CodeBull is a paper trading platform where you practise on live market data, automate strategies with code or visual blocks, and compete against other traders — all without risking a single penny.
Free to use · No credit card required
Six pillars that take you from idea to insight.
Trade on live quotes from global markets or replay historical bars tick-by-tick to stress-test any idea without waiting for the market to cooperate.
Place market, limit, stop-loss, and trailing-stop orders against a realistic order book — all in a zero-risk paper environment that mirrors real exchange mechanics.
Write Python strategies or drag-and-drop logic blocks to automate trading rules. The engine runs your bot live or in simulation mode with full order management.
Replay years of historical data to measure how a strategy would have performed, then switch to live paper trading with a single click to see it in action.
Compete in timed arenas with other traders. Track rankings, see who builds the best strategy, and learn from top performers in a fair, sandboxed competition.
Detailed P&L reports, win-rate breakdowns, and equity curves to understand exactly where — and why — your strategy wins or loses.
Join traders sharpening their skills on CodeBull. It's free — and there's no money at risk.
