Everything you need to practise trading

Six pillars that take you from idea to insight.

Real-time & Replay Market Data

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.

Manual Simulation

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.

Automated Bot Builder

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.

Backtesting & Paper Trading

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.

Leaderboards & Arenas

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.

Performance Analytics

Detailed P&L reports, win-rate breakdowns, and equity curves to understand exactly where — and why — your strategy wins or loses.
