Updated Demand Index (James Sibbet)

This indicator is a faithful implementation of James Sibbet’s Demand Index — a leading volume-price oscillator designed to anticipate trend reversals, confirm momentum, and highlight divergences between price and volume pressure.
Key Features
• Original Sibbet Formula with H + L + 2C price input and 0.375 exponential factor.
• Buy/Sell Power Calculation with EMA smoothing (ATAS default settings).
• Demand Index SMA for trend confirmation.
• Zero-Line Centering for quick bullish/bearish identification.
• Red/Green Coloring for immediate sentiment visualization.
How to Use
1. Above Zero → Bullish pressure dominates (green).
2. Below Zero → Bearish pressure dominates (red).
3. Divergences → Price making new highs/lows without confirmation in DI often precedes reversals.
4. Use DI SMA for signal smoothing and better trend filtering.
