The Korea Exchange (KRX) has moved to counter controversy over extending trading hours, saying the claims differ from the facts. The exchange outlined its position on five issues tied to the planned launch of a pre- and after-market on June 29. It said member firms will apply internal monitoring systems as in regular trading, and the exchange will conduct market surveillance at the same level as alternative venue NXT. It also pledged guidance on system changes and said phone orders via call centres will be allowed to limit exclusion of older investors.

South Korea’s first alternative trading system NextTrade has expanded rapidly since its March debut, drawing praise at a symposium hosted by the Korea Securities Association. Participants said the multiple‑market regime has taken hold but called for easing the 15 percent market share cap, expanding tradable assets and upgrading related systems. They also noted positive effects such as extended trading hours and lower fees, while urging safeguards and clearer rules to address liquidity, surveillance and stability concerns.
