ASX trading questions, answered simply.

Written for people new to the ASX. Skim the list, jump to what you need, come back when you’re stuck.

01

Day trading rules in Australia - is there a pattern day trader rule?

No US-style Pattern Day Trader rule from ASIC.

On the ASX you can buy and sell the same share on the same day. ASIC does not run a US-style “3 day trades in 5 days” frequency rule for retail share trading.

Your broker can still set its own limits in its terms. Always check those before you trade size or frequency.

02

How do the ASX pre-open and opening auction work?

Orders build from 7:00am. Around 9:59am one auction sets every stock's open price, then continuous trading starts.

From 7:00am Sydney the market is in pre-open. You (via your broker) can enter, amend or cancel orders. Nothing matches yet - the book just fills up.

Around 9:59am the Opening Single Price Auction (OSPA) runs. Overlapping buys and sells are matched at one single price chosen to maximise matched volume. That price is the stock's open for the day.

During the auction itself you cannot enter or amend orders. You can cancel existing ones. Permitted trade reports can still be lodged. After a short buffer, continuous matching starts (earliest about 9:59:45am).

The two thin striped bands are random 15-second windows. ASX picks the exact switch time inside each window so nobody can game the millisecond the auction or the open begins.

Since 23 June 2025 this applies to all ASX cash equities together - the old A-Z staggered open (roughly 10:00 to 10:09) is gone. Times are Sydney. The close has its own auction later - see closing auction.

ASX trading hours across Australian cities

The ASX clock is Sydney time. Other cities shift with the time zones and daylight saving.

Normal trading is about 9:59:45am–4:00pm Sydney. Pre-open starts 7:00am Sydney. During daylight saving (roughly early Oct–early Apr), Sydney/Melbourne/Hobart move one hour ahead of Brisbane, Adelaide and Perth stay offset.

04

ATO: trader vs investor for tax

The ATO looks at how you actually trade - not what you call yourself.

Investors usually deal with capital gains tax. Traders may be treated as a business (ordinary income and deductions). Volume, regularity, and a business-like setup all matter. This is general info only - not tax advice.

05

Choosing a broker for ASX investing

Pick on criteria - not a brand list.

  • CHESS-sponsored vs custodial: do you get a HIN in your name?
  • Brokerage: cost per trade at the size you actually hold and trade.
  • Level 2 / market depth: can you see more than the best bid and ask?
  • Order types: limit, market, stop - what you need day to day.
  • Shares vs CFDs: this section is about holding shares. CFDs are a different product (see the next question).

We don't rank brokers here. Compare those points yourself.

06

Choosing a platform for ASX day trading

Many ASX day traders use share CFD platforms such as FP Markets.

These are share CFDs, not owning the shares - so no CHESS HIN. You can usually go long or short. ASIC's product intervention order caps retail leverage on share CFDs at 5:1 (20% initial margin). Eligible wholesale / sophisticated clients (Corporations Act tests that include s708(8) and s761G) can access higher leverage - FP Markets lists share CFDs at up to 1:20 for pro accounts.

CFDs are leveraged and high risk. ASIC reported that in 2023-24, 68% of retail clients who traded CFDs made a net loss. Check the provider's disclosure before you open anything.

07

Which trading platform do ASX day traders use?

Mottai is a purpose-built ASX day-trading platform offered through FP Markets.

Mottai is aimed at fast order entry, Level 2 depth, and DMA share CFDs on the ASX. FP Markets offers it alongside other platforms such as Iress for ASX CFD trading. Mottai's own FP Markets page is the place to check features and costs.

09

ASX trading Discord - what is the Demoniaco room?

A chat of 2,500+ Australian traders. Joined via Patreon. Not a signals service.

  • Join through Patreon, then connect Discord.
  • Voice usually runs about 9:45am–11:00am Sydney on market days.
  • Best if you already have a few months of active trading. Brand new? Start with the course.

People share what they’re watching. It isn’t stock picks or a tip line.

10

How much money to start day trading?

Enough that fees and one bad day don’t wipe you - and only money you can afford to lose.

Brokerage on small trades eats returns. So does oversizing. There’s no magic number and no promised outcome. Start small, learn the exchange, and treat the first months as tuition you might never get back.

If you can't make money on a $5,000 account, then you can't make money on a $50,000 account. So don't rush trying to be profitable. Work on finding where your edge in the market lies.

11

What is ASX Level 2 / market depth?

Level 1 shows the best buy and sell. Level 2 shows the queue behind them.

“Market depth” is that queue of bids and asks at each price. Day traders often want it for thin stocks. You don’t need it on day one - many beginners start on Level 1 and add depth later.

12

How does the ASX closing auction work?

Continuous trading stops at 4:00pm. A short auction sets the official close.

  • 4:00–4:10pm Sydney: pre-close - orders can still be entered or changed; no continuous matching.
  • ~4:10–4:11pm: Closing Single Price Auction (randomised start). That price is the day’s close.

Exact windows are on the ASX trading-hours page for the close and the opening auction.

