OpenTrade

OpenTrade is a multiplayer stock trading simulator where you compete with friends using simulated money on real stock tickers. The game includes AI opponents that mimic market behavior and react to news. The site offers one-tap Google sign-in, live leaderboards, and a clean mobile-first interface. It started as a weekend project and grew into a full game with over 4000 stocks tracked. No real money changes hands; the focus is on learning market mechanics and social competition.

The live site works as of 2026-08-26, with a husky mascot ("Gary") and a straightforward onboarding flow. The stack appears to be a modern React-based web app backed by a Node.js API and Firebase for authentication. No open-source repo is linked.

This belongs in the catalog because it's a finished, playable game that uses real stock data — not a toy demo. Builders can examine the UI patterns and game mechanics for their own simulation projects.
