## Testing Notes

The following areas should be tested:

1. **Strategy Management**
   - Create/edit/delete strategies
   - Start/stop strategies
   - Parameter validation
   - Strategy type switching

2. **Trading**
   - Order placement (all order types)
   - Order cancellation
   - Position closing
   - Real-time updates

3. **Real-time Features**
   - WebSocket connection/reconnection
   - Message handling
   - Query invalidation on updates

4. **Error Handling**
   - Network errors
   - Validation errors
   - Backend errors
   - Retry functionality

5. **Loading States**
   - Skeleton loaders
   - Progress overlays
   - Button disabled states

## Documentation Updates Needed

1. **User Manual Updates**
   - Add Strategy Management section
   - Add Manual Trading section
   - Update Dashboard documentation
   - Update Portfolio documentation with new features
   - Update Settings documentation with alert history

2. **API Documentation**
   - Document WebSocket message types
   - Document new endpoints if any
   - Update response schemas

3. **Developer Documentation**
   - Component architecture
   - State management patterns
   - WebSocket integration guide
   - Error handling patterns

## Known Limitations

1. **Parameter Optimization**: UI structure is in place, but requires backend API endpoints for optimization methods (Grid Search, Genetic Algorithm, Bayesian Optimization)

2. **Advanced Order Types**: OCO and Iceberg orders have UI support but may need backend implementation verification

3. **Exchange Status**: Exchange connection status is displayed but may need backend health check endpoints for accurate status
