10am - 4pm
Normal Trading
Orders are placed immediately into the market and transact as soon as volume is available at the specified price level.
4pm - 4:10pm
Pre-CSPA ("Match")
You can place, remove, or amend an order, but no trades actually take place.
Orders (both buy and sell) are ranked according to their price. Who ever bids the highest (for buyers) or offers the lowest (for sellers) is placed at the front of the queue.
Often there is a crossover in the middle (e.g. the lowest seller might offer $1.55 and the highest buyer might bid $1.63).
The area in the middle where they cross over is called the “match”.
4:10pm - 4:12pm
ASX Close (Closing Single Price Auction)
A random time for the close is generated by the ASX between 4:10 - 4:12 p.m. AEST.
"Matching” share prices are weighted to find their mid-point and this becomes the closing price of the share. All trades that take place on the close transact at the same price regardless of what price an investor bids or offers.
4:12pm - 6:50pm
Adjust
Trading has stopped for the day. New trades cannot be entered into the system but stockbrokers can change or remove existing orders.
6:50pm - 6:59pm
Purge Orders
Orders that are too far from the market or have expired are removed from the market.
6:59pm - 7pm
System Maintenance
For administration purposes.
7pm - 7am
Closed
The system is closed. The database is updated with securities being added and removed.
