Capital Index

Founded in 2014, Capital Index operates under the regulation of the FCA (UK) and the Securities Commission of the Bahamas (SCB).

 The broker focuses on MetaTrader 4 (MT4) trading and offers a selection of CFDs on forex, indices, commodities, and shares. There are several account types available, each tailored to different trader profiles, and the onboarding process is relatively quick. Retail leverage is capped at 1:30 in the UK and EU, while higher leverage is available for professional or non-EU clients.

Platform access is limited to MT4, which will suit traders who are already comfortable with that environment—but those looking for more modern or feature-rich platforms may find the offering a bit dated. Capital Index also provides basic educational tools and market updates, but these are relatively modest compared to brokers that invest heavily in trader support.

We found the account setup process to be fast and straightforward. During testing, execution on MT4 was stable, and the platform performed without technical issues across desktop, web, and mobile. We also liked the clean, no-frills client portal and the broker’s focus on simplicity—Capital Index offers a clutter-free experience that’s easy to navigate.

For traders who rely on MT4 and don’t need a suite of research tools or educational content, the platform does the job. Support was responsive, and the broker provides negative balance protection and segregated funds, which adds a layer of security for clients across both its FCA and international entities.

Capital Index ranks near the bottom of our TraderGuide leaderboard, mainly because of its uncompetitive spreads. In a trading environment where tight pricing is crucial to long-term profitability, Capital Index makes it harder to stay ahead. Trading is already a tough business—starting off with wide spreads only adds unnecessary pressure, especially for active traders.

Beyond pricing, the overall platform offering feels limited. With only MetaTrader 4 available and a light selection of research tools, there’s not much to support traders looking to improve or diversify their approach. Education content is basic, and more advanced users will likely find the platform’s capabilities too restrictive for modern trading needs.

While Capital Index delivers a stable MT4 setup under trusted regulation, it’s difficult to overlook the lack of pricing competitiveness. In our view, it’s not enough to offer simplicity if the spreads work against your strategy from the start.

If you’re just beginning and value a minimal setup, it might serve as a basic entry point—but for anyone focused on cost-efficiency, trade frequency, or strategy execution, there are better choices. We strongly recommend comparing other brokers in our top rankings on TraderGuide before opening an account.
