The Kaufman efficiency ratio (net move / total path) is a second read on trend cleanliness. asset returns one instrument's Hurst, efficiency ratio and regime label; screener ranks the cross-asset universe from most trending to most mean-reverting. The persistence / trend-vs-mean-reversion regime cut — distinct from the z-score stretch gauges, the multi-timeframe momentum-alignment API and the price APIs.",
