What Is CFD Trading? How Contracts for Difference Work, with Examples
How contracts for difference work: profiting from rising and falling prices without owning the asset, leverage and margin, every cost, and the risks.

Quick answer: a CFD (contract for difference) is a contract with a broker to exchange the change in an asset's price between when you open and when you close a trade. If you buy and the price rises, you gain the difference; if you sell and it falls, you gain the difference. You never own the asset, you can trade rising and falling markets, and you trade on margin, which magnifies both gains and losses.
How a CFD trade works
Every CFD trade has the same four parts: the instrument, the direction, the size and the two prices.
Suppose EUR/USD is quoted at 1.1250 and you expect the euro to rise. You buy 1 lot (100,000 euros). Later the price is 1.1300 and you close.
Price change: 1.1300 - 1.1250 = 0.0050 Profit: 0.0050 × 100,000 = $500
Had the price fallen to 1.1200, the same trade would have lost $500. If you had expected the fall and sold instead, the numbers reverse: you make $500 on a fall to 1.1200 and lose $500 on a rise to 1.1300.
Nothing was delivered. No euros changed hands. The broker settled the difference in your account currency, which is the whole idea of a contract for difference.
Leverage and margin, without the jargon
To open that 1-lot EUR/USD position you do not need $112,500. You put up margin, a deposit that is a fraction of the position's value. At 1:100 leverage the margin is 1/100 of the value: about $1,125.
That is what makes CFDs efficient and what makes them dangerous. The $500 profit above is 44% of the margin, from a price move of less than half a percent. The same move the other way costs the same $500. The margin is not your maximum loss: losses come out of your whole balance, and if your margin level falls to the stop-out level, the platform closes positions automatically.
A useful rule: decide the dollar amount you are prepared to lose on a trade first, then choose a position size that loses exactly that if your stop-loss is hit. The position size calculator does the arithmetic, and the margin calculator shows the margin for any instrument and leverage.
What it costs to trade a CFD
Spread. You buy at the higher (ask) price and sell at the lower (bid) price. The gap is a cost you pay when you open. It varies with the instrument, the time of day and the account type.
Commission. Some accounts charge a commission per lot in exchange for tighter, raw spreads. At GCC Brokers the Standard and Pro accounts have no commission; the Zero account has raw spreads from 0.2 pips plus a commission. See account types.
Swap (overnight financing). A position still open at the daily rollover is charged or credited a swap, reflecting the interest cost of the leveraged position. It can be positive or negative, depends on the direction, and is tripled on one night of the week to cover the weekend. Our explainer on swap fees covers it in detail, and the swap calculator uses the live rates.
CFDs compared with owning the asset
| Buying the asset | Trading a CFD | |
|---|---|---|
| Ownership | You own it | Price exposure only |
| Profit from falling prices | No | Yes, by selling |
| Money needed | Full value | Margin, a fraction of the value |
| Holding cost | Custody, storage | Overnight swap |
| Dividends, delivery | Yes | No |
| Can lose more than you put in | No | Yes, with leverage |
CFDs suit traders who want short-term exposure to price moves in either direction across many markets from one account. Investors who want to own an asset for years are usually better served by buying it.

The risks, stated plainly
- Leverage magnifies losses as much as gains, and losses can exceed your deposit in fast markets.
- Prices can gap over weekends and around major news, past a stop-loss.
- Overnight costs accumulate on positions held for weeks.
- CFDs are traded with a broker, not on an exchange, so you depend on the broker's regulation and financial standing. GCC Brokers Limited is regulated by the Financial Services Commission of Mauritius (licence GB22200739), which you can verify on the regulation page.
GCC Brokers executes CFD orders through fully automated STP execution, with no requotes and no filtering by profitability.
Trading FX and CFDs on leverage carries significant risk and may not be suitable for all investors. You may lose more than your initial deposit.
