    Scan library · 45 ready-made scans

    Every scan sits an exam. Then we rank them.

    Other sites rank scans by likes. We rank them by one simple, honest test.

    1Practice

    We run the scan on older data. Every time it picks a stock, we hold it 10 trading days and pay 0.2% in costs.

    2Exam

    Then we run it on newer data it has never seen. A scan that only works in practice just memorised the past, like a student who learned the answers.

    3Rank

    Scans that passed the exam come first. Passed means: it beat the average stock in practice, and still beat it in the exam by at least half as much.

    Edge = how much better the scan's picks did than the average stock on the same days, after costs. Example: +1.00% means its picks beat the average stock by 1% per trade. Sample data: this shows how the test works, not real results.

    Questions

    Straight answers

    Is this real market data?

    No. This demo uses 450 made-up sample stocks so you can try every feature. At launch we use licensed US market data, end of day first.

    Which markets come first?

    US stocks first. Then more markets one by one, such as Canada, the UK and India.

    Do I need to know coding?

    No. Type what you want in simple English, or pick rules from simple blocks. A formula view is there for power users.

    Why did so few ready-made scans pass the exam?

    Because most popular scans do not beat the average stock once you count costs. Other sites hide this. We show it, so you do not risk money on a scan that only looked good on old data. This demo uses sample data, so the exact results here are only an example.

    Which languages do you support?

    You type scans in simple English. The demo explains every scan back in 13 languages: English, Spanish, Portuguese, French, German, Indonesian, Vietnamese, Turkish, Arabic, Hindi, Marathi, Japanese and Chinese. For launch we plan to use AI to add more languages, and to let you type scans in your own language too.

    Is this investment advice?

    No. It is a tool that finds stocks matching your own rules and shows how those rules did in the past. You decide what to trade.

    Will there be a phone app?

    Yes. The website installs on your phone like an app. A Play Store version comes later.
