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
