Mara’s broken entry rules. September risks repeating every August loss.

A trading journal should record the decision before the order, including the entry rule, invalidation level, size, and reason to skip. Recording profit and loss afterward can hide the repeated choice that created the loss.

At 6:18 p.m. on a Friday, Mara sat at her kitchen table in Lisbon with a cold mug beside her laptop and August trades filtered on the screen. She had planned to check a few exits before dinner. Instead, she saw the same note missing from every losing entry: the condition that had to be true before she could buy.

Her August result was down, but the dollar amount was not the discovery. Each loss had started with a broken entry rule. One trade chased a move after price had already run. Another entered before the planned confirmation. A third had a valid idea, then exceeded the size Mara had written down because the chart looked “too clean” to miss.

The uncomfortable possibility was clear. If she kept reviewing only outcomes, September could produce the same pattern with different tickers. A few profitable rule breaks could make it even harder to spot.

This is an illustrative composite, not a customer result or financial advice.

The loss was visible, but the decision was missing

A conventional journal can make a losing trade look complete: symbol, entry, exit, gain or loss, and a screenshot. That record answers what happened to the position. It often says little about whether the trade met the trader’s own conditions.

Mara had written “late entry” beside several August losses. It sounded like a lesson, but it was too broad to change her next decision. Late compared with what? Which rule had been overridden? What evidence had she accepted instead?

Thin August liquidity made that vagueness more dangerous. A chart can move sharply on limited activity, widening the gap between a planned entry and the price available when a trader reacts. The issue may not be the trade idea. It may be the moment a trader abandons the rule designed to keep a fast move from becoming an impulse order.

Her review needed a different unit of analysis. Each row had to begin before execution.

Build each journal entry around the approval decision

Mara replaced her outcome-first template with a pre-order decision record. Before placing an order, she wrote four short fields:

• The entry condition: the observable event required before entry.
• The invalidation point: what would prove the idea wrong.
• The planned position size: based on the amount she was prepared to risk.
• The reason to pass: the condition that would make the trade unacceptable, even if price kept moving.

For one setup, “bullish momentum” became: “Enter only after price holds above the prior level for the defined confirmation period.” “Small size” became a stated number of units. “I will exit if it feels wrong” became a price level that invalidated the original thesis.

That shift creates an approval gate between seeing a setup and sending an order. A queued signal or a manual order can still be rejected when the evidence does not match the plan. The trader keeps the final decision, but the decision has a standard to answer to.

This is the same discipline behind Daniel’s blank risk section: if the risk case is absent before entry, the trade has not earned approval.

Review rule adherence separately from profit and loss

On the next Friday, Mara reviewed her decisions in two columns. The first asked whether each trade followed the entry rule. The second showed the outcome.

That separation mattered. One rule-following trade lost after entry, then closed at its planned invalidation. It belonged in the “followed plan” column. One rule-breaking trade made money after Mara entered late. It belonged in the “broke plan” column.

Without this split, the profitable mistake can become the most persuasive one. It teaches the trader that breaking a rule worked. A journal built around the pre-order decision makes the mistake visible even when the market rewards it.

Use plain labels that make review fast:

• Approved: every required entry condition was present.
• Rejected: a required condition was absent, or the trade exceeded the risk limit.
• Modified: the original plan changed, with the reason recorded before execution.
• Rule break: an order was placed despite a known missing condition.

A modified trade deserves scrutiny. A change made before the order, with a defined reason and size, gives the trader something to evaluate. A change made after urgency takes over usually belongs in the rule-break column.

Turn the next review into a narrower test

Mara did not promise herself a perfect September. She chose one measurable constraint: no entry unless the journal contained a written entry condition and invalidation point first.

On Monday morning, a familiar setup moved before her confirmation condition appeared. Her old journal would have captured the entry price if she chased it. The new journal had an empty approval field and a clear reason to pass. She watched the move continue without her.

That can feel like a missed opportunity. It is also a completed decision.

At the following Friday review, Mara would have a cleaner question than “Did I make money this week?” She could ask: “How many orders met the rule I wrote before the market tested my patience?” That answer is where trading discipline begins.
