Add Supply & Demand Zone Detection + Drawing to Existing MT5 Indicator (Clear Rules Provided)

I need a developer to add Supply & Demand zone detection + drawing to my existing MT5 indicator. No rewrite. No restructuring. Just clean, precise integration into the current logic.

I will attach the indicator file.

1. DEMAND ZONE DETECTION (BUY continuation)

A Demand Zone must be created when:

1. A bullish displacement candle creates a Bullish FVG

2. The origin of the displacement (the last bearish candle before the displacement) becomes the Demand Zone

3. Zone boundaries:

   • Upper: Open of the last bearish candle

   • Lower: Low of the last bearish candle

4. The zone must sit below the Bullish FVG

5. The zone extends right until invalidation

6. Invalidation: a candle closes below the entire zone

2. SUPPLY ZONE DETECTION (SELL continuation)

A Supply Zone must be created when:

1. A bearish displacement candle creates a Bearish FVG

2. The origin of the displacement (the last bullish candle before the displacement) becomes the Supply Zone

3. Zone boundaries:

   • Lower: Open of the last bullish candle

   • Upper: High of the last bullish candle

4. The zone must sit above the Bearish FVG

5. The zone extends right until invalidation

6. Invalidation: a candle closes above the entire zone

3. VISUAL REQUIREMENTS

• Draw zones as rectangles

• Demand: green tint (low opacity)

• Supply: red tint (low opacity)

• Extend zones to the right until invalidation

• Zones must NOT repaint once confirmed

• Must not interfere with existing FVG drawing

• Must be visually clean and lightweight

4. INTEGRATION RULES

• Must integrate cleanly with existing FVG logic

• Must not break or alter current indicator behavior

• Must not introduce lag or heavy CPU load

• Must update only on new displacement events

• Must remain stable (no flickering, no repainting)

5. DELIVERY REQUIREMENTS

• Clean, readable code

• No rewrite of existing structure

• Only add the new logic

• Keep all existing inputs and visuals untouched

• Provide comments explaining the new functions
