How it works
1
Describe the idea
Write an entry, an exit, or simply the behaviour you want. For example: “Buy BTC when momentum turns positive, trail the position with ATR, and exit when the trend breaks.”
2
The lab writes and tests it
The lab writes the strategy as prompt logic, then backtests it. It keeps running if you leave the lab; the result is waiting when you come back.
3
Refine it in conversation
Ask for changes such as “make entries stricter”, “add an RSI filter” or “reduce drawdown”. Each accepted revision is tested automatically.
4
Create the live strategy
When you’re happy with it, choose Create live strategy.
Editing directly
The Prompt logic is editable. After you stop typing, it’s re-tested automatically. You can also change the test settings: Market, Candles, Default qty, Starting capital, Max leverage, Fee and Slippage (in basis points), Confidence and the start date (From).Results
Each test shows Net return, Ending equity, Max drawdown, Trades, Win rate, Sharpe, Sortino and Profit factor, with the equity curve and the drawdown path. Prompt coverage shows how much of the prompt the backtest could test: parts included, partial and unsupported. See Reading a Fast Estimate.Lab backtests are Fast Estimates: candle-based approximations, not replays of live AI decisions. They run in your browser and don’t use AI credits.
