A journal is more useful when it explains the decision behind the result.
Profit and loss is an outcome. It does not always show what the system saw, whether a limit was active, who allowed the runtime to proceed or when it was paused. Those missing pieces make it difficult to improve an operating process responsibly.
Build a reviewable decision trace
For each meaningful event, record the market context considered, the risk plan applied, the runtime state, the operator action and the resulting event. That sequence can reveal process gaps without pretending that software can eliminate uncertainty.
Keep review separate from prediction
A decision trace is not a signal engine and it is not proof that a strategy will work. It is a record that helps the operator ask better questions about a workflow after the fact.
