TraderMatrix Free Gapper Scanner

Gapper Scanner (FREE preview) — 5-pillar low-float momentum gap scan (gap >=10%, price $1-$100, float <=100M, premarket volume >=50k; relative volume ranks the board and news is flagged; independent implementation, defaults differ from any educator's published criteria). Finds cheap small-cap stocks gapping up hard, flagging which have 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 cleared pillars first, then premarket relative volume descending. The result echoes 'session'. Want to force a session, tune the filters, pull up to 50 names, and unlock the full 51-tool connector (live options flow, GEX magnet levels, unusual activity, wheel screeners)?

Market Health history: the composite risk-score snapshots for the last 30 days (hourly, with flips7d = label changes in the last 7 days), a ~30-session derived line series per detector (percent vs moving average, ratios vs their MAs, N-day percent changes and spreads — never raw prices), and signalChanges: which scored detectors changed status since the previous trading day's last snapshot. Every line carries a unit string. The junk-credit-spread detector has no lines (its source series is third-party licensed) and economic-calendar events are not included. Self-caching (15 min). No parameters.

S&P 500 valuation verdict from a discounted-earnings (equity-risk-premium) model: verdict (Very cheap / Cheap / Fair value / Rich / Very rich), the equity risk premium the market currently implies (impliedErpPct, in percent — lower means richer), the zone on the ladder, how far the market sits above (+) or below (-) the Fair value band in percent, and five ERP bands each with its erpPct, its fair value relative to the Fair value band, and the market's percent distance from it. All values are percentages; index-point fair values, the index level and the earnings inputs are intentionally not published. A model, not a forecast. Self-caching (30 min). No parameters.

Takes no parameters.

US-government macro and liquidity series: Fed net liquidity (balance sheet minus Treasury General Account minus reverse repo, USD trillions, weekly, with the 4-week percent change), 10-year real yield, 10-year breakeven inflation, 5y5y forward inflation and the effective fed funds rate (percent, each with its prior value and date), the Treasury yield curve (1M-30Y) with the 10Y-2Y spread history (percentage points, negative = inverted), private nonresidential fixed investment (CAPEX, USD billions SAAR) and CFTC E-mini S&P 500 positioning by trader class (net contracts). Federal Reserve, NY Fed, Treasury, BEA, CFTC and Chicago Fed sources only; third-party-licensed credit-spread series are not included. Self-caching (6 h). No parameters.

Cross-asset regime read, derived values only: 60-session stock-bond and dollar-stock return correlations (-1..1), 20-session percent changes of the gold/S&P ratio, copper/gold ratio and WTI crude, the VIX/VIX3M ratio with a contango / backwardation word (above 1.0 = backwardation), and the MOVE/VIX ratio (rate vol vs equity vol). Raw index and commodity levels are not published; a leg that cannot be computed is null and named in unavailable[]. Self-caching (15 min). No parameters.

S&P 500 breadth, derived aggregates only: the percent of index members above their 20-, 50- and 200-day moving averages (0-100), a breadth zone for the 50- and 200-day readings (washed_out / weak / mixed / healthy / extended), advancers and decliners, new 52-week highs and lows with the net count, the member count, and a one-sentence read. The index level and its change are not published. stale is true when the live read failed and the last stored close is served. Self-caching. No parameters.
