the US market is shut

Your broker sleeps 80% of the week. Talos doesn't.

Write a rule in plain English. SERV Reasoning turns it into a flowchart you approve, and Talos replays it on every real night and weekend first. Then it keeps watch, and sells your NVDA on Robinhood Chain only when your rule and the market both say so.

1

Your rule

Talos can only sell NVDA for USDG, from one small wallet with a cap.

SERV reads your rule, keeps your numbers exactly, and adds the checks you didn't think of.
2

Your flowchart

What you're looking at: your rule as a flowchart. Talos only sells if every check says yes. Checks marked Talos were added by SERV, with the reason.

What your rule would have done

What you're looking at: every real night and weekend since July, as bubbles. Flip between with Talos's checks and your rule alone and watch the bubbles move.

Approve, then Talos keeps watch

What you're looking at: Talos checking the market right now. SERV reads the Nvidia news since the close and judges whether real bad news is behind the drop, which code can't do. Then a small model walks your flowchart through SERV, Talos's code walks it too, and a sale needs both to agree.

The proof

What Talos has actually done, how well it holds up, and why every watch runs on SERV.

✓

Awake right now

Not a demo: Talos checks the live market every 15 minutes, on the quarter hour, whenever the US market is shut. Every check is a real SERV call, logged below.

Reading the watch log…
—checks while the market was shut, each with SERV reading the news and walking the flowchart
—times SERV and the code agreed
—sales. The rule:
NVDA since the last close, against the rule's trigger

The watch runs on a schedule on GitHub and has no wallet key, so it can't sell; it shows the decisions. Sales go through the separate, capped guard. How it runs · raw log

How Talos checks
reads your $SERV balance on Base, every month
Where it sells
Robinhood Chain, as always
Talos sold, and the price kept falling to the open
a 10% fee on what it saved you
Talos sold and the price came back, or it held
no fee

Connect a wallet and Talos reads its $SERV balance on Base. It's read only: no transaction and no bridge, and the same address works on both chains. Access lasts while the $SERV is held. That's a reason to use $SERV, not a promise about its price. Example fee: Talos sells $500 of NVDA at 2 AM and it's worth $470 at the open, so it saved you $30 and keeps $3.

Every watch runs on SERV

Talos checks every 15 minutes whenever the US market is shut. Each check is one SERV Reasoning call on the cheapest model, which only works because the rule is a flowchart.

542SERV calls a week for one person watching NVDA
$0.49SERV spend per person per month, small model through SERV
$21.25the same checks on a frontier model, per person per month
At scale

Measured costs from the scoreboard: $0.21 per 1,000 checks through SERV, $9.05 on a frontier model. OpenServ puts 25% of SERV Reasoning revenue into buying and burning $SERV. Talos's own pricing is a separate question: a flat monthly fee per ticker watched, with the option to pay in $SERV.
