Warming up

Scout reads public venue data — markets, caller records, resolved receipts — and never your account. It is not answering yet, so every question gets the same honest reply. Ask anyway: it costs nothing and stores nothing.

    Questions are not stored, and Scout never sees your account.

    How Scout answers

    Your record

    Nothing here yet. Claim a wallet or connect Kalshi and your own receipt card takes this slot — the same card that travels when you share it.

    • Record, calibration and biggest call, minted from venue data.
    • Losses printed beside the wins. There is no deleting a bad call.

    Calibration

    How often the things you called at 70¢ actually happen. It needs 25 resolved positions before TAIL will publish a number — under that, one lucky week reads as skill.

    • A Brier score over your resolved calls, not a win rate.
    • The formula is published, not described. Nothing here is a black box.

    Alerts

    Nothing to send yet. An alert has to reach you somewhere, and a follow list stored on this device has no inbox — so alerts land with accounts.

    • A caller you follow opens a position.
    • One of their markets finally resolves.
    • Daily or weekly: the calibration digest — what the callers you follow resolved, plus the one market move worth knowing. Off unless you ask for it.

    1. To doVerify a winPaste the wallet and sign: the win becomes a receipt, with the losses beside it. TAIL never holds funds and never asks for a key.
    2. WaitingShare your cardWaiting on the first verified win: the card that travels is minted from a record that is yours, and there is nothing of yours to send yet.
    3. CheckingFollow 3 tradersTheir receipts and their flow land in the feed above, newest first.
    4. WaitingSet one alertWaiting on accounts: an alert has to reach you somewhere, and a follow list stored on this device has no inbox. The one this list completes into is the calibration digest — Alerts says what it will carry.

    Historical results from verified exchange data. Not investment advice. Trading involves risk of loss.

    Nothing on this page is a record of real trading: the roster and the feed are illustrative sample data — not real traders, real positions or real results. Following is stored on this device only: it creates no account and sends no alerts.
