How this service works
Rolling correlation between a crypto asset's daily returns and a stock/index ticker's (default SPY) over a lookback window (default 90 days, range 14-365) -- a cross-asset signal, e.g. is ETH still trading like a risk asset correlated with QQQ. Combines CoinGecko and Yahoo Finance daily closes. $0.01/call.
Output
A rolling correlation coefficient (typically between -1 and +1) between the specified crypto asset's daily returns and the chosen equity benchmark over the lookback window, computed from CoinGecko crypto price history and Yahoo Finance equity closes. Indicates whether the crypto is moving in sync with, opposite to, or independently of the benchmark.
Example use cases
Risk-on/risk-off regime detection
“Is Bitcoin still correlated with SPY over the last 90 days, or has it started to decouple from equities?”
Alt-season cross-asset signal
“Check the 30-day rolling correlation between SOL and QQQ — I want to know if Solana is trading like a high-beta tech asset right now.”
Portfolio diversification check
“Run the 180-day correlation between ETH and SPY for me — I'm trying to figure out if adding crypto actually diversifies my equity portfolio or if they move together.”
