#cci

Which markets are stretched to an overbought or oversold extreme on the Commodity Channel Index, computed live from Yahoo Finance (no key, nothing stored). The CCI measures how far price has run from its statistical average relative to normal volatility: above +100 a market is in a strong up-move (and, when it unwinds, overbought), below -100 a strong down-move (or oversold), and the swing through zero frames trend and reversal trades. For a cross-asset, cross-sector universe — equity indices and sectors, gold, oil, commodities, bonds and crypto — this computes each asset's 20-period CCI from its typical price (high+low+close over three) and tags it overbought, bullish, bearish or oversold, then ranks the whole board. The screener endpoint returns the overbought (>+100) and oversold (<-100) markets right now. The asset endpoint returns one market's CCI card. The universe endpoint lists what is covered. The cross-asset CCI / extension screener cut — distinct from the bring-your-own-candle oscillator API, the RSI screener (a different oscillator), the OBV/volume and Bollinger screeners. It finds the over-extended markets across every asset class at once.

Live OHLC momentum-oscillator analytics that traders run to spot overbought and oversold turns, computed on demand from the OHLC candles you pass in — no key, no cache, nothing stored. The stochastic endpoint returns the Stochastic Oscillator %K and %D, the classic measure of where the close sits inside its recent high-low range, with the %D signal line. The williams endpoint returns Williams %R, the same idea on a -100 to 0 scale. The cci endpoint returns the Commodity Channel Index, which flags how far the typical price has strayed from its average. Each result comes with an overbought or oversold reading so you can act on it immediately. These oscillators all need the full high, low and close — that makes them a different tool from closes-only indicator APIs like RSI and MACD, and from volatility and ATR tools: they measure momentum by where price sits within its range. Works for any market — forex, stocks, crypto or commodities — because you supply the candles. Computed locally and deterministically, so it is instant and private. Ideal for trading bots, screeners, signal dashboards and back-tests. Stochastic period defaults to 14 (smoothing 3); CCI to 20; Williams %R to 14. Live, nothing stored. 3 compute endpoints. For RSI, MACD or Bollinger Bands use a technical-indicators API.
