The Stock Exchange of Thailand is moving forward with the improvement of 3 additional regulatory measures in addition to the previously implemented short selling and trading program regulatory measures to build investor confidence, effective from September 2, 2024 onwards, as summarized below.
The Stock Exchange of Thailand (SET) has announced three additional regulatory measures to enhance market supervision and boost investor confidence, following recent amendments to short selling and program trading regulations. The new measures, effective September 2, 2024, are as follows:
1. Auction Matching Method will be required for all investors trading securities that SET has designated as the trading surveillance measures at Level 2 and above, in addition to the existing measures for securities with abnormal trading conditions.
2. Dynamic Price Band for individual securities of ±10 percent from the latest execution price will be imposed. This measure will complement the existing daily ceiling and floor price limits of ±30 percent from the previous day’s closing price, providing an additional mechanism to mitigate securities price fluctuation.
3. Minimum Resting Time before an order can be amended or cancelled is set at 250 milliseconds. This measure aims to curb excessively frequent order updates and cancellations that could potentially mislead the market about high demand for particular securities.
