Nadaraya-Watson Kernel Regression Breakout
Non-parametric Nadaraya-Watson kernel estimator calculating dynamic Gaussian regression bounds. Outliers touching the upper and lower kernel envelopes trigger high-probability statistical mean reversions back to the fitted fair-value curve.

Why do some Nadaraya-Watson scripts repaint?
Standard Nadaraya-Watson scripts look forward in time using future bars to smooth the curve. Backpulse provides a strictly causal, non-repainting implementation audited for live production trading.
