Indicator Overview

The Nadaraya-Watson Z-Envelope is a refined volatility and mean-reversion tool that leverages non-parametric regression to create a dynamic price envelope.

Non-parametric regression is a flexible approach to data modelling that lets the actual points dictate the shape of the curve, rather than forcing them into a rigid, pre-defined mathematical formula like a straight line.

Based on the Nadaraya-Watson estimator with Gaussian weighting, this script produces a smoothed, adaptive central line alongside upper and lower bounds that respond to localised volatility—highlighting potential areas of overextension or reversion. The envelope's structure adapts in real time, enabling the identification of cyclical extremes and price inefficiencies with reduced lag.

How To Use

Traders can buy on lower band crossunders and sell on upper band crossovers. Investors may accumulate in oversold zones and reduce exposure in overbought periods, aligning with Bitcoin’s cyclical volatility patterns.
