StoneX Trading Spread Betting Review

Updated on 23 Sep 2026: City Index renamed its UK brand StoneX Trading on 28 August 2026, so the review now uses the new name throughout. The review moved to a new web address, and the old City Index review address now forwards to it. The opening gains a sentence recording the new name and the date. The ownership answer now gives the date the brand changed. No score, rank or spread figure changed. Earlier: Updated on 23 Sep 2026: Every claim was checked against primary sources on 22 and 23 September 2026, and a large amount of text was removed, including passages that repeated what other pages own and sentences telling a reader which account to choose. The ownership section now records that City Index’s UK site redirects to the StoneX site, which names the business StoneX Trading. A definition of spread cost, app test results, a 2-minute phone support response and demo account terms were added. Earlier: Updated on 22 Sep 2026: Broker facts were re-read at City Index’s own UK pages and the FCA register on 22 Sep 2026, including the demo terms and the platform list, now Web Trader, the StoneX Trading app and TradingView. The margin note now uses the Mon 21 Sep 2026 New York close levels, and the old average wording was renamed the average of the brokers that publish one. Earlier: Updated 19 Sep 2026. This review gains a new section answering whether you can trust City Index, who owns it, what happens to your money if the firm fails and how long withdrawals took in our test, each with its sources and the date we read them, 19 September 2026. The FCA register section now opens with the question of whether City Index is regulated. The byline now credits David Levy as fact-checker, and a sentence noting that City Index also offers CFDs links to our comparison of the two products. No score, rank or spread figure changed. Earlier: Updated 18 Sep 2026. We changed how we read spreads: we now read each broker’s own UK site and record what kind of figure it publishes, average, typical, fixed, target or minimum. The cost section, the verdict and the pros and cons now follow what StoneX Trading publishes. No score or rank changed. Earlier: Updated 5 Sep 2026. Two changes on the day. First, a section inviting readers who have traded with StoneX Trading to tell us what a new customer should know now sits before the FAQ: a rating, how long they have traded, the markets, one thing to know, and their consent. Submissions are read by the team, only reviews we can verify are ever published, and none are published yet; nothing entered there appears on this page. Second, a head-to-head against CMC Markets now sits under the one against our ranking neighbours. That account does not sit either side of this one in our ranking, readers ask for the comparison and the ranking never produced it, and every cell comes from the same data and renders the same nine rows. No figure changed. Earlier: Updated 3 Sep 2026. Three changes on the day. First, a cost band now opens the page: what a spread bet costs at your stake and bet count against the brokers’ average, computed from the same harvest as the spread table further down. Second, the FCA register entry for the authorised firm was re-read and captured, and the capture sits under the section on who you contract with, beside the licence list; the rail’s section list was cut to the sections readers use. Third, the page moved onto the new review layout: a head-to-head against the two accounts either side of it in our ranking, a dated testing log built from the August datasets, a licence list, a per-bet cost tool on the spread table, and a section carrying the third-party ratings read from the platforms themselves, each with the date it was captured. No spread figure, score or rank changed. Earlier: Updated 30 Aug 2026. Four dated tests were added and none was on the page before: a support question timed to first response, an account opening timed to approval, a withdrawal with its fee and arrival, and both store builds of the app driven on an iPhone and a Pixel. The page also gains City Index’s own median fill and its demo terms, and it now says that the app is published in the stores under the StoneX name rather than the brand you searched for. The sentence saying we have published no assessment of how these platforms perform is retired. No spread figure, score or rank changed.
