Widgets for traders on Angular

Our Company has developed interactive, customizable widgets for trading platforms, analytical services and fintech. We have implemented complex logic for working with exchange data, provided integration with API and protection from illegal use.
Project goal: Creation of custom widgets for displaying stock exchange data with the possibility of licensing and embedding into third-party services.

Implemented functions:

• The project was implemented from UI/UX design to backend and security system implementation.
• 7 widgets – quote charts, data tables, indicators of selected symbols, etc.
• Unique widget design and sales page, developed according to the client's instructions.
• Dynamic data update - all controllers on the demo page work in real time, changes are displayed instantly. Convenient interface for setting up and testing before purchasing.
• API integration - integration with exchange APIs and instant information update.
• Custom data security scheme , protection of received data (backend). License verification mechanism to protect against piracy.
