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?
{'code': 'TR10', 'note': "Resulting (outcome bias) — the prompt grades process only and explicitly bans 'the outcome proves it' reasoning in either direction."}
