Currency Correlation API
A live forex correlation analytic as an API, computed from European Central Bank daily reference rates. It measures how the world's currencies move together: each currency's daily appreciation is correlated against every other, so you can see which currencies move in lock-step (don't double up the same risk) and which move opposite (natural hedges). Get one currency's correlations to all others ranked, the coefficient for any pair, or a full correlation matrix for a basket. Risk and diversification input for forex, portfolio and trading apps. Live, no key. Distinct from currency-strength (direction) and FX-volatility (magnitude) — this is co-movement.
