Fidelity takes the top spot on our 2019 broker roundup with a winning combination of services, tools, and value. Last year, Fidelity focused on improving its infrastructure and reliability so it could avoid the crashes that plagued online brokers in 2018. Another improvement was making their Active Trader Pro platform available to all customers rather than requiring a certain number of trades to use. Fidelity improved the order entry interface to avoid the most common errors made by customers.

Fidelity also received awards for Best for Beginners, Best Stock Trading Apps, Best for ETFs, Best for Penny Stocks, Best for Roth IRAs, Best for IRAs, Best for International Trading, and Best Web Trading Platforms. 

Pros

  • Excellent trade executions, generating price improvement for stock and options trades

  • ETF research center includes tools to show you which stocks compose the fund

  • All customers have access to Active Trade Pro

  • Fees are on the low side and are easy to understand

Cons

  • Accessing all of Fidelity's tools may require you to use multiple platforms

  • Finding a particular tool can be difficult on Fidelity’s extensive menu system

  • If you are not a U.S. citizen or resident, you cannot open an account

4.3
  • Account Minimum: $0
  • Fees: $0.005 per share

Interactive Brokers ranks second overall in our 2019 review due to its wealth of tools for sophisticated investors. The firm makes a point of connecting to any electronic exchange globally, so you can trade equities, options, and futures around the world and around the clock, on your desktop or mobile device. Though Interactive Brokers has been adding features to attract more assets and help newer investors, including its own robo-advisory, we recommend that newcomers to trading start somewhere else and grow into their extensive capabilities.

Interactive Brokers also received awards for Best for International Trading, Best for Low Costs, Best for Options Trading, Best for Penny Stocks, and Best for Day Trading.

  • Pricing is on the low end, especially margin rates

TD Ameritrade, one of the largest online brokers, has several platforms to choose from, ranging from their basic website to thinkorswim, which is designed for very active traders. The firm spent the last year streamlining its website and transforming its education offering while bringing over the 3.5 million customers who joined following the acquisition of Scottrade. Given the number of platforms customers can use for research and trading, the sheer number of tools available can be overwhelming. There is an ongoing initiative to streamline the content and platforms, so going forward, it should be easier to find and use the features that you need.

TD Ameritrade also received awards for Best for Day Trading, Best for Options Trading, Best Web Trading Platforms, Best for Beginners, Best for ETFs, Best for Roth IRAs, Best for IRAs and Best Stock Trading Apps.

Cons

  • Commission structure makes them an expensive place to trade

  • Clients may have to use more than one trading system to find all the tools they want

Methodology

Investopedia’s mission is to provide investors with unbiased, comprehensive reviews and ratings of online brokers. Our reviews are the result of six months of evaluating all aspects of an online broker’s platform, including the user experience, the quality of trade executions, the products available on their platforms, costs and fees, security, the mobile experience and customer service. We established a rating scale based on our criteria, collecting over 3,000 data points that we weighed into our star scoring system.

In addition, every broker we surveyed was required to fill out a 320-point survey about all aspects of their platform that we used in our testing. Many of the online brokers we evaluated provided us with in-person demonstrations of their platforms at our offices.

Our team of industry experts, led by Theresa W. Carey, conducted our reviews and developed this best-in-industry methodology for ranking online investing platforms for users at all levels. Click here to read our full methodology.
