Bangkok: The Stock Exchange of Thailand (SET) will implement Auto Pause for each security on May 6, suspending trading for 60 minutes, not exceeding one time per day, to allow investors more time to review and manage purchase or sell orders than usual, raising the level of supervision of securities trading.
According to Thai News Agency, the Stock Exchange of Thailand will start implementing the Auto Pause measure for each security, which is part of a plan being gradually introduced in 2024. The main objective of this measure is to allow securities companies and investors time to examine and manage purchase or sale orders by placing the Pause (P) mark on securities with higher than normal purchase or sale orders. This will help prevent abnormal trading pairing and reduce risks to investors.
The guidelines for using the Auto Pause measure specify that trading will be automatically stopped for 60 minutes if any security's buy or sell orders exceed 15% of the total number of registered securities. This involves marking the security with a Pause (P) for 40 minutes followed by a Pre-Open for 20 minutes before resuming normal trading. The Auto Pause can only be activated once per day for each security and applies to common stocks, REITs, property funds, and infrastructure funds. When a security is Auto Paused, related securities like warrants, DWs, and single stock futures are also suspended from trading. However, the measure will not apply to securities with inherently high trading volumes, such as those newly listed or temporarily reopened for trading.
During the P marking period, investors can still edit or cancel trading orders. The Auto Pause measure will be effective from May 6, 2025, onwards. Investors and interested parties can find more information about the revised criteria on the Stock Exchange of Thailand website under 'Rules/Supervision' and 'Rules and Circulars Relating to Securities Trading.'
