Tradr (tradr.it.com) is a free web trading game for practice and competition—not real-money trading or financial advice. You trade on a TradingView-style chart while algorithmic bots (RSI scalping, EMA trend, Darvas-style breakouts) trade the same market. Rounds last three minutes; highest return wins. ## Modes - **Solo**: Random or historical markets (forex, gold, stocks, crypto daily data). - **Multiplayer**: Shared seeded rooms; lobby lists open rooms with traders waiting. - **Community gallery**: Anonymous run replays; **Play alongside** lets you trade live while a recorded session replays as a "Peer trader" bot. ## Tech Next.js, TypeScript, canvas chart, Supabase Realtime + Postgres for multiplayer and gallery. ## Keywords trading game, browser trading game, paper trading simulator, algorithmic trading bots, multiplayer trading game, free trading game, Tradr
