SET adds Auction Matching, Dynamic Price Band, and Minimum Resting Time measures from September 2, 2024 to build investor confidence The Stock Exchange of Thailand (SET) is moving forward with improving 3 regulatory measures in addition to the previously implemented short selling and trading program regulatory measures to build investor confidence. They will be effective from September 2, 2024 onwards, as summarized below: 1. Intensify the regulatory measures for securities trading that are traded abnormally (the 'Measures') from the current measures by adding a one-time matching method (Auction) according to the time period specified by the Stock Exchange of Thailand for securities that are traded abnormally and that the Stock Exchange of Thailand has specified to be in the Measures from Level 2 and above. 2. Set the Dynamic Price Band trading price range for each security (±10% from the latest trading price of that security) in addition to the current Ceiling and Floor (±30% from the closing price on th e previous business day) to increase the mechanism to control the volatility of securities trading prices. 3. Set the minimum time for trading orders. Before being able to edit or cancel a trading order (Minimum Resting Time), the trading order must remain in the system for at least 250 milliseconds before being able to edit or cancel the order. This is to slow down and prevent the occurrence of trading orders in the form of insert-withdrawal that are too frequent, which may cause investors to misunderstand that there is a need to buy or sell securities in large quantities.
