- While primarily geared towards experienced traders, IBKR has made moves to broaden its appeal in recent years, reducing its minimum deposit from $10,000 to $0.
Cons

- TWS’s learning curve is steep, and beginners may find it challenging to navigate the platform and understand all the features.

Pros
- The market replay function is a standout feature — you can download tick-by-tick historical data, rewind to any specific date, and interact with it as if trading live, making it genuinely useful for both strategy testing and real-world practice
- Nano contracts — one-hundredth the size of standard contracts on NinjaTrader — allow traders to size positions with precision and manage risk at a much smaller scale, a meaningful advantage for those building positions gradually
- NinjaTrader's ecosystem gives traders access to thousands of add-ons and applications from developers across more than 150 countries, covering indicators, strategies, and custom tools that go well beyond what the platform ships with natively
Cons
- NinjaTrader was acquired by Kraken in May 2025, and while it continues to operate independently for now, traders who value long-term stability may have reservations about how the platform's direction and pricing could shift under new ownership.
- NinjaTrader was fined $250k in 2025 for failing to implement an adequate anti-money laundering (AML) program and for supervisory failures.
- Intraday margin requirements can spike by as much as four times in the 15 minutes leading up to major economic news releases, and may stay elevated for several minutes after volatility subsides — a detail that can catch underprepared traders off guard at exactly the wrong moment.
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.
James BarraHead of Content and Media LeadDoes 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.
