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.

Ulcer Index API

Ranks a cross-asset universe by how painful each market's drawdowns have been, and how much return it paid for that pain, computed live from Yahoo Finance daily closes — no key, nothing stored. Volatility treats an up-move and a down-move as equally risky, but investors only lose sleep over the downside: the depth of the fall from the last high and how long it drags on before recovering. The Ulcer Index (Peter Martin) captures exactly that — the root-mean-square of every day's percentage drawdown from the running peak, so a deep, long drawdown is penalised far more than a brief dip and a market that keeps making new highs scores near zero. From it comes the Martin ratio (the Ulcer Performance Index) — annualised excess return divided by the Ulcer Index — the return earned per unit of drawdown pain, a downside-only cousin of the Sharpe ratio. The asset endpoint returns one instrument's full pain profile: Ulcer Index, maximum, average and current drawdown, longest time underwater, the Martin ratio and the pain ratio. The screener endpoint ranks the 21-instrument universe (equities, sectors, commodities, bonds, crypto; filterable by class) by Martin ratio (best pain-adjusted return) or by Ulcer Index (smoothest ride). This is the drawdown-pain / Ulcer-Index cut — distinct from a current-drawdown monitor (a point-in-time snapshot of how far below peak each market is), the Sharpe/Sortino/Calmar screener (Calmar uses only the single worst drawdown) and the price APIs. It scores the whole shape of the pain, not one point of it.

Beta Screener API

Ranks a cross-asset universe by beta to a benchmark, so you can see at a glance which markets amplify the benchmark's moves and which dampen or hedge them, computed live from Yahoo Finance daily closes — no key, nothing stored. Beta is the single number that says how much an asset moves for each 1% the market moves: a beta of 1.3 rises ~1.3% when the benchmark rises 1% (and falls harder when it drops), a beta near 0 is decoupled, a negative beta moves against the market (a hedge). The screener endpoint ranks the 21-instrument universe (equities, sectors, commodities, bonds, crypto; filterable by class) by beta to a chosen benchmark (the S&P 500 by default), each with its correlation and R-squared so you know how reliable the beta is. The asset endpoint returns one instrument's full beta profile against the benchmark. The dispersion endpoint returns the spread of betas across the universe — the high-beta-minus-low-beta gap, the mean beta and the share of risk-on names — a read on how much the market is rewarding risk-taking right now. This is the systematic-risk / market-sensitivity ranking cut — distinct from a bring-your-own-series CAPM/beta calculator, the total-risk Sharpe/Sortino screener, the correlation matrix and the price APIs. It ranks live assets by how much market risk they carry.

Risk-Adjusted Return Screener API

Ranks a cross-asset universe by how much return each asset delivers per unit of risk, live from Yahoo Finance daily closes — no key, nothing stored. A raw return tells you nothing about how much risk you took to earn it: two assets up 12% are not equal if one rode a calm trend and the other whipsawed through deep drawdowns. This screener turns each asset's price history into the three risk-adjusted ratios allocators actually rank on — the Sharpe ratio (excess return per unit of total volatility), the Sortino ratio (excess return per unit of downside volatility only), and the Calmar ratio (annualised return per unit of worst peak-to-trough drawdown) — and sorts the whole universe (21 instruments across equities, sectors, commodities, bonds and crypto) so you can see in one call which markets pay the most for the risk you bear. The screener endpoint ranks the universe (filterable by asset class) by the metric you choose; the asset endpoint returns one instrument's full risk-adjusted profile with plain-language reads. This is the risk-adjusted-return / reward-per-risk ranking cut — distinct from a bring-your-own-series Markowitz optimiser, the CAPM/beta calculator, the momentum and the price APIs. It ranks live assets by efficiency, not raw performance.

Keltner Channels Screener (Multi-Asset) API

Which markets are breaking out of their volatility-adjusted trend channel, computed live from Yahoo Finance (no key, nothing stored). Keltner Channels wrap a 20-day exponential average in bands set at two Average-True-Ranges above and below it — and unlike Bollinger Bands, whose width is statistical standard deviation, Keltner's width is the market's actual trading range. A close above the upper Keltner band is a trend-following breakout (riding strength), below the lower a breakdown, and price hugging a band signals a powerful, persistent trend. For a cross-asset, cross-sector universe — equity indices and sectors, gold, oil, commodities, bonds and crypto — this computes each asset's Keltner upper, middle and lower bands, where price sits inside the channel, and flags fresh breakouts. The screener endpoint returns the upside and downside Keltner breakouts across the board. The asset endpoint returns one market's Keltner card. The universe endpoint lists what is covered. The cross-asset Keltner-channel / volatility-trend screener cut — distinct from the Bollinger-Bands screener (standard-deviation width, mean-reversion), the bring-your-own-candle ATR API and the other indicator screeners.
