Why trade CFDs?
1) Make your capital go further with leverage
CFDs enable you to stretch your investment capital further, as you only have to deposit a fraction of your trade’s full value to open a position. The deposit you’ll have to put down is called a margin. While this lowers the cost of opening a trade, it can also amplify your losses. This is because CFD profits and losses are calculated on the full size of your trade.
How much you’ll need to deposit depends on the size of your position and the margin factor for your chosen market. For example, many of our share CFDs have a margin of 20%, most major indices have a margin of 5% and most major forex pairs have a margin of 3.33%. Learn more about our CFD margin requirements.
For an easy way to find out the margin requirement for your trade – as well as the potential profit or loss – try out our CFD calculator. An example would be if you decided to trade CFD shares on BT, which has a margin factor of 20%. In this case, a position worth £1000 would only require a deposit of £200.

However, it’s important to remember that your total profit or loss is based on the full size of your position, not your margin. So, in our previous example of BT share CFDs, your potential for loss or profit would be based on the full £1000, even though you only paid £200 to open the position.
The benefits of CFDs vs share dealing: a comparison
Let’s continue with the example of you wanting to open a CFD shares position worth £1000. The below table illustrates the benefits and risks of CFDs, compared to investing in shares.
CFD trade
Your deposit is a margin of £200
If your BT position rises to £1025, you’ll make £25, excluding any fees and charges
If your BT position falls to £975, you’ll lose £25, excluding any fees and charges
Investment
Your deposit is the full £1000
If your BT position rises to £1025, you’ll make £25, excluding any fees and charges
If your BT position falls to £975, you’ll lose £25, excluding any fees and charges
Differences between CFDs and share dealing
2) Go short or long
When you trade CFDs on our platform, you’ll see two prices listed: the ‘buy’ price and the ‘sell’ price. You’ll trade at the buy price if you think that the market is going to go up in price (known as going long), and the sell price if you think it is going to go down in price (known as going short).
If your prediction is correct, you will make a profit based on your overall position (not the initial margin amount you paid to open the trade), which can exceed the initial cost of your margin. However, if your prediction is incorrect and you make a loss, that loss is also calculated based on your total position size. This means that your losses can far outweigh the margin cost, so always ensure you are trading within your means.
3) Trade a huge range of markets
With us, you can trade CFDs on more than 15,000+ markets. This includes over 11,000+ shares and ETFs, 80 of the world’s top indices, 30 commodities, all major, minor and exotic forex pairs and more.

We have some of the best pre-market and after-hours offerings available, so you can trade long before and after the main market session on our All Session stocks and indices.
Just keep in mind that the market’s opening price may differ from its out-of-hours price and that trades opened and not closed by 10pm (UK time) will incur overnight funding charges

4) Mirror trading the underlying market
CFDs are designed to mimic trading their underlying market fairly closely. This means you simply buy and sell CFDs as you would the underlying asset. For example, buying an Apple share CFD is the equivalent of buying a single share in Apple – if you want to buy the equivalent of 2000 Apple shares, you’d buy 2000 Apple CFDs.
Buying or selling a forex CFD, meanwhile, is equivalent to buying a certain amount of base currency by selling the equivalent amount of quote currency. These are called lots and there are different sizes of lots for forex: standard, mini, micro and nano. The greater the lot size, the more money you’ll need to put down to open a position. So, buying a single CFD on the GBP/USD exchange would give you the same exposure as buying £100,000 in US dollars for a standard lot, but £1000 with a mini lot. Find out more about lot sizes for forex.
With commodities and indices, the points a market moves are directly correlated to the real-time price of that index or commodity.
5) Pay no stamp duty on your profits
Your profits from CFD trades are generally exempt from stamp duty in the UK.* However, it’s important to remember that tax law may differ in a jurisdiction other than the UK. These laws are subject to change and depend on individual circumstances.
Most traders will pay capital gains tax on their CFD trade profits, but this can be offset any losses against profits for your capital gains tax (CGT) liabilities.* This means trading CFDs can be a great way of hedging – which we explain below.
5) Hedging your share portfolio
If you have other active trades or investments, you can use CFDs to hedge risk in both your leveraged and non-leveraged portfolios. Hedging means you strategically open new positions (such as CFD trades) to protect existing positions from unpredictable market movements or offset potential losses.
For example, let’s say that you owned HSBC shares outright but the price was starting to fall. You don’t want to sell your share investment, but you also don’t want to run the risk of the share price falling to a level that you’re uncomfortable with – which might represent a loss.
So, you open a short share CFD position on HSBC (‘sell’ rather than ‘buy’) with the same size as your share investment. If the HSBC share price falls, the gains on your short share CFD trade will help to offset a proportion of the losses on your share investment – without requiring you to sell your shares.
If you’re correct and your HSBC shares drop in value, then your HSBC CFD trade position would earn you a profit, offsetting your loss. If your HSBC shares increase in value, you could close your CFD position – and offset the loss you incurred against future profits for capital gains tax purposes.*

7) Benefit from DMA
If you’re an advanced trader, you can get direct market access (DMA). Our DMA offering enables you to see and interact with the order books of stock exchanges. Instead of trading at the buy and sell prices offered by us, you can see all the available bid and offer prices at any time and trade at market prices you choose.
Using DMA means there’s no spread to pay because these trades are charged on commission. But, while DMA can be a powerful tool, there’s no guarantee that you’ll find prices that are better than the prices we offer.
DMA is only recommended if you’re an advanced trader with plenty of experience, due to the risks and complexities involved.
