Profit and loss provide an outcome, not an explanation. A winning position can contain a sizing error, while a losing one can follow a sound process and fail for an acceptable reason. Post-trade review becomes useful when it separates market analysis, execution, and management instead of judging everything through the final number.
Each fx trade should leave evidence that can improve a later decision. Five questions keep the review narrow enough to complete and detailed enough to reveal recurring strengths or weaknesses.
Did the Market Behave as the Thesis Expected
Compare the planned mechanism with the actual sequence. If the trade anticipated stronger rate expectations, did yields and related pairs confirm that shift? A profitable result caused by an unrelated headline should not be recorded as validation of the original idea.
Screenshots from entry and exit help prevent memory from rewriting the setup.
Was the Order Filled Under Normal Conditions
Record requested price, fill price, spread, and slippage. Compare them with the typical values for that pair and session. An entry during thin liquidity may explain a poor fill even when the platform functioned correctly.
Execution cost should be reviewed in cash and as a share of the planned reward.
Did Position Size Match the Written Risk
Recalculate monetary loss using the actual fill and stop. Conversion rates, partial fills, or a changed stop may have altered the amount. A small numerical deviation can become a persistent portfolio problem if it appears across many orders.
Risk compliance belongs in the review whether the position won or lost.
Which Decision Changed the Outcome Most
Suppose a long CAD/JPY position advances after entry, then retraces during an oil-price decline. Half is closed impulsively, and the remainder later reaches the original target. The thesis worked, but the unplanned reduction cut the gain more than entry slippage or financing did.
Reviewing the fx trade by decision isolates the costly intervention. It is more useful than describing the result as partly successful.
Is the Lesson Supported by a Series
One event can produce an unusual result. Tag the trade by setup, session, volatility, and management action, then compare it with similar cases. A rule should change only when a pattern appears or when one event exposes a clear structural flaw.
Review language should remain factual. “Bad trade” and “great entry” combine several judgments without identifying the behavior that produced them. Replace those labels with observations such as “entered before confirmation,” “filled above the maximum spread,” or “exited according to the time stop.” Specific wording makes patterns countable. It also limits hindsight because the review describes an action against a written rule rather than against knowledge of what price did afterward.
Opportunity cost can be recorded without inventing hypothetical profits. Note whether the position occupied margin during another valid signal, demanded unusual monitoring time, or remained open after its catalyst expired. The purpose is not to punish a trade for missing every alternative. It is to identify setups that consume resources for long periods without delivering the behavior they were designed to capture.
Within twenty-four hours of closing, answer the five questions and assign one category to the largest variance from plan. Do not alter the strategy immediately. Add the record to its comparable group and review the group at a scheduled sample size.
