Demand & Supply Zone Indicator: Precision Market Structure with Real-Time Alerts

Key Features of the Script:

1. Market Structure and Trend Analysis:
   • Detects Break of Structure (BOS) and shifts in market sentiment dynamically.
   • Tracks higher and lower price swings using ZigZag methodology for visualizing trends.
2. Demand and Supply Zones:
   • Highlights Bullish Order Blocks (Bu-OB) and Bearish Order Blocks (Be-OB).
   • Identifies breakout zones using Fibonacci factors for confirmation.
3. Bullish and Bearish Breakout Boxes:
   • Tracks Bullish and Bearish Breakout Boxes (Bu-BB, Be-BB) with dynamic visualization.
   • Adjusts zones as price action develops, ensuring real-time relevance.
4. Dynamic Alerts for Price Interaction:
   • Sends alerts when price enters or exits demand and supply zones (e.g., BU-OB, BE-OB).
   • Provides additional alerts for price presence within breakout boxes.
5. Custom Visualization:
   • Fully customizable box colors, borders, and text labels for clarity.
   • Displays BUY/SELL labels for breakout zones on the chart.
6. ZigZag Trend Line Integration:
   • Includes ZigZag trend lines connecting key swing points.
   • Visualizes market transitions between bullish and bearish phases.

Recommended Usage:

1. Scalping:
   • Suitable for 5-minute to 15-minute charts.
   • Use BU/BE zones to identify quick entry and exit points in volatile markets.
2. Swing Trading:
   • Effective on 1-hour to 4-hour charts for monitoring larger price swings.
   • Track BOS and Fibonacci breakouts to confirm macro trends.
3. Intraday Trading:
   • Ideal for 30-minute to 1-hour charts.
   • Combine OB zones with breakout alerts to capitalize on intraday momentum.
4. Risk Management:
   • Utilize supply and demand zones to set stop-loss and take-profit levels.
   • Monitor alerts for price interaction within OB and breakout zones.
