Known Limitations

1. API Dependency

   • Pages require backend APIs to be running
   • Fallback data is minimal
   • Some features require HuggingFace models to be loaded

2. Chart Rendering

   • Requires Chart.js library to be loaded
   • May fail if OHLCV data is unavailable
   • Gracefully degrades to error state

3. Model Loading

   • Models must be initialized on backend
   • Some models require authentication
   • Loading can take time on first request

Future Improvements

1. AI Analyst

   • Add more technical indicators
   • Implement real-time updates via WebSocket
   • Add historical analysis comparison
   • Implement custom timeframe selection

2. Models Page

   • Add model performance metrics
   • Implement model comparison feature
   • Add model training history
   • Implement batch testing

3. General

   • Add caching for API responses
   • Implement progressive loading
   • Add export functionality
   • Improve mobile responsiveness

Deployment Notes

1. No Backend Changes Required

   • All fixes are frontend-only
   • Existing API endpoints are used
   • No database migrations needed

2. Browser Compatibility

   • Modern browsers (Chrome, Firefox, Safari, Edge)
   • Requires ES6+ support
   • CSS Grid and Flexbox support required

3. Dependencies

   • Chart.js 4.4.1 (loaded from CDN)
   • No additional npm packages required
