The easiest journal to maintain is small enough to complete after every trade and structured enough to answer a real question later. Start with a minimum useful record, then add fields only when a review decision requires them.
Step 1: decide what the journal must help you answer
Do not begin by copying every column from someone else’s template. Begin with the review question. You might need to know whether a setup is profitable after fees, whether losses increase after rule violations, or whether actual risk differs from planned risk.
A field belongs in the journal only when it supports a decision, calculation, or review you expect to perform.
Step 2: record the minimum objective data
Objective fields create the base for calculations and comparisons. Use consistent formats and record the trade as soon as practical.
- Date and instrument
- Long or short direction
- Entry price, exit price, and quantity
- Open or closed status
- Planned risk and invalidation level
- Commissions, exchange charges, and relevant fees
Step 3: preserve decision context
Add a short setup label and one or two sentences explaining the trade. Record what you expected, what would prove the idea wrong, and why the position size was appropriate. After exit, note whether execution followed the plan.
Avoid writing a market essay after every trade. A concise, repeatable note is easier to compare than a page of unstructured emotion.
Step 4: use three review intervals
Different review intervals answer different questions. Keep each one narrow.
- After the trade: Was the plan followed? What changed?
- Weekly: Which behavior repeated? Which trade deserves a deeper review?
- Monthly: What does the larger sample say about setups, risk, costs, and consistency?
Step 5: change one thing at a time
A journal becomes useful when review changes behavior. Choose one testable adjustment and define how you will measure it. Changing position size, entry criteria, exit logic, and schedule simultaneously makes it difficult to know what caused a difference.
Keep the original record intact. Add the new rule and evaluate it on future examples rather than rewriting old trades to fit a new explanation.
