| 84 | +## 🔄 Migration Guide |
| 85 | + |
| 86 | +### Upgrading from v3.1.x |
| 87 | + |
| 88 | +**Good news!** v3.2.0 maintains full backward compatibility. No code changes are required to upgrade. |
| 89 | + |
| 90 | +However, to take advantage of the new type safety features: |
| 91 | + |
| 92 | +1. **Update your type hints** to use the new TypedDict definitions: |
| 93 | +```python |
| 94 | +from project_x_py.types import OrderEventData, BarData, QuoteData |
| 95 | + |
| 96 | +async def handle_order(event: OrderEventData) -> None: |
| 97 | + order_id = event["order_id"] # Type-safe access |
| 98 | + # ... |
| 99 | +``` |
| 100 | + |
| 101 | +2. **Use Protocol types** for better component typing: |
| 102 | +```python |
| 103 | +from project_x_py.protocols import ProjectXClientProtocol |
| 104 | + |
| 105 | +def process_data(client: ProjectXClientProtocol) -> None: |
| 106 | + # Works with any client implementation |
| 107 | + # ... |
| 108 | +``` |
| 109 | + |
| 110 | +3. **Handle deprecations** properly: |
| 111 | +```python |
| 112 | +# Old method (deprecated) |
| 113 | +positions = await client.get_positions() # Will show deprecation warning |
| 114 | + |
| 115 | +# New method (recommended) |
| 116 | +positions = await client.search_open_positions() |
| 117 | +``` |
| 118 | + |
| 119 | +## 📦 Installation |
| 120 | + |
| 121 | +```bash |
| 122 | +# Upgrade existing installation |
| 123 | +pip install --upgrade project-x-py |
| 124 | + |
| 125 | +# Or with UV (recommended) |
| 126 | +uv add project-x-py@^3.2.0 |
| 127 | + |
| 128 | +# Fresh installation |
| 129 | +pip install project-x-py==3.2.0 |
| 130 | +``` |
| 131 | + |
| 132 | +## 🧪 Testing |
| 133 | + |
| 134 | +The SDK now includes comprehensive test coverage: |
| 135 | +- **47 new tests** for type system validation |
| 136 | +- **93% coverage** for client module (up from 30%) |
| 137 | +- **Full Protocol compliance** testing |
| 138 | +- **Task management** lifecycle tests |
| 139 | + |
| 140 | +Run tests with: |
| 141 | +```bash |
| 142 | +uv run pytest |
| 143 | +# Or with coverage |
| 144 | +uv run pytest --cov=project_x_py --cov-report=html |
| 145 | +``` |
| 146 | + |
| 147 | +## 📚 Updated Examples |
| 148 | + |
| 149 | +All 20 example scripts have been updated for v3.2.0: |
| 150 | + |
| 151 | +### Removed (Redundant) |
| 152 | +- `01_basic_client_connection_v3.py` (duplicate) |
| 153 | +- `06_multi_timeframe_strategy.py` (superseded) |
| 154 | + |
| 155 | +### Renumbered for Clarity |
| 156 | +- Examples now properly numbered 00-19 without duplicates |
| 157 | +- Clear progression from basic to advanced features |
| 158 | +- Separate section for real-time data manager examples |
| 159 | + |
| 160 | +### Example Structure |
| 161 | +``` |
| 162 | +00-09: Core functionality (basics, orders, positions, data) |
| 163 | +10-19: Advanced features (events, strategies, risk management) |
| 164 | +realtime_data_manager/: Specialized real-time examples |
| 165 | +``` |
| 166 | + |
| 167 | +## 🚀 Performance Impact |
| 168 | + |
| 169 | +The type system improvements have minimal runtime impact: |
| 170 | +- **Type checking**: No runtime overhead (types are ignored at runtime) |
| 171 | +- **Memory tracking**: < 1% overhead with valuable insights |
| 172 | +- **Event emission**: Actually improved to prevent deadlocks |
| 173 | +- **Overall**: Better performance through optimized patterns |
| 174 | + |
| 175 | +## 🛡️ Breaking Changes |
| 176 | + |
| 177 | +**None!** This release maintains full backward compatibility with v3.1.x. |
| 178 | + |
| 179 | +## ⚠️ Deprecations |
| 180 | + |
| 181 | +The following features are deprecated and will be removed in v4.0.0: |
| 182 | +- `client.get_positions()` → Use `client.search_open_positions()` |
| 183 | +- `OrderTracker` class → Use `TradingSuite.track_order()` |
| 184 | +- Legacy callback methods → Use EventBus handlers |
| 185 | + |
| 186 | +All deprecations include clear migration paths and will be supported until v4.0.0. |
| 187 | + |
| 188 | +## 🔮 What's Next |
