Circuit Breaker

Circuit Breaker

In order to control volatility of the market and to give investors an opportunity to better consider information during periods of panic buying and selling, the SET will temporarily stop during the trading session.

The circuit breaker functions as follows:

  • If the SET Index falls by 10% from the previous day's close, all trading in listed securities will be halted for 30 minutes.
  • If the SET Index falls another 10% (to 20% from the previous day's close), trading in all listed securities will be halted for one hour.
  • If trading time left in a session is less than 30 minutes, or one hour after the circuit breaker comes into effect, trading will be halted until the closing time of that session, and will then resume in the next session.
