| get_premarket_gappers | Gapper Scanner (FREE preview) — the Warrior Trading "5 pillars" low-float momentum screen. Finds cheap small-cap stocks gapping up hard on high relative volume with a news catalyst. This free, no-key endpoint auto-picks the live session — pre-market gappers during 04:00-09:30 ET, after-hours gainers during 16:00-20:00 ET — and returns the top 10 on the default filters (up >=10% vs the session's reference close, price $1-$100, float <=100M shares, extended-hours volume >=50k). Each gapper: symbol, name, sector, last (extended-hours price), changePct (TRUE gap vs the reference close), atr, rvol (DERIVED premarket relative volume = premarketVolume / avgVolume, i.e. what fraction of a normal FULL day's volume has already traded — NOT TradingView's regular-session relative volume, which is meaningless before the bell), premarketVolume (extended-hours volume), avgVolume, float, rsi, and hasNews (a boolean catalyst flag — headline text and article links are not served here). Ranked by extended-hours volume. The result echoes 'session'. Want to force a session, tune the filters, pull up to 50 names, and unlock 24 more tools (live options flow, GEX magnet levels, unusual activity, wheel screeners)?
