✨ No code. No finance degree. Just your hunch.

Got a trading idea? Turn it into an audited strategy — and find out if it actually works.

You don't need to know how to program, or how a backtesting engine works, to test a real hunch. Describe it in plain English, and quantstr.at turns it into a real trading strategy, runs it against real market history, and shows you what would have actually happened — the truth, not just a guess.

TWO WAYS TO WORK WITH US

Invest in a strategy, or build your own

Put money behind a strategy we've already built and audited — or use the app and chatbot to design, test, and refine a strategy of your own.

💰
Invest
Invest in a precomputed strategy
Pick a strategy from our library of pre-backtested, audited strategies and invest directly — orders are placed through our brokerage partner, Alpaca. No coding, no manual backtesting required.
✎
Build your own
Design it yourself
Describe your idea to the chatbot and let the AI build it, or add indicators, signals, entries, exits, and stops yourself, one step at a time. Nothing is pre-decided.
🔧
Build your own
Customize a precomputed strategy
Load any library strategy into the editor, change the indicators or thresholds you don't like, and backtest your own version right alongside the original.

Investing involves risk, including possible loss of principal. Backtested and historical performance is not a guarantee or reliable indicator of future results. Nothing here is personalized financial, investment, or trading advice. Brokerage services and trade execution are provided by Alpaca.

HOW IT WORKS

From an idea to an audited backtest

Every backtest runs the same pipeline behind the scenes — and nothing gets shown to you until a second AI has independently checked the work.

1
Describe it
Write your strategy idea in plain English — no code, no JSON, no indicators to wire up by hand.
2
AI builds it
Design, indicator, and signal agents turn your words into a real strategy: entries, exits, stops, and position rules.
3
It gets audited
A second, independent AI reviews the implementation against your original strategy and flags any mismatch — automatically, before you see results.
4
You get the numbers
Return, Sharpe ratio, drawdown, win rate, profit factor, equity curve, and a full trade log — ready to export.

✎
Plain-English strategy input
Type one sentence about what you want to trade. quantstr.at turns it into a fully specified strategy with real indicators, signals, and rules.
Describe your strategy.
