Price Action Strength/Machine Learning Hybrid Score System

This indicator combines Price Action Strength (PAS) with a Machine Learning (ML) derived signal to form a dynamic hybrid momentum model. It helps visualize underlying trend quality and predictive strength, and includes optional Bollinger Bands for volatility context.

• PAS (Price Action Strength):
  Measures directional momentum using the slope of a linear regression and candle body bias. The slope can be normalized by ATR or price and is smoothed using EMAs for stability.
  
  
• ML Score:
  Computes a predictive signal using multiple technical features (such as distance from recent highs/lows, EMA change, SMA slope, and MACD histogram). The result is z-scored and smoothed via WMA for noise reduction.
  
  
• Hybrid Score:
  Dynamically weights PAS and ML signals. PAS dominates when ML confidence is low; ML influence increases as predictive strength rises. Produces a smooth, normalized hybrid curve oscillating around zero.
  
  
• Bollinger Bands (optional):
  Can be plotted on the ML smooth line, PAS normalized line, or Hybrid Score (selectable). Configurable length and multiplier to visualize volatility and overbought/oversold zones.
  
  
• Visualization:
  - PAS (blue), ML (orange), and Hybrid (aqua) plotted together.
  - Background shading indicates bullish (green) or bearish (red) hybrid momentum.
  - Optional Bollinger Bands for visual reference.
  
  
• Inputs:
  - PAS length, smoothing, and signal EMA
  - ATR normalization toggle
  - ML toggle, smoothing, and weighting scale
  - Bollinger Bands toggle, source, length, and multiplier
  
  
• Usage:
  - Hybrid Score above zero suggests bullish momentum
  - Hybrid Score below zero suggests bearish momentum
  - Bollinger Band extremes can highlight potential turning points
  - Better results on higher timeframes (i.e. 1H+)
