The evidence strongly supports the truthfulness of the statement. The most authoritative sources, two direct reports from the top-tier news agency Reuters, confirm that the Korea Exchange activated a 'sidecar' trading curb on the KOSPI. A sidecar is a specific market mechanism that, by definition, temporarily halts program trading to curb market volatility. This action is functionally identical to suspending program trading orders.This core fact is corroborated by multiple other sources. Credible news organizations, including The Jakarta Post and The Star Business, explicitly reported that South Korea halted program trading sell orders. While these reports were on social media platforms, they originate from established news outlets. Further mentions from financial commentary accounts and other wire service reports on social media are all consistent with this event, even specifying the duration of the halt (5 minutes) and the trigger (a sharp drop in KOSPI 200 futures).There is no conflicting evidence among the provided sources; all relevant information points to the same conclusion. The only irrelevant source is the website for the Stock Exchange of Thailand, which contains no information on the matter. The consistency across multiple sources, led by highly authoritative primary reports from Reuters, provides high confidence that South Korea did indeed suspend program trading.
