What is indices trading and how does it work?

Learn all about indices CFD (contracts for difference) trading, with information on the types of indices, how they work, market trading hours, and how to trade indices CFDs.
What is indices trading?
Indices trading lets you speculate on stock-market benchmarks – including the US 500, UK 100 or Germany 40 – without owning the underlying shares. This is done using derivatives such as CFDs. Each index represents the performance of a selected group of publicly listed companies, typically from a specific country, region or sector, and is often weighted by market capitalisation.
Rather than trading individual stocks, traders use indices to gain broader market exposure. Index prices rise or fall based on the weighted average performance of their constituent stocks, as well as broader market trends.
When you trade indices CFDs with us, you can speculate on the overall direction of an economy or sector, hedge existing positions, or take advantage of market volatility – all without needing to analyse or manage multiple single-stock positions.
CFDs are traded on margin, and carry a high risk of loss.
What are the types of indices CFDs in trading?
Indices are broadly grouped into categories based on how they are constructed and what they represent, which includes: national indices, sector indices, volatility indices, and currency indices.
National indices
When you trade national indices CFDs, you’re speculating on the performance of a selection of companies listed in a specific country.
These include major benchmarks like the US 500 (S&P 500), UK 100 (FTSE 100), Germany 40 (DAX 40), and Japan 225 (Nikkei 225). Most national indices are weighted by market capitalisation, meaning larger companies have a greater impact on index price movements. Others, such as the US Wall Street 30 (Dow Jones), are price-weighted, where higher-priced stocks carry more influence.
Sector indices
Sector indices CFDs focus on particular segments of the economy, such as technology, energy, or healthcare. These indices reflect the performance of companies within a specific industry. For example, our Hong Kong Tech Index CFD tracks major technology firms listed in Hong Kong, while other indices CFDs may focus on financials, industrials, or consumer goods.
Volatility indices
Volatility indices CFDs, such as our Volatility Index CFD (VIX), measure implied market volatility. These are based on the pricing of options and do not track company shares directly. They can help gauge market sentiment or hedge against risk.
Currency indices
Currency indices CFDs track the performance of a single currency against a weighted basket of others. For instance, our US Dollar Index CFD (DXY) measures the value of the US dollar relative to six major currencies, including the euro, Japanese yen and British pound, with the euro carrying the heaviest weighting. Forex CFD traders might use currency indices CFDs to assess currency strength or to hedge exposure.
CFDs are complex instruments and come with a high risk of losing money rapidly due to margin. Ensure that you understand how CFDs work, and determine whether you can afford to take the high risk of losing your money.
How does indices CFD trading work?
Indices CFDs let you speculate on whether an index will rise or fall without buying any of the underlying shares or futures contracts. Indices CFDs can be traded on margin, which means profits and losses are magnified relative to your deposit. Here’s how indices CFD trading works.
‘Buy’ and ‘sell’ positions
When trading indices CFDs, you can take a long position if you believe the index will rise, or go short if you expect it to fall. For example, a trader expecting the US 500 to increase might go long using our US 500 CFD, aiming to profit from upward price movement. If the market moves the other way, losses can mount just as quickly.
Spreads and trading costs
The primary cost of trading indices CFDs is the spread – the difference between the buy and sell price. You pay the spread when opening a position. There may also be overnight fees if you hold positions beyond the trading day, or additional charges for using risk management tools such as guaranteed stop-losses. See our charges and fees page to understand the total cost of trading.
Weighting and price movement
Each index has its own weighting method. Capitalisation-weighted indices – like the Germany 40 – give more influence to larger companies. Price-weighted indices, such as the US Wall Street 30, are influenced more by stocks with higher share prices, regardless of company size. Indices CFDs mirror these weightings, so the price of our CFDs tracks the same calculations.
Leverage and margin
Indices CFDs are traded on margin. This means you only need to deposit a fraction of the trade’s full value to open a position. While this can increase potential returns, it also magnifies potential losses, which can exceed your deposit. Use margin carefully and monitor margin requirements at all times.
Liquidity and execution
Major indices CFDs can experience high liquidity, especially during their core trading hours. High liquidity can result in tighter spreads and faster execution, making it easier to enter or exit trades at intended prices. However, periods of high volatility can still lead to slippage due to rapid price movements, even in otherwise liquid markets.
