A buy-side sidecar, which temporarily suspends the validity of program trading buy orders, was triggered on Oct. 27 as the KOSPI surged.


According to the Korea Exchange (KRX), program trading buy orders on the KOSPI market were suspended for five minutes at 10:13 a.m.


A buy-side sidecar on the KOSPI is triggered when KOSPI 200 futures prices rise by 5% or more from the previous day and remain at that level for one minute.


As of 10:30 a.m., the KOSPI was trading at 5,716.83, up 4.58% from the previous trading session.
