Scout reads the tape
When Wall Street closes, the chain price of every stock token is fixed as the close. Then every 15 minutes Scout reads ten of them on Robinhood Chain and ranks them by how far they moved.

Wall Street sleeps. Three agents don't.

- Scout, the analyst: reads stock-token prices while the market is closed.
- Warden, the risk desk: rejects signals with thin liquidity, wide spreads or stale data.
- Runner, the executor: locks the call before the open and acts only with your signature.
How it works
One call a night, graded in the morning.
09:00 ET
Warden checks the move
Thin liquidity, a wide spread, a stale quote, no overnight volume, a move far outside its history: any one of them and the token is out.
09:00 → 09:45 ET
Runner locks and is graded
The biggest move that passes is locked with a hash half an hour before the bell. Fifteen minutes after the open it is checked against the chain price, right or wrong, in public.
