SIX Swiss Practice Exam

IMI is used to convey essential instrument attributes that traders need to trade consistently. The price tick size—the minimum price increment for an instrument—is such a fundamental parameter, and it must be shared across all participants so every order and quote adheres to the same price steps. Publishing the tick size through IMI ensures that bids, asks, and trades are priced on a common grid, which is why it is transmitted by IMI. Other items, like market data feed latency reductions, daily settlement amounts, or account login events, belong to performance metrics, settlement data, and security events, respectively, and are not core market-structure attributes transmitted by IMI.
