Thailand's Stock Exchange is reforming trading regulations with approval from its board and now awaits SEC sign-off (expected September–October 2026). Key changes include revised Uptick Rule for short selling, elimination of Dynamic Price Bands, new registration requirements for High-Frequency Trading (HFT), and removal of Minimum Resting Time restrictions. The exchange reports improved trading behavior after recent supervisory process updates that now share risk-flagged activity with all brokers rather than isolated warnings.
