What is CFD trading?
Written by an ex-institutional trader. A plain-English explanation of CFD trading: what a contract for difference is, how it works (shown with a diagram), how leverage and going short work, what it costs, and how it is regulated in Australia.
Direct answer
CFD trading means trading a contract for difference: an agreement to exchange the difference in an asset's price between when you open and close the trade, without ever owning the asset itself. If the price moves your way you receive the difference; if it moves against you, you pay it. CFDs let you trade forex, shares, indices, commodities and crypto from one account, using leverage, and to profit from falling prices as easily as rising ones.
Because you never own the underlying asset, CFDs are flexible but carry real risk. Leverage magnifies both gains and losses, and in Australia ASIC-mandated disclosures show 70 to 85 percent of retail CFD accounts lose money. CFD trading is fully legal here through ASIC-regulated brokers, with protections including leverage caps, negative balance protection and segregated funds. It is a powerful tool, not easy money.
What CFD trading is
CFD trading means trading a contract for difference: an agreement between you and a broker to exchange the difference in an asset's price between the moment you open the trade and the moment you close it, without ever owning the asset. The CFD simply tracks the price of something real, a share, a currency pair, an index, a commodity or a cryptocurrency, and settles the price change in cash.
That one feature, no ownership, is what makes CFDs so flexible. Because you are trading the price rather than the thing itself, you can use leverage, profit from falling prices, and trade markets all over the world from a single account. It is also what makes them risky, because leverage cuts both ways.

How a CFD works
Say a share trades at A$100 and you expect it to rise. You open a buy (long) CFD at A$100. The position tracks the share price exactly. If the share rises to A$110 and you close, your profit is the A$10 difference for each unit you traded. You never owned the share; the broker simply pays you the price difference in cash.
The same works in reverse for a short. If you expected the share to fall, you would open a sell (short) CFD at A$100, and if it dropped to A$90 you would collect the A$10 difference. Your profit or loss is always the gap between the open and close price, multiplied by how many units you traded.
Leverage and going short
Two features define CFD trading and separate it from simply buying an asset.
- Leverage. You only put up a fraction of the position's value, called margin, and the broker funds the rest. A 20:1 leverage means a A$500 deposit controls a A$10,000 position. This magnifies your profit and your loss relative to the cash you put up, which is the single biggest reason CFD accounts can blow up quickly. See what is leverage for the full picture.
- Going short. Because you never own the asset, selling first to profit from a falling price is as simple as buying. This lets CFD traders make money in down markets and hedge existing holdings, something that is awkward or impossible when you own the asset outright.
These features make CFDs powerful for short-term trading and hedging. They also make them genuinely dangerous in inexperienced hands, because the same leverage that promises large gains delivers large losses just as readily.
What you can trade as a CFD
One of the main draws of CFD trading is breadth: a single account gives you access to markets that would otherwise need several. The common CFD markets are:
- Forex, the currency pairs, the most traded CFD market. See what is forex trading.
- Indices, such as the ASX 200 or S&P 500, tracking a whole market in one position.
- Shares, individual companies, long or short, with leverage.
- Commodities, including gold, silver, oil and natural gas.
- Cryptocurrencies, as crypto CFDs, capped at 2:1 leverage under ASIC.
Each asset class has its own ASIC leverage cap, covered in the CFD trading in Australia guide.
CFDs vs owning the asset
The clearest way to understand a CFD is to compare it with owning the real thing.
| Feature | CFD | Owning the asset |
|---|---|---|
| Ownership | No, price exposure only | Yes, you hold the asset |
| Leverage | Yes, a fraction as margin | No, pay the full value |
| Go short | Yes, easily | Rarely or not at all |
| Income | Cash adjustment for dividends | Dividends, interest, rights |
| Overnight cost | Financing charge to hold | None |
| Best for | Short-term trading, hedging | Long-term investing |
| Australian tax | Profits taxed as ordinary income | Capital gains, 50% discount if held 12+ months |
The takeaway: CFDs are built for active, short-term trading and shorting, while owning the asset suits long-term investing. Neither is better in the abstract; they suit different goals. For buy-and-hold, the leverage and overnight costs of a CFD work against you.
What CFDs cost
CFD costs come in three parts:
- Spread, the gap between the buy and sell price, your main cost on every trade. See what is the spread.
