Our Take On Pepperstone
"Pepperstone is a premier trading platform, providing tight spreads, swift execution, and sophisticated charting tools for seasoned traders. Beginners benefit from no minimum deposit, comprehensive learning materials, and outstanding 24/7 support."
Tobias Robinson
Reviewer
Pros
- Pepperstone now offers spread betting via TradingView, delivering a streamlined and tax-efficient trading experience with sophisticated analytical tools.
- In recent years, Pepperstone has significantly enhanced the deposit and withdrawal process. By 2025, clients can use Apple Pay and Google Pay, while 2024 saw the introduction of PIX and SPEI for customers in Brazil and Mexico.
- Pepperstone presents itself as an economical choice for traders, offering spreads as low as 0.0 in its Razor account. The Active Trader programme provides rebates up to 30% on indices and commodities, plus $3 per lot on forex.
Cons
- Pepperstone's demo accounts expire after 30 days, which may not provide sufficient time to explore various platforms and evaluate trading strategies.
- Pepperstone doesn't offer cTrader Copy, a favoured feature for copying trades found in the cTrader platform, which is available on other platforms such as IC Markets. However, Pepperstone has launched its own user-friendly copy trading app.
- Although its market range has improved, its crypto offerings remain limited compared to brokers specialising in this sector, lacking real coin investment options.
Our Take On CMC Markets
"Equipped with advanced charts and a broad array of tradable CFDs, including an unmatched selection of currencies and bespoke indices, CMC Markets offers an excellent online platform for traders at any level."
Pros
- CMC provides competitive pricing with narrow spreads and low trading fees, except for stock CFDs. The Alpha and Price+ programmes offer additional benefits for active traders, including discounts on spreads of up to 40%.
- The CMC web platform offers an exceptional user experience with sophisticated charting tools for trading and customisable options, suitable for both novice and seasoned traders. It supports MT4 but not MT5, and TradingView will be available from 2025.
- CMC Markets is well-regulated by respected financial authorities, ensuring a secure and reliable trading environment. It upholds a strong reputation, providing traders with confidence.
Cons
- Trading stock CFDs comes with a relatively high commission, particularly when compared to low-cost brokers such as IC Markets.
- A monthly inactivity charge of $10 is imposed after a year's inactivity, potentially discouraging occasional traders.
- CMC provides a robust range of assets; however, it does not support trading actual stocks, and UK clients are unable to trade cryptocurrencies.
Our Take On FXPro
"FxPro is an excellent choice for traders, offering swift execution speeds under 12ms, reduced fees since 2022, and outstanding charting platforms like MT4, MT5, cTrader, and FxPro Edge."
Pros
- FxPro's Wallet is a notable feature enabling traders to securely manage their funds. It ensures additional protection and ease by separating unused funds from active trading accounts.
- FxPro uses a 'No Dealing Desk' (NDD) model for swift and transparent order execution, usually within 12 milliseconds, making it well-suited for short-term trading strategies.
- FxPro provides four dependable charting platforms, including the user-friendly FxPro Edge. It features more than 50 indicators, 7 types of charts, and 15 different timeframes.
Cons
- FxPro offers customer support five days a week around the clock, accessible via various platforms, and the service quality is reliable based on tests. However, the absence of weekend support can be a drawback for traders requiring help beyond standard market times.
- There are no passive investment options such as copy trading or interest on cash. While traders might not find these essential, competitors like eToro, which accommodate both active and passive investors, offer more extensive services.
- FxPro, with its $10M funded demo account and expanding Knowledge Hub, mainly caters to experienced traders. Beginners might find its account and fee structure challenging to understand.
Our Take On IG Index
"IG offers a complete package with an intuitive online platform, top-tier beginner education, advanced charting tools through its TradingView integration, real-time data, and swift execution for seasoned traders."
Pros
- IG stands out with its extensive range of instruments, offering stocks, forex, indices, commodities, and cryptocurrencies. Additionally, it has recently introduced US-listed futures and options, along with an AI Index. These options enhance opportunities for diversification in trading.
- As a seasoned broker, IG adheres to stringent regulatory standards across various regions, ensuring significant trust.
- The IG app provides an excellent mobile trading experience with an intuitive design, earning it the Runner Up position in our 'Best Trading App' award.
Cons
- Based on tests, stock and CFD spreads remain less competitive than the lowest-cost brokers, such as CMC Markets.
- Beginners may find IG's fees complicated, as they vary depending on the trades or services. This could cause confusion and unexpected costs.
- IG has ended its swap-free account, diminishing its attractiveness to Islamic traders.
Our Take On eToro
"eToro's social trading platform excels with its outstanding user experience and lively community chat, aiding beginners in spotting opportunities. It offers competitive fees on numerous CFDs and real stocks, alongside exceptional rewards for seasoned strategists."
Pros
- eToro has enhanced its investment portfolio by frequently introducing new crypto assets. It currently offers a selection of over 100 digital currencies.
