What is an At-auction Limit Order?

An At-auction Limit Order is an order with a specified price. An At-auction Limit Order will be matched in price and time priority at the final Indicative Equilibrium Price (IEP). At-auction Limit Orders will not be matched at a price worse than the final IEP.

When the market opens, any outstanding At-auction limit orders will be carried forward to the Continuous Trading Session and treated as limit orders provided that the specified price of that At-auction limit order does not deviate 9 times or more from the nominal price.