- Commission, charged on raw-spread share CFDs in exchange for tighter spreads.
- Overnight financing (swap), a daily charge for holding a leveraged position open overnight. Day traders who close intraday avoid it; longer holds pay it. See what is swap.
For a short-term trade the spread dominates; for a position held weeks, financing can become the largest cost. The total cost of trading calculator adds them up for a given trade.
CFD trading in Australia
CFD trading is fully legal and well-regulated in Australia. Brokers must hold an Australian Financial Services Licence from ASIC, and ASIC imposes leverage caps (30:1 on major forex pairs, 20:1 on minor pairs, gold and major indices, 10:1 on other commodities and minor indices, 5:1 on shares and 2:1 on crypto), negative balance protection, segregated client funds and AFCA dispute access.
The honest part belongs here too. ASIC requires brokers to publish the share of retail accounts that lose money, and those figures sit consistently in the 70 to 85 percent range. CFDs are a legitimate, regulated instrument, but the marketing that frames them as easy money is the opposite of the truth. Profits are also taxed as ordinary income rather than under capital gains, because you never hold an underlying asset, covered in the forex and CFD tax guide.
How to start
A sensible order if you want to learn CFD trading properly:
- Learn the fundamentals. Understand leverage, margin, spread and swap before risking money. The forex glossary defines every term.
- Practise on a demo account. Trade with virtual money to learn the platform at no risk.
- Choose an ASIC-regulated broker. Verify the licence and compare cost on the best CFD brokers in Australia ranking.
- Start small and manage risk. Risk a small fixed percentage per trade, sized with the position size calculator, and only use money you can afford to lose.

Frequently asked questions
What is CFD trading in simple terms?
CFD trading is making an agreement with a broker to exchange the difference in an asset's price between opening and closing a trade, without owning the asset. A CFD, or contract for difference, tracks the price of something like a share, currency pair or commodity. If the price moves in your favour, the broker pays you the difference; if it moves against you, you pay. It lets you speculate on price moves up or down, with leverage, across many markets from one account.
How does CFD trading work?
You open a CFD position by buying (going long) if you expect the price to rise, or selling (going short) if you expect it to fall. The position tracks the underlying price tick for tick. When you close it, your profit or loss is the difference between the open and close price, multiplied by your position size. Because CFDs are leveraged, you only put up a fraction of the position's value as margin, which magnifies both the profit and the loss relative to that deposit.
Is CFD trading the same as forex trading?
They overlap but are not identical. Forex is one market, the exchange rate between currencies. CFDs are the instrument most retail traders use to trade forex, alongside shares, indices, commodities and crypto. So retail forex trading in Australia is almost always done as CFDs, which is why the terms are often used interchangeably. Put simply, forex is one of the things you can trade with a CFD; a CFD is the wrapper that lets you trade forex and much else with leverage.
Is CFD trading legal in Australia?
Yes. CFD trading is fully legal for Australian residents through brokers holding an Australian Financial Services Licence from ASIC. ASIC regulates the market with consumer protections including leverage caps (30:1 on major forex pairs, lower on other assets), negative balance protection so you cannot lose more than your balance, segregated client funds, and AFCA dispute resolution. Trading through unlicensed offshore brokers is not illegal for you, but none of those protections apply, so it is strongly inadvisable.
What is the difference between a CFD and buying shares?
When you buy a share you own a piece of the company, can hold it indefinitely, and receive dividends and voting rights. A share CFD gives you price exposure without ownership: no voting rights, a cash adjustment in place of dividends, and an overnight financing charge for holding with leverage. CFDs let you use leverage and short easily and are taxed as income rather than under capital gains, but they are built for shorter-term trading, not long-term investing. For buy-and-hold, owning the share is usually better.
Why do most CFD traders lose money?
ASIC-mandated disclosures show 70 to 85 percent of retail CFD accounts lose money, mainly because leverage magnifies losses, short-term price movement is hard to predict, and costs accumulate on frequent trading. Leverage that turns a small deposit into a large position also turns a small adverse move into a large loss, and beginners often over-leverage and under-manage risk. CFDs are a legitimate tool, but the combination of leverage and active trading is unforgiving, which is why risk management matters more than any entry signal.
