Record the setup before the trade
Write the thesis before you know the outcome. Capture the market, timeframe, trend context, entry trigger, invalidation level, position size, and target logic. A screenshot can be useful if it shows exactly what you saw at the time.
Pre-trade notes prevent hindsight from rewriting the story later.
- Market and timeframe.
- Reason for entry.
- Invalidation and stop.
- Position size and planned account risk.
- Expected holding period.
- Market condition: trending, ranging, volatile, or unclear.
Record execution separately from strategy
A strategy can be valid while execution is poor. Note whether you entered late, moved the stop, closed too early, added to a losing trade, or ignored the original setup. Those are execution errors, not necessarily strategy errors.
Separating the two helps you avoid changing a strategy when the real issue is discipline.
Review patterns in groups of trades
One trade is noisy. A group of trades can reveal a pattern. Review by setup type, timeframe, market condition, and rule adherence. You may discover that the same setup behaves differently in a range than in a strong trend.
Also track the quality of the process. A simple “followed plan: yes/no” field can be more useful than another indicator.
Turn review into one small change
A journal is not useful if every review produces ten new rules. Pick the clearest recurring problem and change one part of the process. Then watch the next sample of trades.
The goal is steady improvement, not constant reinvention.
