Polynomial Deviation Bands

3 天前

This indicator applies polynomial regression of selectable degree (1st to 4th) to recent price data, fitting a smooth curve that models the underlying price trend more flexibly than linear regression.

Around this polynomial regression line, it plots dynamic deviation bands calculated using a variety of selectable methods—including standard deviation, mean/median absolute deviation, exponential deviation, true range deviation, Hull, Frama, Kaufman adaptive, Gaussian weighted, and quantile deviation—providing a comprehensive view of price volatility and dispersion.

Key Features:

• Polynomial regression fit updated on each bar, capturing nonlinear price trends.
  
• Multiple deviation calculation options allow customization of band sensitivity and robustness.
  
• Bands adjust dynamically to changing volatility and price behavior.
  
• Overlay on price chart with optional candle coloring based on trend signals derived from price relative to bands.
  
• Trend signals indicated by price crossing upper or lower bands.
  
• Useful for identifying trend direction, potential support/resistance, and volatility expansion/contraction.
  

This tool combines advanced statistical modeling with flexible volatility measures to help traders better understand price structure and make informed trading decisions.
The indicator is computationally efficient despite polynomial fitting and offers extensive customization for diverse trading styles and markets.
