What is CFD trading and how does it work?

Trading contracts for difference (CFDs) is a way of speculating on financial markets that doesn’t require the buying and selling of any underlying assets. Find out everything you need to know to understand CFD trading, from what it is and how it works to short trades, leverage and hedging.

What is CFD trading?

CFD trading is defined as ‘the buying and selling of CFDs’, with ‘CFD’ meaning ‘contract for difference’. CFDs are a derivative product because they enable you to speculate on financial markets such as shares, forex, indices and commodities without having to take ownership of the underlying assets.

Instead, when you trade a CFD, you are agreeing to exchange the difference in the price of an asset from the point at which the contract is opened to when it is closed. One of the main benefits of CFD trading is that you can speculate on price movements in either direction, with the profit or loss you make dependent on the extent to which your forecast is correct.

The sections that follow explain some of the main features and uses of contracts for difference:

  • Short and long trading
  • Leverage
  • Margin
  • Hedging

Short and long CFD trading explained

CFD trading enables you to speculate on price movements in either direction. So while you can mimic a traditional trade that profits as a market rises in price, you can also open a CFD position that will profit as the underlying market decreases in price. This is referred to as selling or ‘going short’, as opposed to buying or ‘going long’.

If you think Apple shares are going to fall in price, for example, you could sell a share CFD on the company. You’ll still exchange the difference in price between when your position is opened and when it is closed, but will earn a profit if the shares drop in price and a loss if they increase in price.

With both long and short trades, profits and losses will be realised once the position is closed.

Leverage in CFD trading explained

CFD trading is leveraged, which means you can gain exposure to a large position without having to commit the full cost at the outset. Say you wanted to open a position equivalent to 500 Apple shares. With a standard trade, that would mean paying the full cost of the shares upfront. With a contract for difference, on the other hand, you might only have to put up 20% of the cost.

While leverage enables you to spread your capital further, it is important to keep in mind that your profit or loss will still be calculated on the full size of your position. In our example, that would be the difference in the price of 500 Apple shares from the point you opened the trade to the point you closed it. That means both profits and losses can be hugely magnified compared to your outlay, and that losses can exceed deposits. For this reason, it is important to pay attention to the leverage ratio and make sure that you are trading within your means.

Margin explained

Leveraged trading is sometimes referred to as ‘trading on margin’ because the funds required to open and maintain a position – the ‘margin’ – represent only a fraction of its total size.

When trading CFDs, there are two types of margin. A deposit margin is required to open a position, while a maintenance margin may be required if your trade gets close to incurring losses that the deposit margin – and any additional funds in your account – will not cover. If this happens, you may get a margin call from your provider asking you to top up the funds in your account. If you don’t add sufficient funds, the position may be closed and any losses incurred will be realised.

Hedging with CFDs explained

CFDs can also be used to hedge against losses in an existing portfolio.

For example, if you believed that some ABC Limited shares in your portfolio could suffer a short-term dip in value as a result of a disappointing earnings report, you could offset some of the potential loss by going short on the market through a CFD trade. If you did decide to hedge your risk in this way, any drop in the value of the ABC Limited shares in your portfolio would be offset by a gain in your short CFD trade.

How do CFDs work?

Now you understand what contracts for difference are, it’s time to take a look at how they work. Here we explain four of the key concepts behind CFD trading: spreads, deal sizes, durations and profit/loss.

1. Spread and commission

CFD prices are quoted in two prices: the buy price and the sell price.

  • The sell price (or bid price) is the price at which you can open a short CFD
  • The buy price (or offer price) is the price at which you can open a long CFD

Sell prices will always be slightly lower than the current market price, and buy prices will be slightly higher. The difference between the two prices is referred to as the spread.

Most of the time, the cost to open a CFD position is covered in the spread: meaning that buy and sell prices will be adjusted to reflect the cost of making the trade.

