Quick definition — The exit reason records which information or rule drove the decision to reduce or close a position. It is not the order sent, the execution price, or the resulting profit or loss.
A useful note reconstructs the step from the observed condition to the decision. It may identify, for example, setup invalidation, reaching an exit target, a time limit, a scheduled reduction, a risk limit, or an operational closure imposed by the broker. The category describes what happened; it does not automatically attribute discipline, fear, or competence.
The reason must be distinguished from three related elements: process adherence, meaning whether the choice followed the rules available at that time; execution, meaning the actual orders and fills; and the trade result, meaning the monetary outcome. Mixing these layers makes the journal difficult to verify.
Four layers not to confuse
Operational taxonomy
| Category | What it documents | Neutral example |
|---|---|---|
| Planned rule | A condition already present in the plan | Invalidation, target, time expiry, or scheduled reduction |
| Planned discretionary decision | A rule permits judgment within stated limits | Reducing exposure after a documented change in context |
| Operational or forced exit | Closure depends on infrastructure or external requirements | Broker liquidation, technical failure, expiry, or margin |
| Plan deviation | The choice has no applicable rule | Early closure without the planned trigger |
| Not assessable | The plan or contemporaneous evidence is missing | A reason reconstructed only after the fact |
“Planned” does not automatically mean well designed, and “discretionary” does not automatically mean wrong. Classification should support review rather than assign a moral grade.
Minimum recording card
- Copy the exit condition available before the trade, or state that none existed.
- Describe the observed trigger and decision time with verifiable facts.
- Record the action and order sent: full or partial close, quantity, and order type.
- Import actual fills, observable slippage, and costs; do not replace them with the desired price.
- Classify plan adherence as yes, no, or not assessable, citing the applicable rule.
- Record the outcome in a separate field and retain any quantity that remains open.
Verifiable example
The plan calls for a reduction if condition A ceases to hold. At 10:42, the datum defining A is no longer present, and an order to close the full quantity is sent. Two fills complete the order at different prices. The entry records:
- reason: planned invalidation of condition A;
- process: rule applied as written;
- execution: two fills, with actual average price and costs;
- outcome: net P&L, documented without using it to change the reason retroactively.
Review without outcome bias
Baron and Hershey experimentally showed that knowing a favorable or unfavorable outcome can alter evaluations of the quality of a decision made under uncertainty. Applied to a journal, this result supports comparing the choice with the information and rules available when the decision was made, while keeping subsequent events separate.
A compliant exit can produce a loss, and a deviation can produce a profit. A single case does not establish whether a rule is valid or invalid: changing it requires a documented series, stated criteria, and analysis of uncertainty.
Limitation — An exit reason does not determine which exit suits a person and cannot remove gaps, slippage, partial fills, or liquidations. It documents a process; it is not financial advice.
