Globex Opening

Prior to the opening of each Globex session, Globex will provide an indicative price or prices, based on the Globex equilibrium price algorithm as follows, and on all pending orders that may be executed on the opening.

During the 30-second period prior to the opening, no previously entered orders may be modified or cancelled, though new orders may be entered. Globex will establish an equilibrium price that will be the opening price. The equilibrium price is the calculated price between sell pressure and buy pressure where the largest volume of trading can occur. The equilibrium price is one of the following:

  • a) The price within the equilibrium that has the largest trade volume and the lowest unmatched volume at that price remaining after the opening; or

  • b) If more than one price has the same trade volume and the same unmatched volume at that price, the equilibrium price is the one nearest the previous day's settlement price.

Bids and Offers will be selected for matching at the opening price based on price-time priority.
