venue. This page is a map. Order types, fees, and country rules each have their own page, linked below the table.
“Off by default” means the venue is disabled for a new app until AGG enables it for that app. Direct mode is enabled per organization. Ask your AGG contact for either. Read the venues disabled for your app from
disabledVenues on Get the per-app UI config (client.getAppConfig()).
POST /execution/orders on a venue that cannot be traded returns 400 with code: "venue_not_executable". Do not retry it. On a venue disabled for your app it returns 400 with code: "quote_app_blocked".
Collateral is what the venue spends. On a managed-balance venue, a buy bridges into it for you. See Funding. A Kalshi buy spends cash already in the user’s Kalshi account and moves no funds.
