[South Korean Trading Platform Triggers KOSPI Index Sidecar Mechanism, Programmatic Trading Paused for 5 Minutes] BlockBeats News, July 20: The South Korean trading platform (KRX) triggered the sidecar mechanism due to fluctuations in the KOSPI index, resulting in a suspension of programmatic trading for approximately 5 minutes. The sidecar mechanism is primarily used to address sharp fluctuations within a short period and only restricts programmatic trading, while manual trading can still proceed as usual. Unlike the circuit breaker mechanism, the sidecar mechanism does not halt the entire market but is more akin to a 'speed bump' during periods of market volatility. In contrast, the circuit breaker mechanism is typically employed during extreme market conditions, and once triggered, it halts all market trading to prevent further escalation of panic-driven fluctuations.
