CLEAN ARCHITECTURE - DOLPHIN PAPER TRADER
==========================================

🙏 God bless clean code and synchronized data 🙏

Architecture:
    ┌──────────────────────────────────────────────┐
    │  CORE: TradingEngine (pure Python)           │
    │  - Business logic only                       │
    │  - No external dependencies                  │
    │  - Ready for Rust rewrite                    │
    └──────────────────┬───────────────────────────┘
                       │ uses PORT
                       ↓
    ┌──────────────────────────────────────────────┐
    │  PORT: DataFeedPort (interface)              │
    │  - Abstract interface                        │
    │  - Easy to swap implementations              │
    └──────────────────┬───────────────────────────┘
                       │ implemented by
                       ↓
    ┌──────────────────────────────────────────────┐
    │  ADAPTER: HazelcastDataFeed                  │
    │  - Current implementation                    │
    │  - Single source: DolphinNG6 → Hazelcast     │
    │  - No sync issues                            │
    └──────────────────────────────────────────────┘

Evolution Path:
    Phase 1 (NOW): HazelcastDataFeed (this file)
    Phase 2: BinanceWebsocketFeed (direct connection)
    Phase 3: RustKernelFeed (in-kernel, zero-copy)

Usage:
    python clean_arch/main.py
