Key takeaways
- A CFD is a contract to exchange the difference in an asset's price between opening and closing a position.
- You never own the underlying asset, and you can open a position on a rising or a falling price.
- CFDs are traded with leverage, so a small margin controls a large position and losses grow as fast as gains.
- Costs include the spread, a commission on some accounts, and swap for positions held overnight.

A CFD in plain words
A contract for difference (CFD) is a contract between you and a broker to exchange the difference in an asset's price between the moment a position is opened and the moment it is closed. If the difference is in your favour, the broker pays it to you; if it is against you, you pay it.
You never buy or hold the asset itself: no gold bars, no shares of an index, no coins in a crypto wallet. The CFD simply tracks the asset's price. That is what lets you open a position on a falling price as easily as on a rising one.
At NextTrade, forex, metals, energies and indices are all traded as CFDs. The price you see in the platform follows the price of the underlying market, plus the broker's spread.
How a CFD trade works
- You choose an instrument, for example gold (XAU/USD) or a stock index.
- You decide the direction: buy (go long) or sell (go short).
- You set the size, in lots or contracts, and the platform reserves the margin.
- While the position is open, its profit or loss changes with every price move.
- When you close it, the difference between the opening and closing prices, multiplied by the size, is added to or taken from your balance.
The calculation is the same for every CFD: (closing price − opening price) × size for a buy, and the reverse for a sell. Costs are then taken off the result, as described below.
What you can trade with CFDs
CFDs exist on many kinds of asset. At NextTrade they cover forex pairs, metals, energies, indices and crypto. Each asset class has its own maximum leverage, because some markets usually move more than others.
| Asset class | Examples | Max leverage |
|---|---|---|
| Forex majors | EUR/USD, GBP/USD, USD/JPY | Up to 1:1000 |
| Forex minors | EUR/GBP, AUD/CAD, NZD/JPY | Up to 1:1000 |
| Forex exotics | USD/TRY, EUR/ZAR, USD/MXN | Up to 1:200 |
| Gold (XAU/USD) | Spot gold | Up to 1:200 |
| Oil (WTI/Brent) | Crude oil CFDs | Up to 1:100 |
| Indices | S&P 500, NASDAQ, DAX | Up to 1:200 |
| Crypto CFDs | BTC/USD, ETH/USD | Up to 1:10 |
Leverage and margin
CFDs are leveraged. To open a position you put up a margin, a fraction of the position's value, and gains and losses are calculated on the full position. NextTrade offers leverage of up to 1:1000; the leverage guide shows how the margin is calculated.
Leverage works both ways
A price move against your position is taken from your account in full, however small the margin. A move of a fraction of a percent can use up the whole margin.
Hypothetical example: a 1% move on a leveraged position
- Position
- 0.5 lots of EUR/USD ($50,000)
- Leverage (hypothetical setting)
- 1:200
- Margin: $50,000 ÷ 200 = $250
- Price moves 1% in your favour: gain of $500
- Price moves 1% against you: loss of $500
Result: a 1% move is a gain or a loss of $500, 2 times the $250 margin, before costs.
Read the risk warning before you use leverage.
At NextTrade, a margin call occurs when your equity drops to 100% of your used margin. It is an alert only: it does not close positions. If the margin level falls to 50%, the stop out closes positions automatically, starting with the one with the largest loss. In fast markets, a stop out may not prevent larger losses.
CFDs compared with owning the asset
| Question | CFD | Owning the asset |
|---|---|---|
| Do you own the asset? | No, you hold a contract on its price | Yes |
| Can you open a position on a falling price? | Yes, by selling | Not directly |
| Is leverage used? | Yes, you put up a margin | Usually not; you pay the full price |
| Are there overnight costs? | Swap on positions held overnight | Possibly storage or custody fees |
Because you do not own the asset, a CFD carries no ownership rights, such as shareholder votes. It is a way to gain or lose from price changes, not a way to hold the asset.
CFD costs and risks
Costs
- Spread: the difference between the buy and sell price, paid when you open a position.
- Commission: charged on some account types. At NextTrade, Raw accounts pay $7 per standard lot on forex, round trip (opening and closing).
- Swap: a charge or credit for each night a position stays open. Swap rates for each instrument are shown in the platform.
Risks
- Leverage: losses are calculated on the full position, so they can be large compared with the margin.
- Gaps and slippage: prices can jump past your order level, for example when the market reopens after the weekend.
- Costs add up: spreads and swap reduce every result, including losing trades.
NextTrade offers negative balance protection on all retail accounts, meaning clients cannot lose more than the funds available in their trading account. You can still lose all of those funds.
Hypothetical example: a gold CFD that gains or loses
- Position
- Buy a gold CFD on 10 ounces
- Opening price
- $2,000 an ounce
- Closed at $2,050: $50 × 10 ounces = +$500
- Closed at $1,950: −$50 × 10 ounces = −$500
Result: a gain of $500 or a loss of $500, before costs (spread, commission and swap).

Hypothetical example: a short index CFD that gains or loses
- Position
- Sell 1 index CFD worth $1 per point
- Opening price
- 20,000
- Index falls to 19,800: 200 points × $1 = +$200
- Index rises to 20,200: 200 points × $1 = −$200
Result: a gain of $200 or a loss of $200, before costs. A short position loses when the price rises.

Risk warning
Contracts for Differences (CFDs) are complex instruments and come with a high risk of losing money rapidly due to leverage. Visitors should carefully assess whether they understand how CFDs work and whether they can afford to take the high risk of losing their capital.
This guide is for education only. It is not investment advice or a recommendation to buy or sell any instrument. The examples use hypothetical figures, not past or expected results. Please review our Risk Disclosure Policy.
Frequently asked questions
Do you own the asset when you trade a CFD?
No. A CFD is a contract on the price of an asset, not the asset itself. When you open a gold CFD, you hold no gold: you and the broker exchange the difference between the opening and closing prices. That is why you can open a position on a falling price, and why a CFD carries no ownership rights.
Can you lose more than you deposit with CFDs?
With leverage, losses can be larger than the margin you put up for a trade. At account level, NextTrade offers negative balance protection on all retail accounts, meaning clients cannot lose more than the funds available in their trading account. You can still lose all of the money in your account.
What is the difference between forex and CFDs?
Forex is a market: the exchange of one currency for another. A CFD is a type of contract that can track many markets, including forex, metals, energies, indices and crypto. At NextTrade, forex is traded as CFDs, so a forex position you open here is a CFD on a currency pair.
Why are CFDs considered high risk?
Mainly because of leverage. A small margin controls a large position, so a small price move against you can use up the margin quickly. Prices can also gap past your orders, and costs such as spreads and swap reduce every result. CFDs are complex instruments and come with a high risk of losing money.
