When does the ASX open and close?

Standard Trading Hours

The Australian Securities Exchange (ASX) is open for trading from Monday to Friday, excluding public holidays. The regular trading hours are from 10:00 AM to 4:00 PM Australian Eastern Standard Time (AEST). These hours represent the core period during which securities transactions can occur on the exchange.

Pre-Open and Post-Close Sessions

Before the official market opens, the ASX has a pre-open session starting at 7:00 AM. During this time, investors can enter, amend or cancel orders, but no trades are executed until the market opens at 10:00 AM. After the market closes at 4:00 PM, the ASX allows for a post-trading session until 7:00 PM where investors can continue to enter orders, but these will be queued for the next trading day.

Impact of Public Holidays

The ASX does not operate on public holidays. These include national holidays such as Christmas Day, Boxing Day, New Year's Day, and Australia Day, among others. On these days, the trading schedule is adjusted, and no transactions are processed. It is important for investors to be aware of these dates to manage their trading activities effectively.

Daylight Saving Time Adjustments

It is important to note that the ASX operates on Australian Eastern Standard Time (AEST) but shifts to Australian Eastern Daylight Time (AEDT) during daylight saving months. This shift typically occurs from the first Sunday in October to the first Sunday in April, affecting the time difference for international traders.
