CFD Trading
CFD trading means buying or selling contracts for difference: derivatives that track price movements without giving you ownership of the underlying asset. You agree with a provider to settle the difference between the opening and closing prices, adjusted for position size and trading costs. As ASIC’s MoneySmart explanation of CFDs makes clear, this is speculation on prices, not direct ownership of shares, currencies or commodities.
The ability to trade rising and falling markets comes with substantial risk. In its January 2026 sector review, ASIC reported that 68% of retail CFD investors lost money during the 2024 financial year. Those Australian results are not a universal loss rate, but they are a useful counterweight to advertisements showing only profitable trades.
For U.S. readers: conventional retail CFD accounts are not available through U.S. regulated brokers, as reflected in OANDA’s U.S. product restrictions. An offshore website accepting an application does not establish legality; the SEC has taken enforcement action over unregistered securities derivatives sold to U.S. investors.
How CFD Trading Works
A retail CFD is usually an over-the-counter contract between you and its provider, rather than a security you purchase on an exchange. You choose a market, trade size and direction. A long position benefits from a price increase; a short position benefits from a decrease. Closing the position settles the trading result. Singapore’s MoneySense guide explains these contractual mechanics, including the provider’s role and the charges that affect the final outcome.
For a simple share CFD representing one share per unit, gross profit on a long trade equals:
(Closing price − opening price) × number of units.
For a short trade, reverse the price subtraction. Other contracts can use different multipliers or monetary values per point, so never assume that “one contract” means the same exposure across markets. The walkthrough of how CFD trading works covers the order process in more detail.
A CFD Trading Example
Suppose you buy 100 hypothetical share CFDs at £50 each, with each unit representing one share. Your market exposure is £5,000. Assuming a 20% margin requirement, you need £1,000 to open the position.
| Closing price | Price movement | Gross trading result |
|---|---|---|
| £52.50 | 5% increase | £250 profit |
| £50.00 | No change | £0 before costs |
| £47.50 | 5% decrease | £250 loss |
The £250 gain or loss equals 25% of the £1,000 opening margin. These simplified figures exclude spreads, commissions, financing and other adjustments. Actual execution prices and charges determine the final result.
If you instead sold 100 units at £50 and bought them back at £47.50, the gross profit would be £250. A rise to £52.50 would produce a £250 loss. The separate guide to going long and short with CFDs examines both directions.
Which Markets Can You Trade?
Common CFD markets include individual shares, stock indices, currency pairs and commodities. A provider’s selection may also include ETFs, bonds or interest rate products; IG’s published market range illustrates this variety. Availability depends on the provider, account entity and local rules.
Choose the market before choosing the trade size. Check its contract multiplier, trading hours, minimum order size and settlement currency. Two instruments appearing side by side on a platform need not have comparable exposure or costs. A position labeled “gold” also deserves a closer look: establish whether its price references a cash market or a dated futures contract.
Margin, Exposure and Forced Closure
Margin is collateral for a position, not its purchase price and not a maximum loss. Opening a larger exposure with a smaller deposit is called leverage. As IG’s explanation of CFD margin describes, gains and losses follow the full position size. A smaller required deposit does not make an unchanged position safer.
Keep three figures separate: market exposure, margin committed and total account equity. Suppose the earlier £5,000 position sits in an account containing £4,000. A £250 loss is 25% of its opening margin but 6.25% of starting account equity. Both percentages are correct; they describe different things.
Falling account equity can trigger forced closure. Under UK retail CFD margin rules, providers must close positions as soon as market conditions allow when account equity falls below 50% of the required margin. This is an account-level threshold, not permission to lose exactly half of each trade’s deposit.
Do not build a plan around receiving a warning and having time to respond. Study CFD margin and exposure alongside the provider’s margin call and stop-out arrangements before opening positions.
What CFD Trading Costs
A correct price forecast can still produce a poor return after charges. The FCA’s review of CFD pricing and value found wide differences in fees, particularly overnight funding. Comparing only the advertised spread misses part of the bill.
The main charges to examine are:
- Spread: the difference between buying and selling prices.
- Commission: a transaction charge, commonly applied to share CFDs.
- Overnight financing: a charge or adjustment for keeping certain positions open beyond the provider’s daily cutoff.
- Other charges: currency conversion, guaranteed stop premiums and any applicable account or data fees.
IG’s published charges show how these categories can appear in practice, although another provider’s pricing may differ. Read the complete CFD trading cost breakdown, including both entry and exit charges.
