  • Domain: Entities, value objects, aggregates, invariants. No external dependencies.
  • Application: Use cases, CQRS handlers, validators, interfaces.
  • Infrastructure: Databases, MT4/MT5 bridges, message brokers, external APIs.
  • Presentation: Controllers, endpoints, UI components.
  • Rule: Dependencies always point inward.
