The Australian Securities Exchange (ASX) is one of the world's leading financial markets, operating a fully electronic order book system. Understanding its operating hours is crucial for investors and traders to plan their activities effectively. So, what time does the Australian stock market close?

The ASX has a well-defined schedule for its trading sessions. However, it's essential to note that the market's closing time can vary slightly depending on the specific session and whether it's a business day or not.

ASX Trading Sessions
The ASX operates two primary trading sessions: the Cash Market and the Derivatives Market. Each has its unique opening and closing times.

Before diving into the closing times, let's briefly understand the opening hours of these sessions:
Cash Market

The Cash Market, where equities, ETFs, and other securities are traded, opens at 10:00 AM (Sydney time) and closes at 4:00 PM on business days. However, there's a brief pause in trading between 4:00 PM and 4:05 PM for the closing auction.
On quarterly and semi-annual index review dates, the Cash Market opens at 9:50 AM and closes at 4:05 PM, with no pause for the closing auction.
Derivatives Market

The Derivatives Market, which deals in futures and options, opens at 9:50 AM and closes at 5:00 PM on business days. Similar to the Cash Market, there's a brief pause in trading between 4:55 PM and 5:00 PM for the closing auction.
On quarterly and semi-annual index review dates, the Derivatives Market opens at 9:50 AM and closes at 5:05 PM, with no pause for the closing auction.
Non-Business Days and Special Trading Sessions

The ASX is closed on weekends and public holidays. However, it occasionally operates special trading sessions, such as Good Friday, Christmas Day, and Boxing Day, with adjusted opening and closing times.
It's crucial to stay updated with the ASX's official website or consult a reliable financial news source to confirm the operating hours during these special sessions.



















After-Hours Trading
While the ASX's primary trading sessions close in the late afternoon, there's an after-hours trading session called the ASX Trade24. This session operates from 7:00 PM to 7:05 PM on business days, allowing investors to trade select securities outside regular market hours.
However, it's essential to note that not all securities are eligible for trading during the ASX Trade24 session, and the available securities may change from time to time.
In summary, the Australian stock market closes at 4:00 PM for the Cash Market and 5:00 PM for the Derivatives Market on regular business days. However, it's always a good idea to confirm the operating hours, especially during special trading sessions or index review dates. Stay informed and make the most of your trading opportunities in the dynamic world of the ASX.
