How the admin side fits together. Reference Data describes what can be traded (instruments, product groups, settlement indices, calendars, expiries, costs). Clearing & Limits describes where it is traded and how much (clearers, accounts and their enabled instruments, trader limits at every level). Company holds who does it (hierarchy, users, roles, write scope). Every money-moving field goes through the four-eyes queue under Controls when it is switched on. Every table exports and imports the same CSV.
