Chaikin Money Flow with Shaded Backgound

This script is a modernized version of Chaikin Money Flow with time‑horizon presets, Histogram Mode, and Regime Background Shading.

Preset Modes

• Daily – Standard (20): Classic CMF(20), ideal for swing trading.
  
• **Weekly – Short (5): Time‑scaled equivalent of CMF(20) for weekly charts.
  
• Monthly – Smooth (10): Long‑cycle accumulation/distribution smoothing.
  
• Manual: Full control over CMF length.
  

These presets are designed to maintain **consistent time‑horizon behavior** across different chart timeframes.

• Line: Traditional CMF line.
  
• Histogram: Momentum‑style histogram.
  
• Hybrid: Line + histogram.
  
• CMF‑SMA Mode: Histogram shows CMF minus its SMA.
  
• CMF Change Mode: Histogram shows bar‑to‑bar CMF acceleration.
  

Note: When using Histogram Mode, switch the Histogram Type input between CMF‑SMA and CMF Change depending on the style you want.

• Green: CMF > 0 (Accumulation)
  
• Red: CMF < 0 (Distribution)
  

This provides a clean, structural read of market pressure without cluttering the chart.
