TradePi

TradePi simulates the core infrastructure of a real stock exchange — from order placement to trade execution. The platform runs a custom matching engine that pairs buy and sell orders using price-time priority, just like production exchanges. Two markets run live with dedicated market makers continuously adding liquidity, so there's always action in the orderbook.

Built for anyone who wants to see what happens behind the trade button — real-time WebSocket feeds push orderbook depth and price updates to the UI the moment a match happens, while candlestick charts aggregate live trade data to show market momentum as it forms.
