How this page works

The server holds the partner's read-only Kalshi key and listens to their account stream. Every order they place and every fill shows here within a second.

When a partner order first appears on a series that is switched on under Markets, the server buys that contract on our account: bet cap contracts at up to the price cap, resting at the cap if it doesn't fill, plus an optional resting bond. Their size is ignored, sells are shown but never copied, and each partner order copies once.

With DEMO on, every copy is simulated and nothing reaches Kalshi. The master switch stops copying entirely.

Markets we copy

How this page works

Each row is a Kalshi series (market family). Switch a row on and the server copies the partner's buys in every market of that family. Leave the cap boxes blank to use the defaults from Settings, or type a number to override just that family.

Series the partner trades that aren't in the catalog appear at the bottom, switched off, as soon as they show up in the stream.

Copier

Master switchOff = watch only. Nothing is placed, simulated or real.
Demo modeOn = every copy is simulated. Off = REAL MONEY on our account.

Caps (defaults for every series)

Bet capContracts per copy. The partner's size is ignored.
Price capCents per contract, max we pay for the side we buy (1–99). Unfilled size rests here.
Bond capExtra contracts left resting at the price cap after each copy. 0 = no bond.

Accounts

Rules

Once per marketNever copy a second time into the same market and side.
Follow partner cancelsIf they cancel an order we copied, cancel our resting remainder.
Max copies per hourSafety brake. 0 = no limit.
Ignore orders older thanSeconds. Backfilled orders older than this are never copied.

Fixed rules: a copy fires on the partner's order placement, is sized by our bet cap, and only buys are mirrored.