The exception to this is share CFDs, which are not charged via the spread. Instead, the buy and sell prices match the price of the underlying market and the charge for opening a share CFD position is commission-based. By using commission, the act of speculating on share prices with a contract for difference is closer to buying and selling shares in the market.

2. Deal size

CFDs are traded in standardised contracts (lots). The size of an individual contract varies depending on the underlying asset being traded, often mimicking how that asset is traded on the market.

Silver, for example, is traded on commodity exchanges in lots of 5000 troy ounces, and its equivalent contract for difference also has a value of 5000 troy ounces. For share CFDs, the contract size is usually representative of one share in the company you are trading. To open a position that mimics buying 500 shares of HSBC, you’d buy 500 HSBC CFD contracts.

This is another way in which CFD trading is more similar to traditional trading than other derivatives, such as spread bets or options.

3. Duration

Most CFD trades have no fixed expiry – unlike spread bets and options. Instead, a position is closed by placing a trade in the opposite direction to the one that opened it. A buy position of 500 gold contracts, for instance, would be closed by selling 500 gold contracts.

If you keep a daily CFD position open past the daily cut-off time (typically 10pm UK time, although this may vary for international markets), you’ll be charged an overnight funding charge. The cost reflects the cost of the capital your provider has in effect lent you in order to open a leveraged trade.

This isn’t always the case though, with the main exception being a forward contract. A forward contract has an expiry date at some point in the future, and has all overnight funding charges already included in the spread.

4. Profit and loss

To calculate the profit or loss earned from a CFD trade, you multiply the deal size of the position (total number of contracts) by the value of each contract (expressed per point of movement). You then multiply that figure by the difference in points between the price when you opened the contract and when you closed it.

Profit or loss = (no. of contracts x value of each contract) x (closing price - opening price)

For a full calculation of the profit or loss from a trade, you’d also subtract any charges or fees you paid. These could be overnight funding charges, commission or guaranteed stop fees.

Say, for instance, that you buy 50 FTSE 100 contracts when the buy price is 7500.0. A single FTSE 100 contract is equal to a £10 per point, so for each point of upward movement you would make £500 and for each point of downward movement you would lose £500 (50 contracts multiplied by £10).

If you sell when the FTSE 100 is trading at 7505.0, your profit would be £2500.

2500 = (50 x 10) x (7505.0 - 7500.0)

If you sell when the FTSE 100 is trading at 7497.0, your loss would be £1500.

-1500 = (50 x 10) x (7497.0 - 7500.0)

FAQs

Can I trade CFDs without leverage?

Some providers allow you to trade CFDs without leverage. With IG, however, all CFD trades are leveraged. The amount of leverage offered depends on various factors including the volatility and liquidity of the underlying market, as well as the law in the country in which you are trading.

How do I use CFDs for hedging?

The way to use CFDs for hedging is by opening a position that will become profitable if one of your other positions begins to incur a loss. An example of this would be taking out a short position on a market that tracks the price of an asset you own. Any drop in the value of your asset would then be offset by the profit from your CFD trade.

Say, for example, you hold a number of shares in Apple but believe these shares may fall in value in the future. You could go short on Apple via a share CFD. If you are correct and your Apple shares fall in value, then the profit from your short CFD trade will offset this loss.

What is the difference between CFDs and futures?

When you trade CFDs (contracts for difference), you buy a certain number of contracts on a market if you expect it to rise, and sell them if you expect it to fall. The change in the value of your position reflects movements in the underlying market. With CFDs, you can close your position any time when the market is open.

Futures, on the other hand, are contracts that require you to trade a financial instrument in the future. Unlike CFDs, they specify a fixed date and price for this transaction – which can involve taking physical ownership of the underlying asset on this date – and must be purchased via an exchange. The value of a futures contract depends as much on market sentiment about the future price of the asset as current movements in the underlying market.

It is worth keeping in mind that with an IG spread betting or CFD trading account, you can speculate on the price of futures contracts without having to buy the contracts themselves
