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.

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.

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.

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.

555-timer (NE555) astable and monostable design as an API, computed locally and deterministically. The astable endpoint designs the classic oscillator: from the two timing resistors R1 and R2 and the capacitor it returns the output frequency f = 1/(ln2·(R1+2R2)·C), the high and low times (T_high = ln2·(R1+R2)·C, T_low = ln2·R2·C), the period and the duty cycle (R1+R2)/(R1+2R2), or solves the capacitor for a target frequency. The monostable endpoint designs the one-shot timer, T = 1.1·R·C — the pulse width of a single output pulse — and solves for whichever of the resistance, capacitance or pulse width you leave out. The design endpoint works backwards: from a target frequency, a chosen capacitor and a duty cycle it computes the resistor values R1 and R2 you need (a standard 555 needs a duty above 50 %). Capacitors may be entered in farads, microfarads, nanofarads or picofarads. Everything is computed locally and deterministically, so it is instant and private. Ideal for electronics-hobbyist and maker tools, oscillator, blinker, PWM and timing-circuit design, and electronics education. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 3 endpoints. This is 555-timer design; for Ohm's law, reactance and RC time constants use an Ohm's-law API.
