Supply/Demand HTF (RBD/DBR) – FIX + Debug

Overview:
This indicator automatically detects and plots institutional supply and demand zones on any timeframe.
It analyzes price action to identify Drop-Base-Rally (DBR) and Rally-Base-Drop (RBD) structures — the core formations of supply and demand trading.

How It Works
1. The script scans price candles to detect “base” formations — small consolidation candles between impulsive moves.
2. When it finds a valid base followed by a strong move, it marks that area as:
• 🟩 Demand Zone (DBR): price dropped → consolidated → rallied upward
• 🟥 Supply Zone (RBD): price rallied → consolidated → dropped downward
3. Each detected zone is extended to the right so you can see if price returns to it later.
