Create a platform where users can build, test and paper-trade quantitative investment strategies without immediately risking real capital.

A Next.js frontend connects to a FastAPI backend and PostgreSQL database, with historical market data feeding a backtesting and paper-trading engine.

Built the platform around formula-based strategies, historical data and benchmark comparisons, prioritising honest performance measurement over pretending simple signals can reliably beat the market.

A working platform capable of running strategy logic against historical market data and evaluating performance against benchmarks.

Simple combinations of technical and fundamental signals can easily look better in testing than they perform in reality, making overfitting and honest evaluation major concerns.

Early-stage quantitative research and paper-trading platform.

Expand the strategy engine and testing framework with stronger validation, transaction costs and more realistic execution assumptions.
