The ASX (Australian Securities Exchange) operates between 10:00am and 4:00pm AEST on business days, Monday to Friday. However, trading does not simply switch on and off at these times — there are pre-open, opening, continuous trading, and closing phases that affect how orders are executed. Here is a complete guide to ASX trading hours in 2026.
Core ASX Trading Hours
All times are in AEST (Australian Eastern Standard Time) — UTC+10. During daylight saving time in NSW/VIC (October to April), AEST becomes AEDT (UTC+11), but ASX hours remain the same clock time.
| Phase | Time (AEST) | What happens |
|---|---|---|
| Pre-open (opening auction) | 7:00am – 10:00am | Orders can be placed but not executed; system calculates opening prices |
| Opening | 10:00am – 10:02am | Opening auction runs, prices set, orders matched (staggered by stock group) |
| Continuous trading | 10:02am – 4:00pm | Orders matched in real time as buy and sell orders arrive |
| Pre-close (closing auction) | 4:00pm – 4:10pm | Orders queued for the closing price calculation |
| Closing auction | 4:10pm – 4:12pm | Closing prices set for all securities |
| After-close trading | 4:12pm – 5:00pm | On-market trades at the closing price only |
Staggered Opening Times
Not all 2,000+ ASX-listed securities open simultaneously at 10:00am. To prevent technical overload, the opening auction is staggered across alphabetical groups:
| Security group | Opening time (approx.) |
|---|---|
| A–B tickers | 10:00:00am |
| C–F tickers | 10:00:01am |
| G–M tickers | 10:00:02am |
| N–R tickers | 10:00:03am |
| S–Z tickers | 10:00:04am |
The difference is only seconds and is irrelevant for most investors. It matters primarily for algorithmic and high-frequency traders.
What to Do If You Place an Order Outside Trading Hours
If you place a buy or sell order when the ASX is closed (overnight, weekends, or public holidays):
- The order is queued and enters the pre-open session the next trading day
- Market orders placed outside hours may execute at unexpected prices if the market opens significantly higher or lower
- Limit orders offer better control — they only execute at or better than your specified price
For most retail investors, placing a limit order for peace of mind when investing outside trading hours is preferable to a market order.
ASX Market Holidays 2026
The ASX is closed on national and state-based public holidays. Note that NSW and VIC public holidays affect the Sydney-based ASX. State holidays in other states do not close the ASX (the ASX is based in Sydney).
ASX closure dates in 2026 (confirmed and expected):
| Date | Holiday |
|---|---|
| 1 January 2026 | New Year’s Day |
| 26 January 2026 | Australia Day |
| 3 April 2026 | Good Friday |
| 6 April 2026 | Easter Monday |
| 25 April 2026 | Anzac Day |
| 8 June 2026 | King’s Birthday (NSW/VIC) |
| 25 December 2026 | Christmas Day |
| 28 December 2026 | Boxing Day (observed Monday) |
Check the ASX website (asx.com.au) for the definitive list as dates can vary by year.
Time Zone Conversions
Australian investors in other states trade on AEST regardless of their local time:
| State | Standard time offset | ASX opens (local) | ASX closes (local) |
|---|---|---|---|
| NSW / VIC / ACT / TAS | AEST (UTC+10) | 10:00am | 4:00pm |
| QLD | AEST (UTC+10) | 10:00am | 4:00pm |
| SA | ACST (UTC+9:30) | 9:30am | 3:30pm |
| WA | AWST (UTC+8) | 8:00am | 2:00pm |
| NT | ACST (UTC+9:30) | 9:30am | 3:30pm |
Daylight saving: NSW/VIC/SA shift forward one hour in summer — adjust local open/close times accordingly.

Frequently Asked Questions
Can I buy shares after 4pm on the ASX? You can place orders after 4:00pm, but continuous trading stops at 4:00pm. From 4:00–4:10pm is the pre-close phase. From 4:10–4:12pm the closing auction sets the official closing price. After-close trading from 4:12–5:00pm allows trades at the closing price. Orders placed after 5:00pm are queued for the next trading day.
Does the ASX close on state public holidays? The ASX follows NSW public holidays (as it is Sydney-based). State public holidays in other states (e.g., Melbourne Cup Day in VIC, Adelaide Cup in SA) do not close the ASX. Queen’s/King’s Birthday dates vary by state — check the ASX website for the specific NSW/ACT date.
What is the best time of day to buy shares on the ASX? For long-term investors, the time of day matters very little. However, the first 15–30 minutes after open and last 15–30 minutes before close tend to have higher volatility and wider bid/ask spreads as large institutional trades are placed. Mid-morning (10:30am–12:00pm) is often considered a more stable period with tight spreads on liquid securities.
