Review a closed trade or a year of trades — process vs. outcome matrix, plan adherence, the biases that showed up, what the pre-trade skills said, and the one lesson for the journal; reads closed thesis-tracker files.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Trade Post-Mortem ## ⚠️ Data Verification — Do This Before Any Analysis Before running any analysis, always retrieve the latest market data for the ticker: 1. **Fetch current price** — use web search or ask the user for the live price, 52-week range, and market cap. Never assume a price from training data. 2. **Confirm key figures** — every fill (date, side, shares, price, fees) from the thesis file's decision log or the broker export; dividends received while held; the **total-return** closes of SPY and the chosen sector ETF on the exact entry and exit dates (adjusted for distributions); the stock's beta over the holding window; and the KPI values that were current on the day each decision was made. A post-mortem built on remembered fills or end-of-month benchmark prices grades the wrong trade. 3. **State your data source** — fill in the `Data & Sources` header (next section) so the origin, as-of date, retrieval path, and confidence of every figure are explicit at the top of the output. 4. **Flag stale data explicitly** — if live data is unavailable, display this warning before proceeding: …

How to install
mdr add yennanliu/investskill/trade-postmortem@sha256:a325cfdc692bd328The line at the top of this page pins the label git:20261024.1726f29, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
