Is StoneX Trading a good spread betting broker?

StoneX Trading is one of my favourite spread betting brokers and was the winner of Best Spread Betting Broker at the Good Money Guide Awards 2025.

That award came when the retail trading business was still called City Index, but it is now StoneX Trading and the core spread betting offering remains very strong. In fact, StoneX Trading still displays the Good Money Guide Best Spread Bet Broker 2025 award on its spread betting pages.

It has also done particularly well in our awards over the years. City Index won Best Trader Tools in 2023, Best Trading App in 2024 and then Best Spread Betting Broker in 2025.

What makes StoneX Trading stand out is that it is a very good all-rounder. There are spread betting brokers that can sometimes beat it on price on individual markets, but StoneX combines competitive spreads with thousands of markets, a very good trading platform, TradingView integration and some genuinely useful tools.

Performance Analytics is still one of my favourite features. Rather than just showing you what you have made or lost, it looks at your trading behaviour and helps you identify where you are making mistakes. If you are an active spread bettor, understanding how you lose money can sometimes be more useful than another trading signal.

Overall, StoneX Trading remains one of the best spread betting brokers for UK traders who want a combination of good pricing, lots of markets and decent trading tools rather than simply choosing a broker based on the tightest headline spread.

Pricing

StoneX Trading doesn’t charge commission on spread bets. Instead, its charge is included in the difference between the buy and sell price.

Current minimum spreads start from 0.5 points on forex, 0.4 points on indices, 0.1% on shares and 1 point on commodities.

Those are competitive headline rates, although, as with all spread betting brokers, the spread you actually pay depends on the market and when you trade it.

If you hold a daily funded spread bet overnight, you will also pay overnight financing. That’s important because financing can become a much bigger cost than the spread if you keep a leveraged position open for weeks or months.

There is also no Stamp Duty or Capital Gains Tax on spread betting profits under current UK tax rules. That’s one of the main advantages spread betting has over conventional share dealing, although tax treatment depends on your circumstances and can change.

Market Access

StoneX Trading lets you spread bet on thousands of markets across shares, indices, forex, commodities and other financial markets.

One of the things I have always liked about City Index’s spread betting offering is the range of shares available. This makes it more useful if you want to spread bet individual companies rather than just trading the FTSE, DAX, S&P 500 and major currency pairs.

StoneX Trading also offers extended-hours trading, including access to pre- and post-market sessions.

That can be particularly useful for US shares because companies often release results outside normal market hours. If Nvidia announces earnings after the closing bell, for example, you don’t necessarily have to wait until the following day’s main session before taking a position.

One thing I would remove from the old review is the claim that City Index offers 12,000 markets and 182 FX pairs. Those were the old figures, whereas StoneX Trading’s current material now simply says thousands of markets.

Platform & Apps

StoneX Trading has one of the better spread betting platforms and gives you several different ways to trade.

Its main Web Trader platform runs in your browser and has customisable workspaces and Performance Analytics. There is also the StoneX Trading mobile app, which won Best Trading App at the Good Money Guide Awards 2025.

You can also connect your account to TradingView and trade directly from TradingView’s charts.

MT4 is available as well for FX, commodities and indices, although personally I think StoneX Trading’s own platform is the better option for most spread bettors.

Performance Analytics remains one of the standout features. It tracks your trading behaviour and decision-making against your goals, while GamePlan gives you a scorecard highlighting strengths, weaknesses and areas you can work on.

This is something I have always liked about the platform. Most brokers are very good at giving you more things to trade. StoneX Trading also gives you tools designed to help you understand whether you are actually any good at trading them.

Customer Service

Customer service is another reason I rate StoneX Trading highly as a spread betting broker.

Spread betting is a leveraged product and, when markets are moving quickly, being able to get help with your account or a trade becomes considerably more important than it is with a straightforward investment account.

StoneX Trading provides online support and live chat alongside its trading platforms.

More importantly, it still feels like a proper trading broker rather than simply an app. That becomes increasingly important as the size and frequency of your trades increase.

If I was putting £5 a point on the FTSE occasionally, customer service probably wouldn’t be at the top of my list. If I was regularly trading £100 a point across several markets, it absolutely would be.

Research & Analysis

Research and trading tools are one of StoneX Trading’s biggest strengths.

The platform includes Performance Analytics, which tracks your trading behaviour and decision-making, and GamePlan, which scores your trading and highlights areas where you could improve.

I’ve always thought this was particularly useful for spread betting because the biggest problem for many traders isn’t finding something to trade. It’s overtrading, increasing position sizes after a loss, cutting winners too early or letting losers run.

Being able to analyse your own behaviour can therefore be considerably more useful than simply being given another buy or sell signal.

You also get the broader StoneX market research and analysis offering alongside the charting and technical analysis tools available through TradingView.

That combination of market analysis before you trade and Performance Analytics after you trade is one of the main reasons StoneX Trading stands out from more basic spread betting platforms – and why it deserved to win Best Spread Betting Broker at the Good Money Guide Awards 2025.
