- Introduced a new modular structure for the dashboard, enhancing maintainability and scalability. - Created main application entry point in `app_new.py`, integrating all components and callbacks. - Developed layout modules for market data, bot management, performance analytics, and system health in the `layouts` directory. - Implemented callback modules for navigation, charts, indicators, and system health in the `callbacks` directory. - Established reusable UI components in the `components` directory, including chart controls and indicator modals. - Enhanced documentation to reflect the new modular structure and provide clear usage guidelines. - Ensured all components are under 300-400 lines for better readability and maintainability.
