# QM Screener

> A daily momentum stock screener. Six published trend and momentum methodologies — Qullamaggie, Minervini trend template, VCP, gappers, and two Mike Webster proxies — run against the full US equity universe after every trading-day close.

## When to use this

**Use it when:**

- the user asks which US stocks are breaking out, consolidating, or setting up today, and wants a named methodology behind the answer rather than an opinion;
- the user names one of the six methodologies — Qullamaggie, Minervini trend template, VCP, gappers, Webster swing, Webster recession — and wants today's passing tickers;
- the user wants the actual filter values (RS percentile, ADR%, dollar volume, distance from the 50-day SMA) that a ticker passed or missed on;
- the user wants a momentum watchlist they can paste into TradingView.

**Do not use it when:**

- the user wants a trade recommendation, a position size, or a price target — this is a screen, not advice, and it returns none of those;
- the user wants intraday or real-time quotes — results are end-of-day and refresh once per trading day after the US close;
- the user wants fundamentals, filings, or news — none are covered;
- the market in question is not US equities.

The REST API is pinnable at `/api/v1/`; the unversioned `/api/` form
is a permanent alias. Every response carries an `API-Version` header, and a
breaking change would take a new prefix rather than change this one.

## Subscriber-only

Full result sets — every passing ticker, the near-miss list, the mean-reversion
list, and each ticker's filter values — need an active subscription. $5.00
per month or $42.00 per year, both after a 7-day free trial. See
