Kernel Regression Trend Line
KTrend – Non-Repainting Kernel Regression Trend (2025 Clean Version)
Ultra-clean, powerful, and completely non-repainting trend-following tool based on advanced Kernel regression (Rational Quadratic + Gaussian blend).
How it works:
• Uses two different kernel estimates with smart lag to detect genuine trend reversals
• Plots a thick, beautifully colored trend line (teal when rising, deep red when falling)
• Places precise, locked-in Bullish Flip (green triangle below bar) and Bearish Flip (red triangle above bar) signals only on confirmed bar close – zero repaint, ever
• Optional smoothing mode for even cleaner visuals
Features
✓ 100% non-repainting signals and line
✓ Minimal lag while staying extremely responsive
✓ Clean aesthetic – perfect for BTC, ETH, stocks, forex, any timeframe
✓ Built-in alerts for Bullish & Bearish flips
✓ Fully open source (MPL 2.0)
Default settings are already battle-tested and loved by thousands:
- Lookback Window: 11
- Relative Weighting: 8.0
- Regression Level: 25
- Lag: 2
Great on 1H–Daily charts, especially crypto and indices.
