This paper presents Predictiv, a full-stack real-time stock market platform designed to provide investors with comprehensive market data, financial analytics, and portfolio management capabilities. The system integrates multiple financial data sources including Yahoo Finance and Alpha Vantage APIs to deliver live price quotes, OHLCV candlestick charts, fundamental financial statements, and news sentiment analysis. The frontend is built using React.js with Redux state management, D3.js-powered charting via react-stockcharts, and a context- based dark/light theme system. The backend is implemented with Django REST Framework, providing secure JWT-based authentication and persistent portfolio and funds management. The platform features a three-tier data fallback architecture ensuring high availability, pre-loaded support for major Indian NSE stocks and global equities, and real-time market hours awareness for the National Stock Exchange of India. Results demonstrate that the system successfully delivers a responsive, data-rich trading interface suitable for both retail and research- oriented users.