Market access
Indices CFDs can be traded on our regulated, easy-to-use web platform and mobile apps. While trading may be available outside standard exchange hours, indices are typically most active during local market hours – for example, the US 500 is most active when US markets are open.
What is an example of indices CFD trading?
Germany 40 CFD – short position
Let’s say you want to trade a CFD on the Germany 40 (DAX 40) index at a price of 16,000.
After conducting some fundamental analysis on the market, this time you think it will fall.
You open a short Germany 40 CFD at £10 per point. This gives you a notional exposure of £160,000 (16,000 × £10). With a 5% margin requirement, you only have to put down £8,000.
Over a few hours, the price rises by 40 points to 16,040 and you close the position.
You’ve made a loss of £400 (40 × £10), minus the spread and any overnight funding charges if held overnight.Germany 40 CFD – long position
Now suppose you believe the Germany 40 (DAX 40) will rise and the quoted CFD price is 16,000. You open a long Germany 40 CFD at £10 per point, giving you a notional exposure of £160,000 (16,000 × £10). With a 5 % margin requirement, you deposit £8,000.
A few hours later the index rises 40 points to 16,040 and you close the position.
You make a gross profit of £400 (40 × £10), minus the spread and any overnight funding charges if applicable. Losses would have occurred had the market moved lower.
Where can you trade indices CFDs?

Indices CFD trading: What are the risks and benefits?
Trading indices via CFDs brings potential opportunities and risks, influenced by factors such as leverage, volatility and market composition. CFDs are derivatives, which means you speculate on price movements in the underlying index and do not own any constituent shares.
Diversification
CFDs on indices can give you price exposure to a basket of shares, potentially reducing company-specific risk. However, you still do not own any of the underlying stocks, and many popular indices are heavily weighted towards a handful of large firms or sectors, so the diversification benefit may be limited.
Market access
Indices CFDs let you speculate on global benchmark performance without buying the underlying shares. This flexibility can also encourage over-trading or exposure to unfamiliar time zones, and your net return will differ from the cash index after spreads, overnight funding and any other applicable costs.
Volatility
Indices CFDs can react sharply to economic data, interest rate decisions, and geopolitical events. Sudden price movements may create short-term opportunities, but also increase the risk of slippage and unexpected losses.
Leverage and margin
Leverage allows traders to open larger positions with a smaller deposit, magnifying both gains and losses. Ensure you understand the risks involved when trading indices CFDs, use risk management tools, and never trade more than you can afford to lose.
Systemic risk
Unlike individual shares CFDs, an index CFD represents a broad slice of the market. As a result, indices CFDs may be exposed to wider economic shocks. During market-wide sell-offs, correlations between assets often rise, reducing diversification benefits and amplifying downside risk.
CFDs are complex instruments and come with a high risk of losing money rapidly due to margin.
What are some indices CFD trading strategies?
Indices CFD traders can combine technical and fundamental analysis with disciplined risk management. While they do provide guidance and structure, trading strategies don’t completely eliminate risks and past performance is not a reliable indicator of future results.
Scalp trading strategy
Scalping is a short-term strategy where traders aim to profit from small price movements by opening multiple CFD positions throughout the day. Positions are held for seconds or minutes, often using indicators such as moving averages, RSI or chart patterns on high-liquidity indices CFDs like the US 500 or Germany 40.
Trend trading strategy
Trend trading involves identifying and trading in the direction of a broader market move. Traders typically use tools such as MACD or moving averages to confirm trend strength before entering long or short CFD positions on indices such as the UK 100 or US Tech 100.
Swing trading strategy
Swing traders hold indices CFD positions for several days to weeks, aiming to capture medium-term price moves. Both fundamental and technical analysis are used to guide the timing of potential entry and exit points, often around key levels or major economic releases that influence index sentiment.
Range trading strategy
Range trading focuses on indices CFDs that oscillate within a defined price band. Traders might go long near support and short near resistance, using tools like Bollinger Bands or stochastic oscillators to spot potential reversals. Breakouts can invalidate range setups, so risk parameters should be clearly defined in advance.
