RSI & Oscillator Screener (Multi-Asset) API

healthy 3,086 Subscribers

Which markets are overbought and which are oversold, ranked, computed live from Yahoo Finance (no key, nothing stored). The Relative Strength Index is the most-watched momentum oscillator: above 70 a market is overbought and stretched, below 30 oversold and ripe for a bounce, and the swing between them frames most mean-reversion trades. For a cross-asset, cross-sector universe — equity indices and sectors, gold, oil, commodities, bonds and crypto — this computes each asset's 14-day RSI (Wilder's method) and its 14-day Stochastic %K, tags it overbought / neutral / oversold, and ranks the whole board. The screener endpoint returns the markets that are overbought and oversold right now, sorted from hottest to coldest. The asset endpoint returns one market's oscillator card. The universe endpoint lists what is covered. The cross-asset RSI / oscillator screener cut — distinct from the crypto-only RSI screener, the bring-your-own-candle oscillator and technical-indicator APIs and the Bollinger and moving-average screeners. It finds the stretched markets across every asset class at once.

Crypto RSI & Oscillator Screener API

Which coins are overbought or oversold right now, computed live from Binance candles — no key, nothing stored. Momentum oscillators are the classic mean-reversion signals: a Relative Strength Index (RSI) above 70 says a coin is overbought and stretched, below 30 oversold and washed out, while the Stochastic oscillator times the turn within the recent range. The oscillators endpoint fetches a pair's candles and returns its Wilder RSI(14), the Stochastic %K and %D, and a plain signal (overbought, oversold or neutral) on a chosen timeframe. The screener endpoint scans a basket of coins and surfaces the ones that are currently overbought (possible pullback) and oversold (possible bounce), ranked by how stretched they are. The symbols endpoint lists tradable pairs. This is the coin-native oscillator / mean-reversion screener cut for crypto — it fetches the live data itself, distinct from the generic oscillator calculators (which you feed your own OHLC), the momentum trend-alignment, the Donchian breakout and the candlestick-pattern APIs in the catalogue. Pairs are Binance symbols (BTCUSDT) or a coin=BTC&quote=USDT form; interval is 1h/4h/1d/1w.

Technical Indicators API

Live technical-analysis indicators that traders and trading bots run on a price series, computed on demand from the closes you pass in — no key, nothing cached. Get Wilder's RSI; the MACD line, signal line and histogram; the upper, middle and lower Bollinger Bands with bandwidth and %B; and simple or exponential moving averages. Every value is computed live from your input and works for any market — forex, stocks, crypto or commodities. A technical-indicator engine, distinct from raw price feeds and from pivot/fibonacci level tools: it turns a series of prices into the momentum, trend and volatility indicators a strategy acts on.

FX Signals API

Live FX technical-analysis signals as an API, computed from European Central Bank daily reference rates. For any currency pair it builds the daily cross-rate series and returns the classic indicators traders watch — 20- and 50-day moving averages and their crossover (golden / death cross), a 14-day RSI (overbought / oversold) and momentum — rolled up into a simple bullish / neutral / bearish verdict. Get a pair's signal, its raw indicators with the recent closes, or scan a whole basket for the strongest setups. A ready-made signal layer for forex, trading and dashboard apps. Live, no key. Educational, not financial advice. Distinct from raw-rate, strength, volatility and correlation APIs.

CCI Screener (Multi-Asset) API

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.