- eToro has launched automated crypto staking, offering a pathway to passive income. However, Ethereum requires users to opt in.
- Diverse investment portfolios are accessible, encompassing traditional markets, technology, cryptocurrency, and beyond for traders.
Cons
- The only significant contact option, besides the in-platform live chat, is limited.
- The minimum withdrawal is set at $30, accompanied by a $5 fee. This may impact traders with limited funds, particularly those just starting out.
- There are no assured stop-loss orders, which could be a valuable risk management tool for novice traders.
Our Take On Eightcap
"Eightcap excels for traders, offering diverse charting platforms, educational Labs, and AI tools. With over 120 crypto CFDs, it stands out in crypto trading and has won our 'Best Crypto Broker' award twice consecutively."
Pros
- In 2021, Eightcap enhanced its lineup, now providing an extensive range of cryptocurrency CFDs. It offers crypto/fiat and crypto/crypto pairs, along with crypto indices for comprehensive market exposure.
- With spreads starting at 0 pips, minimal commission charges, and leverage up to 1:500 for select clients, Eightcap delivers affordable and flexible trading opportunities. These conditions suit various strategies, such as trading and scalping.
- Eightcap has excelled in all essential trading areas, surpassing all rivals to clinch our 'Best Overall Broker' award for 2024. It also earned the titles of 'Best Crypto Broker' and 'Best TradingView Broker' for 2025.
Cons
- Eightcap must enhance its range of over 800 instruments to rival top competitors like Blackbull Markets, which offers 26,000+ assets, especially improving its limited commodities selection.
- Despite a helpful array of educational guides and e-books in Labs, Eightcap lags behind IG's extensive resources for aspiring traders. IG boasts a dedicated Academy app and features 18 diverse course categories.
- The demo account is available for 30 days, after which it requires a request for extension. This is less convenient than XM's offering, which provides an unlimited demo mode.
Our Take On Vantage FX
"Vantage is an ideal choice for CFD traders looking for a well-regulated broker with access to the dependable MetaTrader platforms. With a swift sign-up process and a minimum deposit of $50, starting trading is simple and fast."
Pros
- Opening a live account is both straightforward and swift, requiring under 5 minutes to complete.
- ECN accounts offer competitive terms, featuring spreads starting at 0.0 pips and a commission of $1.50 per trade side.
- With a minimal deposit requirement of just $50 and no funding fees, this broker stands out as an excellent option for novice traders.
Cons
- Regrettably, cryptocurrencies are accessible solely to clients in Australia.
- To access optimal trading conditions, a substantial deposit of $10,000 is required. This includes a commission of $1.50 per transaction per side.
- It's unfortunate that some clients must register with the offshore firm, which provides reduced regulatory safeguards.
What Does The US Dollar Index Represent?
The US dollar index is a live measure of the US dollar relative to a basket of other major currencies, including the British pound, euro, Japanese yen, Canadian dollar, Swedish krona, and Swiss franc.
The index is computed using a weighted average of exchange rates between the US dollar and these other currencies.
It was first introduced in 1973 by the New York Board of Trade and measures the strength or weakness of the US dollar in global currency markets.
The US dollar index is also sometimes referred to as USDX or DXY, which is its ticker symbol on trading platforms.
How Does The US Dollar Index Work?
The US dollar index is calculated using a weighted geometric mean of the exchange rates between the US dollar and six major currencies. The weightings are based on the relative importance of each currency in US trade.
The index measures the value of the US dollar against a basket of currencies, rather than against any single currency because it’s a more accurate and stable measure of the currency’s value. This means fluctuations in the value of one currency may be offset by movements in the other currencies in the basket. This helps to reduce the impact of volatility in any one currency on the overall value of the index.
To calculate the US dollar index, each currency’s exchange rate is first converted into an equivalent percentage value relative to the US dollar. For example, if the exchange rate for the euro is 1.2 dollars, the percentage value would be 83.33 (1 divided by 1.2, multiplied by 100). These percentage values are then multiplied by their respective weightings, and the resulting values are summed up to create the index value.
The US dollar index is calculated in real-time throughout the trading day and is widely used by traders, investors, and policymakers to monitor the strength of the US dollar. A higher index value indicates that the US dollar is stronger relative to the basket of currencies, while a lower one indicates it’s weaker.
Note, brokers may have their own components and respective weightings in the US dollar index, such as CMC Markets below. These will be detailed in the product specifications.
CMC Markets US Dollar Index Components
Background Explained
The US dollar index dates back to 1973 when the US government officially ended the gold standard and allowed the US dollar to float freely. Before this, there was a fixed relationship between the US dollar index and the price of gold.
The New York Board of Trade (now part of the Intercontinental Exchange) introduced the US dollar index in March 1973 and it was set at a base level of 100, calculated using the currencies of the US’s major trading partners at the time.
