Interactive Brokers has been named Best US Broker for 2025 by DayTrading.com, recognizing its long-standing commitment to US traders, ultra-low margin rates, and global market access at minimal cost.
IBKR is one of the most respected and trusted brokerages and is regulated by top-tier authorities, so you can have confidence in the integrity and security of your trading account.

TWS’s learning curve is steep, and beginners may find it challenging to navigate the platform and understand all the features. Plus500's web platform is much better suited to new traders.

eToro USA Review

Should You Choose A Broker With A Large Client Base?

In our experience, opting for a broker with a substantial client base comes with several key advantages:

Trust & Reliability: Our investigations found that larger brokers are often heavily regulated by ‘green tier’ bodies in DayTrading.com’s Regulation & Trust Rating, enhancing security and investor protection. Interactive Brokers is a great example, with over 3.5 million clients and licenses from over 10 respected regulators.
Extensive Asset Selection: Our tests show that the biggest brokers typically offer a wider range of tradable assets to help you build a diverse portfolio, from stocks and funds to currencies and derivatives. Just look at eToro – it provides over 7,000 instruments to its more than 38 million customers.
Better Resources: More clients typically means access to comprehensive educational tools and community insights, making them attractive options for newer traders. XTB demonstrates this in abundance with a well-written suite of training articles for its over 1 million traders.
Continuous Platform Innovation: We’ve seen that brokers with more users generally invest in improving their platforms, ensuring cutting-edge technology and features to retain their large client case. Plus500 is a prime example of this, seriously upgrading the usability and features of its mobile app and web trader in the years we’ve been evaluating it.
Greater Liquidity & Faster Execution: High trading volumes can lead to smoother order execution and better pricing, which are vital for active trading styles like day trading. IG remains a great option in this regard, providing 0.014-second average execution speeds to its hundreds of thousands of clients.

For my personal investments, I only choose well-established brokers with large client bases.

Why? Because they typically offer reliability, peace of mind, and user-friendly tools – essential qualities for both beginner and experienced traders.

Does A Bigger Broker Always = A Better Broker?

Not necessarily. While a large client base can indicate trustworthiness, stability, and better features, bigger doesn’t always mean better.

Here’s why:

Higher Fees: Unfortunately we’ve seen that some large brokers charge higher spreads, commissions, or inactivity fees. We don’t like seeing major brokers abusing their position in the market by levying high fees on day traders because we know it can impact their profitability.
Slower Customer Support: We’ve found that a massive user base can sometimes lead to longer response times and less personalized service. Fortunately, the firms that made our toplist performed well during our direct tests of their support.
Less Flexibility: Bigger firms may not cater to more niche day trading strategies like scalping, provide personalized account features, or such generous leverage terms that active traders may be seeking.
Marketing Over Substance: To our annoyance, some large brokers like Robinhood appear to invest heavily in advertising rather than platform improvements or user experience. Where this is the case, we lower their ratings.

In conclusion, it’s always best to compare brokers based on your specific needs – not just size alone.
