Practice. Analyze. Predict.
Replay any market risk-free. Then hand your results to an AI agent that cleans your data, picks the right model, and trains it for you — like having a quant on call.
One platform, the whole journey
Most tools stop at charts. Prax takes you from raw practice to AI-driven insight — whether you trade forex, crypto, stocks, or markets nobody else covers.
Bring Any Market
Upload your own data or browse what other traders have shared. Thai SET, Nigerian NGX, niche crypto — if you have the data, Prax can replay it.
Your Own AI Quant
An AI agent that works like a personal data scientist — it cleans your data, engineers features, selects the right model, trains it, and backtests it. You just describe what you want.
Start Immediately
No data to upload? Practice right away on synthetic and seed datasets. Get into your first session within a minute of signing up.
Built for Teams
Prop firms can assign scenarios to traders, track performance across the team, and pool AI credits — all from a shared workspace. Free to set up.
Like having a quant who never sleeps — it reads your trades, builds the models, and runs the backtests while you focus on strategy.
1. Pick your market and replay
Upload your own price data or choose from community-shared datasets and synthetics. Hit play and watch the market unfold candle by candle — fast-forward the boring parts, slow down when it matters.
2. Trade it like it's live
Place entries, set stops, manage risk — everything you'd do with real money, except here it costs you nothing. Every decision is tracked so you can review what worked and what didn't.
3. Let the agent do the heavy lifting
Point the AI at your session and tell it what you want to know. It reads your trades, cleans the data, engineers features, picks the right training model, and runs the full pipeline — following ML best practices so you don't have to.
4. Iterate, backtest, repeat
Run your model against new data. Not happy? Tell the agent to try a different approach — it can train multiple models in parallel, compare results, and fine-tune until the numbers make sense.
