Fundamental Quality (XBRL) → Strategy → BacktestEnter a ticker. From SEC XBRL we compute three classic quality factors — Piotroski F-Score (0–9), Sloan accruals(earnings quality), and the asset-growth anomaly — point-in-time, filing-date keyed. An LLM picks which factor (or a composite) to gate on. Slow, annual signal; lookahead-free.
