Abstract: The increasing complexity and volatility of modern financial markets have amplified the challenges faced by individual investors in making timely and informed trading decisions. While institutional participants benefit from advanced analytical infrastructures, retail investors often rely on fragmented tools that lack real-time intelligence, integration, and interpretability. TradeNexus AI – AI that Thinks Finance addresses this disparity by presenting an AI-driven decision support platform designed to assist investors through unified, explainable, and data-informed market insights. The system focuses on reducing information overload and emotional bias by transforming diverse financial data into structured, actionable guidance.

TradeNexus AI integrates three complementary dimensions of market intelligence: technical analysis, fundamental analysis, and news-based sentiment analysis. Technical indicators such as RSI, MACD, and SMA capture short-term market momentum, while fundamental evaluation of financial ratios assesses long-term asset strength. In parallel, natural language processing models analyze financial news to quantify market sentiment. These heterogeneous signals are synthesized through a Weighted Fusion Decision Engine, which generates Buy, Sell, or Hold insights based on consensus logic, thereby enhancing decision reliability without relying on a single analytical perspective.

The platform is implemented using a scalable web architecture comprising a responsive frontend, a modular backend, integrated AI processing components, and a PostgreSQL-based data storage layer for secure management of user and portfolio information. By combining real-time analytics, artificial intelligence, and an interactive user experience, TradeNexus AI demonstrates how intelligent decision-support systems can democratize access to advanced financial analysis tools, enabling individual investors to engage with financial markets in a more structured, confident, and informed manner.
