Trading Journal

A personal trading journal platform for tracking trades, analyzing performance metrics, and identifying patterns across multiple asset classes with real-time P&L tracking.

Die Herausforderung

Traders needed a structured way to log trades, review mistakes, and measure performance over time without relying on scattered spreadsheets and manual calculations.

Die Lösung

Built a full-stack journal app with React frontend, NestJS backend, and PostgreSQL. Implemented interactive charts for equity curves and win-rate analysis, real-time P&L calculations, and a tagging system for trade setups and patterns.
