What should a trading journal capture before you place a trade?
The short answer
Write down the setup you saw, the reason you decided to act, and the amount you decided before the session that you were willing to risk. Capture this before the trade, not after.
A journal entry made before the trade is more honest than one made after. Once the outcome is known, it is easy to rewrite the reason in your head to match the result. Recording the setup condition first, along with the invalidation point you chose, keeps the record tied to the decision rather than the outcome.
Keep the entry short. Note the instrument, the setup condition you identified, the invalidation point, and the size you chose relative to a small fraction of the account you had already decided on. The goal is a record you can read back later and understand exactly what you were thinking, not a story you tell yourself afterward.
How do you review journal entries after the session?
The short answer
Separate the review of your process from the review of the outcome. Ask whether you followed your written plan before you ask whether the trade worked.
Open the journal at a set time, away from any open positions. Read each entry and answer one question first: did this match the plan you wrote down in advance. That question has nothing to do with whether the trade made or lost. A trade can follow the plan and still lose. A trade can break the plan and still work out. Grading the decision separately from the result is what keeps the journal useful instead of just a scoreboard.
Once you have graded the decision, look at the outcome. Group entries by setup type rather than by day. Patterns show up across setups, not across single sessions. This is where consistency starts to matter more than any single result. Base hits build accounts, and a journal is how you can actually see whether you are hitting them.
How do you turn journal patterns into changes you actually make?
The short answer
Pick one pattern at a time, write a specific rule to address it, and test that single rule for a defined stretch of sessions before adding another change.
A journal that only collects entries without producing changes is not doing its job. Once a pattern appears, such as a setup condition you regularly enter too early or an invalidation point you often move after the fact, write one clear rule to address it. Keep the rule specific enough that you can check, after the fact, whether you followed it.
Change one variable at a time. If you adjust your entry timing and your position sizing in the same stretch, you will not know which change produced the difference in your review. Slow, single changes are easier to evaluate honestly, and the review itself is a decision you make about yourself, not about the market.
Take it with you
- Record the setup, reason, and risk decision before the trade, not after.
- Grade the decision against your written plan separately from the outcome.
- Review entries grouped by setup type to see patterns across sessions.
- Change one rule at a time and give it a defined review period.
- Base hits build accounts, and the journal is how you track them.
Questions traders ask
- How long should a journal entry take to write? Long enough to capture the setup, the reason, and the risk decision. It should not take so long that you skip it during busy sessions.
- Should the journal include feelings during the trade? A brief note on your state of mind can help you spot patterns tied to mindset, separate from the setup itself.
- What if a pattern does not improve after a rule change? Revisit the rule. Some patterns take more than one review cycle to address, and that is part of the process, not a sign to abandon the journal.
