## Next Steps for Remaining UI Components

See `docs/UI_IMPROVEMENTS_SUMMARY.md` for detailed implementation guidance for:
1. Dashboard widgets
2. Advanced orders UI
3. Trade journal page
4. ML transparency widget
5. Chart drawing tools
6. Mobile touch optimization

## Testing Recommendations

1. **VaR Calculation**: Test with different confidence levels and holding periods
2. **Monte Carlo**: Verify statistical distributions

5. **Execution Algorithms**: Test TWAP/VWAP with various conditions
6. **Chart Indicators**: Verify indicator overlay rendering

## Performance Considerations

- Monte Carlo simulations: CPU-intensive (consider background processing)
- SHAP calculations: May be slow for large models (consider caching)
- Online learning: Batched updates for efficiency
- VaR calculations: Efficient numpy operations
