A report from the Stock Exchange of Thailand (SET) indicates that starting May 6, 2025, the Thai stock market will implement the Auto Pause Measure for individual securities. This aims to give brokerage firms and investors time to verify and manage buy or sell orders by marking securities with a Pause (P) indicator.
This is intended for securities with buying or selling orders that are higher than normal, helping to prevent abnormal trading matching and to reduce risks for investors.
For implementing the Auto Pause Measure, trading will automatically be paused for 60 minutes when any security’s total buy or sell order volume across all price levels exceeds 15% of its registered shares. It will be marked with a Pause (P) for 40 minutes and then pre-open for 20 minutes before resuming normal trading.
The Auto Pause Measure will be applied no more than once a day per security and will apply to common stocks, REITs, Property Funds, and Infrastructure Funds. When a security is paused, any financial products using it as a reference asset, such as Warrants, Derivative Warrants (DW), and Single Stock Futures, will also be paused.
“Exceptions to the Auto Pause Measure will be made for securities with the potential to cause unusually high trading volumes. These include newly listed securities on their first trading day, securities temporarily reintroduced before being suspended for a long time or before being delisted. During the P-marked period, investors can still modify or cancel their trading orders,” the SET stated.
