There are DCB (Dynamic Circuit Breaker) and SCB (Static Circuit Breaker).
DCB is a rule that from the viewpoint of preventing sudden price fluctuations, such as those caused by erroneous orders, trading is temporarily halted when an order bringing an execution outside of a set price range based on the last reference price is placed.
