Trading Pause Mechanics

Trading pause mechanics are the technical procedures that occur when a circuit breaker is triggered. These mechanics can include stopping all order matching, canceling all pending orders, or switching to a quote-only mode.

The objective is to stop the flow of trades to prevent the propagation of erroneous or panic-driven orders. Once the market stabilizes, the system then resumes trading, often with a pre-opening phase to allow for price discovery.

These mechanics are designed to be transparent so that all traders know exactly what to expect when a pause occurs. They are vital for restoring confidence in the market after a period of extreme stress.
