About This Indicator
The Spline Quantile Regression Channel uses a non-linear spline curve to follow price, then wraps it with quantile regression bounds at configurable upper and lower percentiles (e.g. 85th/15th). The result is a statistically meaningful channel that adapts to price volatility while remaining smooth and visually clean.
Unlike simple Bollinger Bands, which use standard deviation, quantile regression does not assume a normal distribution making it more robust in trending or skewed markets where price rarely distributes symmetrically.
Key Features
- Non-linear spline fit tracks price curves more accurately than linear regression
- Configurable quantile percentiles for upper and lower channel boundaries
- Channel width adapts dynamically to current volatility regime
- Colour-coded fill between median and bands for instant visual context
- Alerts when price breaks above upper or below lower channel
- No repainting all values confirmed on bar close
How to Use
- Price touching the upper band in an uptrend = strong momentum, not automatically overbought
- Price rejecting from upper band after a failed breakout = high-probability short entry
- Median spline crossing = potential trend change signal
- Use on 4H and Daily timeframes for cleaner signals
- Combine with volume confirmation to filter false channel breaks
