Cross-Asset Correlation Matrix API

healthy 4,455 Subscribers

How the major asset classes move together — a live correlation matrix across stocks, bonds, gold, oil, crypto and the dollar (no key, nothing stored). Correlation is the single most important input to diversification and risk: two assets with a correlation near 1 are effectively the same bet, while a low or negative correlation is genuine diversification. Where a crypto-correlation API stays inside crypto and an FX-correlation API stays inside currencies, this spans the whole multi-asset book at once — US and international equities, Treasuries and credit, gold, silver, oil and broad commodities, Bitcoin and Ether, the dollar and real estate — so an allocator can see in one call whether bonds are still hedging stocks, whether gold is decoupled and whether crypto is trading as a risk asset. The matrix endpoint returns the full pairwise return-correlation matrix over a chosen window, with the most- and least-correlated pairs. The asset endpoint returns one asset's correlation to every other, ranked, so you see its best diversifiers at a glance. The assets endpoint lists what is covered. The cross-asset / multi-asset correlation surface — distinct from the crypto-only correlation API, the FX-only currency-correlation API and the bring-your-own-series CAPM, risk-metrics and portfolio-optimiser calculators.

Multi-Timeframe Momentum & Alignment (Multi-Asset) API

Whether each market is trending the same way across every timeframe, computed live from Yahoo Finance (no key, nothing stored). A single week's move is noise; what trend traders want is alignment — when the 1-week, 1-month, 3-month, 6-month and 1-year returns all point the same direction, that is a strong, coherent trend, and when they disagree the move is choppy or turning. For a cross-asset, cross-sector universe — equity indices and sectors, gold, oil, commodities, bonds and crypto — this measures each asset's return over those five horizons, the up/down direction of each, and an alignment score from -5 (every timeframe down) to +5 (every timeframe up), with a coherence label. The screener endpoint returns the fully aligned uptrends and downtrends across the board, ranked by alignment. The asset endpoint returns one market's multi-timeframe momentum card. The universe endpoint lists what is covered. The cross-asset multi-timeframe momentum / alignment cut — distinct from the crypto-only multi-timeframe API, the commodity-momentum ranking and the relative-strength APIs. It finds the coherent trends across every asset class at once.

ADX & Trend-Strength Screener (Multi-Asset) API

Which markets are strongly trending and which are stuck going nowhere, computed live from Yahoo Finance (no key, nothing stored). The Average Directional Index is the definitive measure of trend STRENGTH (not direction): above 25 a market has a real trend worth riding, below 20 it is choppy and range-bound where trend systems get whipsawed. The companion +DI and -DI lines give the direction — +DI over -DI is an uptrend, the reverse a downtrend. For a cross-asset, cross-sector universe — equity indices and sectors, gold, oil, commodities, bonds and crypto — this computes each asset's 14-day ADX, +DI and -DI (Wilder's method), and classifies it as a strong uptrend, strong downtrend, developing trend or ranging. The screener endpoint returns the strong uptrends and downtrends across the board, ranked by ADX, plus the ranging list. The asset endpoint returns one market's directional-movement card. The universe endpoint lists what is covered. The cross-asset ADX / trend-strength screener cut — distinct from the bring-your-own-candle trend-indicator API and the moving-average, RSI, MACD, Bollinger and Donchian screeners. It separates the trending markets from the chop across every asset class at once.

Candlestick Pattern Screener (Multi-Asset) API

Which markets just printed a reversal or continuation candlestick pattern on their latest daily candle, computed live from Yahoo Finance (no key, nothing stored). Candlestick patterns are the oldest price-action signals there are: a hammer at a low hints a bounce, a shooting star at a high a turn, an engulfing candle a momentum shift. For a cross-asset, cross-sector universe — equity indices and sectors, gold, oil, commodities, bonds and crypto — this reads each asset's most recent candles and detects the classic single- and two-candle patterns (doji, hammer, inverted hammer, shooting star, hanging man, bullish/bearish engulfing, bullish/bearish harami, marubozu), tagging each bullish, bearish or neutral. The screener endpoint returns every market flashing a pattern right now, split into bullish and bearish signals. The asset endpoint returns one market's latest candle with any pattern detected on it. The patterns endpoint lists what is recognised. The cross-asset candlestick-pattern screener cut — distinct from the crypto-only pattern detector and the bring-your-own-candle pattern API. It scans the whole market for price-action signals at once.

Donchian Channel Breakout Screener (Multi-Asset) API

Which markets are breaking out of their recent trading range, computed live from Yahoo Finance (no key, nothing stored). The Donchian channel — the highest high and lowest low of the last N days — is the breakout system the legendary Turtle traders rode: a close above the 20-day high is a classic long entry, below the 20-day low a short, and the 55-day channel is the slower, higher-conviction version. For a cross-asset, cross-sector universe — equity indices and sectors, gold, oil, commodities, bonds and crypto — this computes each asset's 20-day and 55-day Donchian channels (upper, lower and midline), where price sits inside the 20-day channel, and flags fresh breakouts above the high or below the low. The screener endpoint returns the upside and downside breakouts across the board plus the channel-position ranking. The asset endpoint returns one market's Donchian card. The universe endpoint lists what is covered. The cross-asset Donchian / channel-breakout (Turtle) screener cut — distinct from the crypto-only Donchian screener, the 52-week-range screener (a much longer window), the Bollinger-Bands screener and the bring-your-own-candle indicator APIs. It catches the range breakouts across every asset class at once.
