Profit and loss tells you what happened to the position. It does not tell you everything that happened in the decision. A useful journal preserves both, without allowing one to rewrite the other.

A winning trade might contain an order-entry mistake. A losing trade might follow the intended rules. Neither fact settles whether the strategy is sound. The point of a journal is to make those questions easier to investigate, rather than to award yourself a reassuring score.

Record the information you had

Before entry, save the setup, relevant event dates, the proposed exposure, and the condition that would invalidate the idea. Note what you do not know. Keep the original entry intact when you add later comments; hindsight is an enthusiastic editor.

If you use charts, label their date, timeframe, and the features you considered important. A screenshot with no explanation can become a Rorschach test when revisited after the outcome is known.

Separate decision quality from execution

Decision quality asks whether the proposed trade fit the method and circumstances. Execution asks whether the submitted orders and monitoring matched that proposal. Results ask what actually happened after costs. Give each a separate field.

Imagine a hypothetical trade that meets your research criteria but fills at a worse price than assumed. The journal should identify the fill problem rather than treating the whole event as either a triumph or a disaster. You may need better liquidity filters, more realistic testing, or different order instructions.

Make exceptions visible

Record changes to size, stops, targets, or time horizon, including the reason and when the change occurred. An adjustment supported by new evidence differs from a change made solely to avoid realizing a loss. You will not spot that distinction reliably if the record contains only the final story.

Include costs and any gap between modeled and realized risk. A planned exit level is not a guaranteed fill. For options, record contract details and relevant assignment or expiration events, not just the underlying stock’s chart.

Use the journal to answer one question

Choose a focused review question, such as whether fills are consistently worse in a particular setup or whether you repeatedly miss known event dates. Define the sample and look at unsuccessful cases too. A few memorable trades cannot establish a durable pattern.

End the review with a concrete research or operational task. Do not change five rules at once and then claim to know which one helped. Date the revision, preserve the earlier version, and state what evidence would justify keeping the change.

Use the Trade Planning Checklist as a companion for pre-entry notes. A journal is a record for investigation, not proof that trading is suitable or that a method will make money.
