Methodology
How a signal is made — and proven.
No black box, no cherry-picking. The pipeline is deterministic, the claims are logged, and the outcomes are graded in public.
Ingest
Live market feeds stream price, volume, options, financials, filings, and news for every US stock and ETF — every market day.
Compute
50 quantitative models score five factors — technical, momentum, fundamental, options, microstructure — into one composite per ticker.
Verify
Every issued signal is logged with its claimed win probability, then resolved against live prices. Calibration is graded and published — walk-forward, never re-scored after the fact.
Deliver
Scores, charts, alerts, and AI research update through the day — on the dashboard, Telegram, API/MCP, and QL Intelligence.
Why you can trust the numbers
Signals are timestamped at issuance — targets, stops, and scores are immutable once logged.
Outcomes resolve against live market prices, not self-reported fills.
The full track record — wins and losses — is public at /proof.
Machine-learning weights re-tune on measured accuracy, not narratives.
