Unified codebase for multiple platforms
The same HTML, JavaScript, and CSS codebase is used for both web and mobile deployments, reducing duplication and maintenance overhead. The project structure supports generating hybrid packages for iOS and Android through IntelXDK without requiring separate implementations.
Custom Tradingview datafeed implementation
Contains a custom datafeed module in chart_library/datafeed that bridges Tradingview's charting library with Binary.com's trading data and API. This allows the charting interface to receive real-time market data specific to Binary.com's offerings.
Hybrid mobile packaging approach
Uses IntelXDK to generate native-like mobile applications from the web codebase, enabling distribution through standard app stores while maintaining a single source of truth for the application logic.
