Test a hundred trading ideas before lunch.
Describe your strategies in plain English. Your AI turns each one into a real backtest, runs them against years of market data, and hands back the numbers — dozens at a time, in seconds.
One prompt, sixteen backtests
ran in 218 ms · 5 worth a second lookMost ideas do not work. Finding that out in seconds — instead of after a month of manual testing, or a year of real money — is the entire point.
You already know how to use it.
There is no strategy builder to learn and no code to write. You describe what you want to test, in a sentence, to the AI you already use.
Only the first is worth keeping — and it still lost to simply holding BTC.
Say it in a sentence
“Buy dips in an uptrend.” “Try RSI between 20 and 40.” “Compare these three on ETH.” No syntax, no builder, no code.
It tests everything you asked for
Each idea becomes a real backtest over years of minute-to-daily history. Ask for a range and it sweeps hundreds of variations at once.
You get numbers, not opinions
Return, drawdown, win rate, Sharpe, every individual trade, and an equity curve — for each idea, side by side.

Ask for a backtest
In any chat, just say what you want:
A full report for every idea you test.
Equity curve
What your balance did, bar by bar, with drawdown underneath.
Every trade
Entry, exit, P&L and what closed it — stop, target or signal.
Risk numbers
Sharpe, Sortino, Calmar, max drawdown, exposure, win rate.
A market benchmark
What simply holding the asset would have returned instead.
Parameter sweeps
Hundreds of variations at once, ranked, with the weak ones rejected.
Forward testing
Promote an idea and watch it run on data it has never seen.
Real costs
Fees, slippage and funding charged — leverage checked for liquidation.
Shareable reports
Every result gets a link you can send to anyone.
Every number is computed the way a real broker would fill you, not the way that flatters the chart. How we calculate results →