13

Can you short sell ASX shares as a retail trader?

Shorting real ASX shares is limited for most retail accounts. CFDs are a different product.

ASX rules allow short sales of approved products by market participants, with reporting. Many retail share brokers simply don’t offer shorting of shares. CFDs can go short, but MoneySmart treats them as high-risk leveraged products. FP Markets is one of the most commonly used brokers by ASX day traders.

14

What is CHESS / CHESS-sponsored / HIN vs custodial?

CHESS-sponsored usually means the shares sit in your name under a HIN.

  • CHESS-sponsored: broker sponsors you; you get a Holder Identification Number (HIN); legal title is in your name; easier to move brokers.
  • Custodial / nominee: the custodian holds the shares for you - common on some apps. Check your broker’s docs for which model you get.

T+2 settlement explained

Trades settle two business days later. You can often trade again sooner - settled cash is different.

ASX equity trades settle on T+2 (trade day + two business days): shares and money change hands then. Brokers may still let you buy or sell before settlement settles - but “settled funds” for withdrawal or some sells can wait until T+2. Ask your broker how their cash works.

You can often place another trade before T+2. Settled cash for withdrawal is usually after settlement - confirm with your broker.

16

Trading halts, pauses and suspensions

A halt freezes trading for a bit. Your orders usually stay queued - a suspension is heavier.

  • Trading halt: no matching while it’s on. Orders can often sit, be amended, or cancelled. ASX does not auto-purge them (your broker still might).
  • Suspension: longer stop. Orders are typically purged.

When news hits, expect the stock to reopen jumpy. Check the announcement before you re-enter.

17

ASX swing trading vs day trading

Same exchange. Different clock.

  • Day: in and out inside the cash session. No overnight gap - but the open and close move fast.
  • Swing: held days or a few weeks. You take overnight and weekend risk.

Neither is a shortcut. The beginners course covers foundations for both.

Holding time, not “better” or “safer”

18

Limit order vs market order on the ASX

A limit sets your price. A market order aims to trade now at the going price.

  • Limit: you set the most you will pay (buy) or the least you will accept (sell). It only trades at that price or better. It may not fill straight away.
  • Market / market-to-limit: you want a fill now at the best available opposing price. On ASX Trade, a market order that does not fill fully typically rests as a limit at that price.

Thin stocks and fast markets can fill at a worse price than you glanced at. Your broker's labels can differ - check their order ticket help.

19

Can you trade ASX shares after hours?

There is no US-style retail after-hours session on the ASX cash market.

Normal continuous trading on ASX cash equities runs through the day session (from the open until 4:00pm Sydney), then the closing auction. After that, later session states are for closing administration - not a liquid retail night market like in the US.

Many brokers still let you enter limit orders outside hours. Those sit until the next pre-open / trading day. Market-style orders are usually only accepted in normal trading.

Always check your broker's rules for out-of-hours order entry.

20

What is the bid-ask spread?

The gap between the best buy price and the best sell price.

The bid is the best price buyers are willing to pay. The ask (offer) is the best price sellers will take. The difference is the spread.

If you buy at the ask and later sell at the bid, you have crossed the spread both ways - that cost sits on top of brokerage. Busy large stocks usually show tighter spreads than quiet small ones.

21

What is DMA (direct market access) on the ASX?

Your orders go to the exchange through a broker's automated systems - not keyed by a person each time.

On the ASX, direct market access (DMA) means a market participant gives clients a way to submit orders that pass through the participant's internal systems and risk controls, then onto the trading platform - without a desk person re-typing every order.

ASIC describes the same idea under automated client order processing (also called direct electronic access). Filters and controls still sit with the participant. DMA is about how orders reach the market, not a recommendation of any broker or platform.

Some ASX day-trading platforms advertise DMA-style access for share CFDs or cash equities - that is separate from whether DMA suits you. See the earlier broker / platform questions.

Sources: ASX glossary: direct market access (DMA) · ASIC RG 241 Electronic trading (PDF)

22

Can you day trade in an SMSF?

Possible in limited cases - but the ATO sole purpose test and advice still come first.

SMSFs can invest in listed shares, but every investment decision must meet the sole purpose test: the fund is maintained to provide retirement (or death) benefits - not present-day personal benefits.

High-turnover day trading can look like carrying on a business inside the fund. That is not automatically banned, but it must be allowed by the trust deed, fit the documented investment strategy, and still satisfy the sole purpose test. The ATO pays close attention when activity looks like a hobby, pays related parties, or delivers personal benefits.

This is general education only - not tax or SMSF advice. Speak with a licensed adviser before you trade inside an SMSF.

23

When is the ASX closed for public holidays?

The cash market closes on listed national public holidays - check the ASX trading calendar.

The ASX cash market does not trade on weekends or on the public holidays published in the ASX trading calendar. Settlement calendars can differ slightly from trading days, and some early closes apply around year-end.

Holiday dates change each year. Use the official calendar rather than a copied list that can go stale.
