TradeSphere: A Full Stack Web-based Stock Trading Platform Using MERN Stack

Abstract: The rapid expansion of financial markets and the increasing participation of students, young professionals, and first-time investors in stock trading have created a strong demand for educational tools that simplify the understanding of market operations. In recent years, digital trading platforms have become highly popular due to the availability of smartphones, internet access, and low-cost investment options. However, most existing trading applications are designed for professional traders and real investors, making them complex and difficult for beginners to understand. These platforms generally include advanced trading charts, multiple financial indicators, margin calculations, technical analysis tools, and live market data, which may overwhelm new learners. As a result, there is a growing requirement for a simplified educational trading system that can help users understand the core concepts of stock market trading without involving real financial risk.
This paper presents TradeSphere, a simulation-based full-stack web application developed to provide an easy, structured, and accessible environment for learning the basic functionalities of a stock trading platform. The system has been designed mainly for students, academic demonstrations, and beginner-level users who want to understand how modern online trading systems work. Instead of interacting with actual stock exchanges or real money transactions, TradeSphere simulates the major components of a stock trading dashboard, including stock holdings, market positions, order placement, and portfolio management.
