A useful trading journal connects the decision you intended to make with the orders and fills that actually occurred. It should let you reconstruct losses as honestly as wins. It is not a guarantee of improvement, and no single metric replaces a review of strategy, costs and risk.

1. Identify the trade and account context

Record the instrument, contract or share class where relevant, account type and time zone. Use a private account label rather than exposing a full account number in shared notes. Distinguish simulated trades from live orders and prop-programme rewards from brokerage cash results.

Give the setup a definition and version, not just an attractive name. If the rules later change, keep the old version attached to the trades taken under it.

2. Preserve the plan before the outcome

Record intended entry conditions, quantity, exit policy and planned risk. Note any account restriction or event condition that mattered. A timestamped note is more useful than reconstructing a perfect rationale after a win.

Keep hypothetical ideas and missed trades in a separate log. Do not mix assumed fills with actual performance.

3. Reconcile orders, fills and costs

Capture entry and exit timestamps, quantities, partial fills and actual prices. Include commission and relevant financing or other charges. Reconcile totals with broker or provider records, documenting corrections rather than silently overwriting unexplained differences.

A planned $100 stop loss and an actual $250 loss require investigation. Possible explanations include slippage, a gap, the wrong quantity, a technical issue or a rule change. The difference alone does not prove poor discipline.

If the platform exports trades, check how it groups partial exits and multiple entries. Different grouping can change reported win rates without changing the account's cash result.

4. Record specific rule compliance

Name each relevant deviation: wrong account, quantity mismatch, entry criterion absent or stop moved without a defined reason. “Rules followed: no” can be a summary, but the underlying event should remain visible.

A profitable rule breach is still a breach. A losing trade that followed the rules is not automatically an execution error. Also record occasions when the rules were too vague to apply consistently.

5. Add context without inventing memory

A brief note about distraction, urgency or confidence can help reconstruct a decision. A numeric mood score is optional and subjective. It does not establish that an emotion caused the outcome.

If you complete the record later and cannot recall your reasoning, mark it unknown. Fill and order history can reconstruct transactions more reliably than feelings.

6. Review a question, not just a leaderboard

At a scheduled review, choose a specific question: Are duplicate orders recurring? Do actual costs differ from test assumptions? Were exits classified consistently?

Review the complete relevant sample, including contradictory cases. A profitable setup in a small sample is not an instruction to increase size. Check sample coverage, changing conditions and how many alternatives you tested before selecting a winner.

Record the proposed change, how it will be tested and what would cause you to reject it. Sometimes the right adjustment is to stop using an unsupported strategy.

Frequently asked questions

How long should an entry take? As long as needed to capture essential facts without interfering with position management. A multi-leg or partially filled trade may need more work than a simple round trip; there is no universal three-minute limit.

Should I include screenshots? They can preserve chart context, but are not a substitute for actual order records. Remove sensitive details before sharing and keep the timestamp and session settings clear.

What if I missed a trade in the journal? Reconstruct the transaction from records and mark any missing decision context. Include it in totals rather than omitting it because the narrative is incomplete.
