Professional crypto market intelligence. Real-time prices, signals, and market scoring.
Output
A JSON object containing the base and quote assets, current Pearson correlation coefficient, correlation trend (e.g. stable/rising/falling), regime classification (e.g. strongly_positive), percentile rank within the lookback window, mean and standard deviation over the lookback, number of data points, and window/lookback durations in days.
Example use cases
Pairs trading correlation regime check
“I'm considering a pairs trade between SOL and AVAX — can you pull the rolling correlation stats for them over the last 30 days and tell me what regime we're in and whether the correlation is trending up or down?”
Portfolio hedging co-movement analysis
“I hold a big BTC position and I'm thinking about adding ETH as a partial hedge — what's the current correlation between them, what percentile is today's reading in over the past 60 days, and is the relationship stable or drifting?”
Mean reversion crypto pair screening
“I want to know if BTC and SOL are moving in lockstep right now or if they're diverging — what's the current Pearson correlation, where does it rank historically, and would you classify this as a good setup for mean reversion trading?”