The composition of the spot index has changed to reflect shifts in global trade patterns. In 1999, the euro was added as a component currency, and in 2000, the Deutsche mark was replaced by the euro as Germany’s official currency. In 2018, the Chinese yuan was added to the index as a sixth currency.
The price of the US dollar index has fluctuated over its history, reflecting changes in global economic conditions and monetary policy. The index reached a peak of 164.72 in February 1985, due to high US interest rates and strong economic growth, and a low of 71.33 in March 2008, at the height of the global financial crisis.
Live Chart
What Moves The US Dollar Index?
- Interest rates: Higher interest rates generally lead to an increase in demand for US dollars. When interest rates in the US rise, it becomes more attractive for foreign investors to hold US dollar-denominated assets such as bonds, stocks, and real estate. The US dollar rises as a result.
- Inflation: Higher inflation can decrease demand for US dollars, as it reduces the purchasing power of the currency. In addition, high inflation rates can lead to concerns about the stability of the economy, which can cause investors to sell off US dollar-denominated assets and seek safer investments in other currencies. This can contribute to a decline in the value of the US dollar. Note, the best brokers show the US dollar index adjusted for inflation.
- Economic growth: Stronger economic growth in the US can lead to an increase in demand for US dollars, as investors seek to invest in growing markets. This increase in demand for US assets can lead to an increase in demand for US dollars, which can cause the value of the US dollar index to appreciate relative to other currencies.
- Geopolitical events: Political or economic instability in other parts of the world can lead to an increase in demand for US dollars as a safe haven currency. In times of geopolitical instability, investors often become more risk-averse and may look to shift their investments to safer assets, such as those denominated in US dollars. This increase in demand for US assets can lead to an increase in demand for US dollars, which can cause the value of the US dollar index to appreciate.
- Trade balances: A trade deficit can put downward pressure on the US dollar, as it suggests a greater supply of US dollars in global currency markets. As a result, the value of the US dollar index may decline.
- Central bank policy: Actions taken by the Federal Reserve, such as changes in interest rates or the implementation of quantitative easing, can have a significant impact on the value of the US dollar index.
Trading The US Dollar Index
The US dollar index can be traded through various vehicles at the top brokers, including CFDs, futures, options, and ETFs.
To start trading the US dollar index at online brokers:
- Choose a broker: You will need to find a trading broker that allows you to trade the US dollar index. Among the most popular US dollar index brokers in the UK is Pepperstone, an FCA-regulated firm that offers average spreads of 6 pips on the USDX alongside 1:5 leverage.
- Analyse market conditions: Before making a trade, analyse current market conditions and any factors that may impact the price of the US dollar index, such as tracking economic indicators, monitoring central bank policy, or assessing geopolitical events. The top US dollar index brokers offer interactive daily, weekly, monthly and long-term 20+ years charts with historical data and news streams that provide insights to help with forecasts and predictions today.
- Place a trade: The top US dollar index brokers offer trading from charts and graphs on popular platforms like MetaTrader 4. Traders can set stop loss and take profit orders to limit their risk exposure.
Note, the US dollar index is not regulated in the same way as individual stocks or other securities. However, futures contracts that are used to trade the US dollar index are regulated by the Commodity Futures Trading Commission (CFTC) in the United States. The CFTC is responsible for regulating the futures and options markets, including setting rules designed to protect investors and maintain the integrity of the markets and its prices.
UK traders should also sign up with FCA-regulated brokers for additional peace of mind. This should mean sensible restrictions on retail leverage, negative balance protection, plus access to compensation should the brokerage go bankrupt.
Benefits Of US Dollar Index Trading

CMC Markets, for example, offers US dollar index trading from 00:00 – 22:00 GMT, Monday to Friday. The USDX can also be traded through futures contracts on the Intercontinental Exchange (ICE) exchange. The trading hours for the US dollar index futures symbol on ICE are Sunday: 6:00 PM ET to 5:00 PM ET Monday, Monday – Thursday: 6:00 PM ET to 5:00 PM ET the following day, Friday: 6:00 PM ET to 5:00 PM ET Sunday.
Risks Of US Dollar Index Trading
Cons of online trading at US dollar index brokers include:
- High volatility: The US dollar index can be highly volatile to economic or geopolitical events, leading to unexpected price movements.
- Technical analysis challenges: Using past market data to predict future price movements can be challenging with the US dollar index due to the complex nature of the basket of currencies it tracks.
- Economic factors: The US dollar index is heavily influenced by economic factors, such as interest rates and inflation, which can be difficult to predict and analyse accurately.
- Geopolitical risks: Political or geopolitical events impact the US dollar index, making it difficult to anticipate and respond to sudden changes in the market.
- Margin requirements: Trading the US dollar index through derivatives often require traders to post margin, which can increase the risk of large losses.
Bottom Line On The US Dollar Index
The US dollar index is widely followed and is often used as a benchmark for measuring the strength of the US dollar. Traders should consider their financial goals and risk tolerance before investing, and stay informed of economic and geopolitical events that could impact the value of the USDX.
