What is listed here, and nothing extra to buy: no data key, no add-ons.
- AI research agentDescribe a strategy in plain English and get tested code, a backtest with costs and a verdict on the result.
- Cloud Python backtestingRun the generated code, or your own backtesting.py file, in a sandbox. Nothing to install.
- Honesty Score and validationDeflated Sharpe corrected for how many versions were tried, a cross-validation robustness check of the run’s own trades, and Monte Carlo resampling. None of them is an out-of-sample test.
- Prop-firm simulatorModelled pass odds for evaluations at 12 prop firms, and a check that the firm offers what your strategy trades (stock and ETF strategies: the CFD firms only, while futures are paused).
- Pine Script supportGenerate, repair and tune Pine strategies, or bring your own.
- Market data includedUS stocks and ETFs on daily bars (about 7.9 years per test by default, and all daily history with Max), intraday from IEX exchange prints, spot crypto and spot FX. No data key, no extra bill.
Nothing to pay until your place is confirmed. 14-day money-back guarantee on the first payment of each new subscription. Cancel any time.
Fair-use limits
- AI work
- A daily allowance that fits about 25 messages, around 10 of them with a backtest, and a weekly allowance of about 3 such days. Settings shows how much you have used, as a percentage.
- Chat messages
- 500 a day, and 20 a minute
- Backtests
- 200 a day
- Robustness checks (/validate)
- 50 a day
A backtest itself uses none of the AI allowance. Writing or changing a strategy uses it, and so do the assistant’s replies and any explanation you ask for. Your usage is shown in Settings; nothing is ever charged extra.
Questions
How do I get in?
Apply with a short form. We read every application and admit people in small groups; when your place is ready we email you a link to create your account, and you subscribe from there.
Am I charged when I apply?
No. Nothing is charged until your place is confirmed and you subscribe: €39 excl. VAT for your first month, then monthly. That rate stays yours for as long as you stay subscribed.
What happens to the price at the public launch?
It goes up for new members. Beta members who stay subscribed keep €39/month.
What if I change my mind?
Cancel any time from Billing in the app’s sidebar. The first payment of each new subscription carries a 14-day money-back guarantee: write to us through the support page and it is refunded, no questions. Consumers in the EU and EEA also have a statutory right to withdraw within 14 days of subscribing, with a proportionate deduction for the days you used the service; see section 15 of the Terms.
What market data is included?
Included: US stocks, ETFs and mutual funds on daily bars, split-adjusted (price returns; dividends are not included), about 7.9 years per test by default, and all daily history with Max; US stock intraday from 1 minute, drawn from IEX exchange prints only, which are solid on large names and thin on the rest; spot crypto pairs aggregated across exchanges, and spot FX pairs without volume, from 1-minute to daily; and the latest annual SEC 10-K figures as a lookup. A run on this data shows what the strategy did (returns, drawdown, win rate, its own equity), never the prices it traded at: our licence for this data covers results, so there are no price charts and no trade prices. CME futures are paused while we finalise the exchange data licence; they return when it is settled. Not included: options chains and tick prints.
Are there usage limits?
Yes, generous ones, so one account cannot degrade the service for everyone: AI work: a daily allowance that fits about 25 messages, around 10 of them with a backtest, and a weekly allowance of about 3 such days; chat messages 500 a day, and 20 a minute; backtests 200 a day; robustness checks (/validate) 50 a day. A backtest itself does not use the AI allowance; writing or changing a strategy does, and so do the assistant’s replies and any explanation you ask for. Settings shows how much of your allowance you have used, as a percentage, and a limit that is reached pauses that feature until it resets; nothing is ever charged extra.
How does payment work?
Secure checkout on Stripe; QuantWright never sees your card. Invoices, card changes and cancellation are under Billing in the app’s sidebar.
Is VAT included?
No. €39 a month is the price before VAT. EU consumers pay 25.5% Finnish VAT on top: €48.95 a month in total. The exact total is shown at checkout before you pay. A business in another EU country that gives a valid VAT number at checkout is reverse-charged instead. Outside the EU, where no VAT is due, you pay €39.
