How orders match

During the 09:08-09:12 matching window:

  1. Exchange aggregates all orders received.
  2. Computes the indicative opening price that maximises matched volume.
  3. Matchable orders execute at the opening price.
  4. Unmatched orders carry over to the continuous session.

Tips for retail traders

  • Limit orders preferred for predictable execution.
  • Market orders may execute at the indicative open (which can swing).
  • Watch the indicative price during 09:08-09:15 to gauge overnight sentiment.
