Open tool

Rolling Hurst Calculator

Regime Detection

Track how the Hurst exponent changes over time to detect regime shifts between trending and mean-reverting behavior.

Open tool

Cycle Period Finder

Cycle Detection

Detect dominant cycle lengths in any price series using the Goertzel algorithm. Identify the periods most likely to drive future price action.

Open tool

Bartels Significance Test Calculator
