Correlys asks whether your market relationship survives its window

Field notes

The proposed workflow separates four failure modes that are often compressed into a single correlation statistic: non-stationarity, regime dependence, uncorrected hypothesis searches, and out-of-sample breakdown. Correlys says the underlying series are public and free, while its paid layer covers conditioning, correction, out-of-sample records, and maintenance. The homepage currently exposes the method and pricing logic, but says the product itself is still being built and has no login yet.