Financing can be calculated on the full exposure rather than only the margin deposit. For illustration, £5,000 charged at an assumed annual rate of 8% over 30 days, using a 365-day convention, costs about £32.88. That is not a live quotation; actual formulas and rates vary. Review overnight financing before deciding how long to hold.
Product structure matters too. Some futures-based CFDs have no separate daily funding charge, with carrying costs reflected in pricing instead. IG’s comparison of cash and futures-based CFDs explains its approach. “No overnight fee” does not mean “free to hold.” Check expiry and rollover terms.
Managing CFD Risk
Size the Trade Around a Planned Loss
Start with the amount you are prepared to lose, then work backward to position size. Do not begin with the largest order the platform permits.
For example, a £50 planned price loss and a stop £1 away from entry imply 50 share CFD units, assuming each unit represents one share. That calculation excludes fees and assumes execution at the stop price. Allowing for costs would require a smaller position if £50 were the total intended risk budget.
This is a sizing illustration, not a recommended risk allowance. Use CFD position sizing to connect the exit level, contract value and account balance rather than treating margin availability as spending money.
Know What a Stop Can and Cannot Do
A normal stop-loss order does not guarantee its execution price. A fast move or price gap can produce a worse exit, as MoneySense warns in its discussion of CFD market risk. The planned loss and the realized loss can therefore differ.
A guaranteed stop protects the chosen exit price under the provider’s terms. Availability and premiums need checking; IG’s guaranteed stop documentation, for example, specifies a premium when the stop triggers. Compare ordinary and guaranteed CFD stops before relying on either.
There is also provider risk. You depend on the issuer to meet its obligations, and regulation does not eliminate the possibility of failure. MoneySmart identifies counterparty and pricing risks alongside trading losses. A profitable position is not much comfort if the counterparty cannot pay.
Your broader CFD risk management plan should set a total exposure ceiling, a response to platform outages and a point at which trading stops for review. Write these decisions before a losing session, not during it.
CFDs Versus Investing and Hedging
A share CFD provides price exposure without shareholder ownership. Dividend-related amounts may be credited or debited under the contract, but they are contractual adjustments rather than dividends received as a shareholder. HMRC’s description of retail CFDs explains this distinction.
CFDs can also be used to offset an existing investment exposure. IG describes portfolio hedging with CFDs, including short positions against share holdings. In a simplified example, a short CFD matching a shareholding could gain as that holding falls, before costs. It would also lose as the shares rise.
That is not a free insurance policy. Ask whether selling part of the original holding would achieve the intended risk reduction more simply. Consider financing, taxes and whether the hedge actually matches the investment. The distinction between trading and investing helps frame that decision: a temporary price trade and an ownership plan serve different purposes.
Regulation and Retail Protections
Protections depend on jurisdiction and client classification. In the UK, retail rules include exposure limits, mandatory loss warnings and negative balance protection. The FCA’s CFD guidance also warns that moving to professional status or an overseas entity can remove protections. Negative balance protection restricts trading-related liability at account level; it does not prevent losing the account’s funds.
Australia has comparable restrictions, including margin close-out requirements and negative balance protection. ASIC extended its CFD intervention order through May 23, 2027. Do not assume the same terms apply to an account opened elsewhere.
Market permissions can differ too. The FCA prohibits firms from marketing, distributing or selling covered cryptoasset derivatives to retail clients. A product appearing on an international website does not establish that it is available to you.
Before Opening a CFD Account
Check the exact company that would hold your account, not just the brand name. Verify its authorization, permitted services and contact details against the regulator’s records. The FCA’s guidance on clone firms explains why a genuine registration number alone is insufficient. The process for checking a broker’s licence is useful when a provider offers both forex and CFDs.
Then request the contract specifications, execution policy, complete fee schedule and withdrawal terms. Use a demonstration account to rehearse order entry and closing positions, but do not treat simulated profits as evidence that a live strategy will succeed.
Keep trade confirmations and records of every adjustment. Tax treatment needs a jurisdiction-specific check: in the UK, HMRC generally treats retail CFD outcomes under capital gains rules unless trading-income treatment applies. Obtain qualified advice where your circumstances require it.
Before any live order, be able to state its full exposure, planned exit, expected holding cost and what could make the loss larger than planned. If any answer is missing, postpone the trade. The market does not charge a fee for staying out.
