We’re excited to introduce Prax — a web platform that makes trading backtesting accessible to everyone. Whether you’re a retail trader looking to practice strategies, a quant-curious developer exploring ML models, or a prop firm training new traders, Prax has you covered.
What Makes Prax Different
Traditional backtesting tools are either too complex for beginners or too limited for serious analysis. Prax bridges that gap with:
- Manual Backtesting — Replay historical price data for any market and practice placing trades as if you were trading live. No coding required.
- Community Data — Browse and use datasets uploaded by other traders, covering markets worldwide. Upload your own data to share or keep private.
- AI/ML Model Building — Build and backtest machine learning models through a conversational interface. Describe what you want in plain English and let Prax handle the rest.
- Synthetic Data — Generate unlimited synthetic price data for practice and model training, so you never run out of scenarios to test.
Free to Start
Manual backtesting on Prax is completely free. Create an account, pick a dataset, and start replaying markets in minutes. AI and ML features use a credit-based system — buy only what you need.
We’re just getting started, and we’d love your feedback. Sign up at app.prax.trade and let us know what you think.
