==== Auction Mechanisms ====

=== Open ===

The opening auction occurs at 8:50. The mechanism is similar to the closing auction which follows call, price determination, and order execution phases.

=== Close ===

The closing price is defined by the following closing mechanism.

**Auction** means an auction conducted in a trading platform with respect to qualifying orders pursuant to the following process:

  * a) Call Phase: all orders to be executed during the closing auction participate in the price determination, irrespective of time or size
  * b) Price determination occurs with all executable orders established during the call phase of the closing auction
  * c) All non-executed or partially executed market, limit, and market-to-limit orders with a limit assigned are transferred to the next trading day according to their validity
  * d) The closing auction price cannot be determined if there are no executable orders, in which case the best bid/ask limit is published
