Weighted Regression Bands (Zeiierman)

█ Overview
Weighted Regression Bands is a precision-engineered trend and volatility tool designed to adapt to the real market structure instead of reacting to price noise.

This indicator analyzes Weighted High/Low medians and applies user-selectable smoothing methods — including Kalman Filtering, ALMA, and custom Linear Regression — to generate a Fair Value line. Around this, it constructs dynamic standard deviation bands that adapt in real-time to market volatility.


The result is a visually clean and structurally intelligent trend framework suitable for breakout traders, mean reversion strategies, and trend-driven analysis.


█ How It Works

⚪ Structural High/Low Analysis
At the heart of this indicator is a custom high/low weighting system. Instead of using just the raw high or low values, it calculates a midline = (high + low) / 2, then applies one of three weighting methods to determine which price zones matter most.

Users can select the method using the “Weighted HL Method” setting:

• Simple
  Selects the single most dominant median (highest or lowest) in the lookback window. Ideal for fast, reactive signals.
  
• Advanced
  Ranks each bar based on a composite score: median × range × recency. This method highlights structurally meaningful bars that had both volatility and recency. A built-in Kalman filter is applied for extra stability.
  
• Smooth
  Blends multiple bars into a single weighted average using smoothed decay and range. This provides the softest and most stable structural response.
  

⚪ Smoothing Methods (ALMA / Linear Regression)

• ALMA provides responsive, low-lag smoothing for fast trend reading.
  
• Linear Regression projects the Fair Value forward, ideal for trend modeling.
  

⚪ Kalman Smoothing Filter
Before trend calculations, the indicator applies an optional Kalman-style smoothing filter. This helps:

• Reduce choppy false shifts in trend,
  
• Retain signal clarity during volatile periods,
  
• Provide stability for long-term setups.
  

⚪ Deviation Bands (Dynamic Volatility Envelopes)

• The indicator builds ±1, ±2, and ±3 standard deviation bands around the fair value line:
  
• Calculated from the standard deviation of price,
  
• Bands expand and contract based on recent volatility,
  
• Visualizes potential overbought/oversold or trending conditions.
  

█ How to Use

⚪ Trend Trading & Filtering

• Use the Fair Value line to identify the dominant direction.
  
• Only trade in the direction of the slope for higher probability setups.
  

⚪ Volatility-Based Entries

• Watch for price reaching outer bands (+2σ, +3σ) for possible exhaustion.
  
• Mean reversion entries become higher quality when far from Fair Value.
  

█ Settings

• Length – Lookback for Weighted HL and trend smoothing
  
• Deviation Multiplier – Controls how wide the bands are from the fair value line
  
• Method – Choose between ALMA or Linear Regression smoothing
  
• Smoothing – Strength of Kalman Filter (1 = none, <1 = stronger smoothing)
