    • 2. Characteristics of a suspension and a trading halt

      Characteristic Suspension Trading Halt
      Initiating party A suspension can be imposed by SGX-ST under the circumstances stated in Rule 8.13.1. An Issuer may also request a suspension if its request for extension of a trading halt is not approved by SGX-ST. A trading halt can be imposed by SGX-ST under the circumstances stated in Rules 8.15.1 and 8.15.2.
      Status of unmatched orders During a market suspension, unmatched orders in the Trading System may lapse, as determined by SGX-ST. SGX-ST will notify Trading Members of the status of their unmatched orders before the lifting of a market suspension.

      During a suspension of a single security or futures contract, all unmatched orders will lapse.
      During a trading halt, all existing orders in the Trading System remain valid. Orders can still be entered, modified or withdrawn but will not be matched.
      Duration of suspension or trading halt A suspension may persist for a prolonged period. A trading halt is usually intra-day, with a minimum duration of 30 minutes. SGX-ST may extend the duration of a trading halt beyond three Market Days upon the Issuer's request.
      Upon lifting of suspension or trading halt Upon lifting of a suspension, the suspended security or futures contract will enter into an Adjust Phase for at least 15 minutes. Upon lifting of a trading halt, orders that can be matched will be matched at a single price computed based on the algorithm set by SGX-ST. Unmatched orders will be carried forward into the market phase that the market is in when the trading halt is lifted.
