Circuit Breaker Systems

Algorithm

Circuit breaker systems, within financial markets, represent pre-planned interventions designed to mitigate systemic risk during periods of substantial and rapid price declines or increases. These mechanisms operate by temporarily halting trading in specific securities or across entire exchanges, providing a cooling-off period to prevent cascading liquidations and maintain orderly market function. Implementation relies on pre-defined thresholds, often based on percentage declines from a reference price, triggering single or multiple halts of varying durations. Modern adaptations increasingly incorporate velocity-based triggers, responding to the rate of price movement rather than absolute levels, enhancing responsiveness to volatile conditions.
