Crypto RSI & Oscillator Screener API

healthy 4,245 Subscribers

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.

RSI & Oscillator Screener (Multi-Asset) API

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.

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.

Stochastic & Oscillators API

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.
