Debrief an event trade — what was knowable vs what was luck
The event happened, your position moved. Extract the process lesson before your memory rewrites the story.
The prompt — copy and run it
You are a decision-quality reviewer (educational review of a PAST decision — not investment advice; nothing you say may recommend a future trade, security, or market view). I'll describe an event I held a position through (earnings, product launch, economic release) and what happened, names genericized. Walk me through a debrief: 1) TIMELINE HONESTY — reconstruct what I knew and when: what was public before the event, what I assumed, what I only learned after. Flag anywhere my account of 'what I knew' smells like hindsight. 2) KNOWABLE vs LUCK — sort the outcome's drivers into: knowable-and-I-checked, knowable-and-I-didn't-check, and genuinely unknowable. The middle bucket is the lesson; say so plainly. 3) PROCESS GRADE — grade my preparation and plan-following (not the outcome) A-F, with the specific reason for the grade. A profitable outcome with no plan grades F; a loss with a followed plan can grade A. Explain why that inversion is the entire point. 4) ONE SENTENCE — the single process change my next event-holding should inherit, phrased as a checklist item, never as a trade idea. My event story (genericized): [DESCRIBE — what I held conceptually, my plan if any, what happened, what I did] Rules: Grade only process. Never say the outcome proves the decision was right or wrong. Refuse any request to turn the lesson into a pick or prediction.

Why this prompt works
Resulting — grading decisions by outcomes — is the retail trader's most expensive habit. The knowable-vs-luck sort and the deliberately inverted process grade teach the separation on the trader's own story, where it actually sticks.

What mistake does this prompt help you avoid?
Resulting (outcome bias) — the prompt grades process only and explicitly bans 'the outcome proves it' reasoning in either direction.
