Describe the idea. Own the rules.

Plain English becomes buy rules, sell rules, and risk management you can edit in the condition builder — not a black-box prompt.

drafting rules

Buy when RSI dips below 30 after a 20-day high breakout. Trail an 8% stop. Scale in with 2% of equity per signal.

Candidate strategy — edit anything before you validate.

Buy rules
RSI(14) < 30 close > rolling_max(close, 20d)
Sell rules
RSI(14) > 70 trailing_stop(8%)
Risk management

Questions before signup

Which markets are supported?

Stocks, ETFs, forex, crypto, futures, and commodities, across US, UK, AU, CA and EU retail-accessible venues. Options aren't yet — we'd rather do them well later than badly now.

Is this a backtesting tool?

It contains a backtest engine, but it's not the product. The product is the candidate strategy itself — testable in the engine, editable in the rule builder, persistable as a versioned document.

What's a candidate strategy?

Buy rules, sell rules, and risk management. Saved as a versioned document so it survives schema changes and rolls into the language as it evolves.

What happens before signup?

You describe an idea, we generate rules, you preview where they fire on a chart. No backtest runs until signup, with state preserved.

Why not just predict returns?

Because nobody can reliably, and pretending otherwise is the entire problem with this category. We do evidence, not predictions.

Is my market activity private?

Yes. We don't share, sell, or surface what you backtest. Strategy documents are yours.
