Check out the new article: Interactive Supply and Demand Zone Manager in MQL5 (Part IV): Trading Supply and Demand Zones.

We extend the supply and demand framework with a strategy layer that converts zone interactions into decisions. Qualified zones pass sequential checks for interaction proximity, approach behavior, higher‑timeframe alignment, and price action before execution is handed to a dedicated trade manager. This architecture improves control, maintainability, and future extensibility without changing the underlying zone engine.

The architecture is divided into three independent responsibilities:

• Zone Analysis Layer: The existing zone engine remains responsible for detecting, scoring, and managing market structures. It provides the strategy layer with data such as zone location, boundaries, structural quality scores, lifecycle states, breakout/pending statuses, and interaction history. The strategy module consumes this information without modifying it, evaluating whether current conditions justify an entry.
• Strategy Decision Layer: The strategy module introduces a sequential evaluation process that validates zone qualifications, confirms price interaction, classifies approach behavior, verifies higher-timeframe conditions, and confirms price action confirmation patterns. Each stage acts as a filter, reducing trade entries based on incomplete information.
• Execution Layer: Once a valid signal passes the decision pipeline, execution is delegated to the trade manager module. This separation prevents order-handling logic from becoming tightly coupled with analytical logic.

This design allows the framework to evolve beyond a single trading approach. New analytical filters, alternative entry models, or advanced risk-management systems can be introduced without requiring major changes to the underlying supply and demand framework.
