Best Online Brokers and Trading Platforms:

Fidelity Investments: Best Overall

Why We Chose It

Fidelity is on a multi-year run as our best overall broker due to its client focused approach. Other brokers are closing the gap, but Fidelity remains our overall pick for investors. In addition to refusing payment for order flow, Fidelity continues to keep costs low, provides exceptional tools to help investors manage and analyze their portfolio, and are always improving the platforms and app to make things easier for the individual investor. One example of this is Fidelity’s cash sweep of uninvested funds into a money market funds to give clients another source of modest returns in their portfolios. Fidelity also has excellent order execution and shares the revenue from the stock loan program back to clients. These features, and Fidelity’s commitment to lowering costs for customers while improving returns, are the key reasons it continues to be our selection for best overall broker.

TD Ameritrade: Best for Beginners

Why We Chose It

TD Ameritrade’s strength in investor education flows naturally to TDA being one of the smoothest introductions to the market for new investors. There are, of course, brokers that do it cheaper or flashier, but TD Ameritrade has the resources, range of offerings, and the support that will help new investors become better over the long-term. Major factors in choosing TD Ameritrade include the expanded learning pathways covering everything from beginning to invest to advanced trading, and the ability to paper trade on the platform without making any commitment. TD Ameritrade makes a very compelling case for being a new investors’ choice to enter the market because it manages to be a comprehensive and robust platform without being overwhelming.

TD Ameritrade: Best Mobile App

Why We Chose It

TD Ameritrade has two apps which together form the best overall mobile app offering. The thinkorswim mobile app is designed to make trading easy for traders to manage existing positions and open new ones. The workflow on the app is intuitive and powerful enough that it is possible to trade solely from the app, potentially bringing about a generation of app-only traders who may never touch the more robust, downloadable platforms. The standard TD Ameritrade app for regular investors, you may find the app superior to the full website as it streamlines the entire experience to the necessities while nesting all the other functions in the app for those who are so inclined.

tastyworks: Best Broker for Options

Why We Chose It

Tastyworks remains very competitive on price when it comes to trading options contracts, but what makes it our pick as the best broker for options traders is the focused tools, education, and platforms it offers. Tastyworks isn’t the broker you start options trading on—it is the one you end up choosing once you’ve decided options trading is all you want to do. Tastyworks is optimized for this task in a way that few other brokers are. Options traders will find all the tools and analysis they need during trading sessions, and they can spend their downtime consuming options related content to get ready for the next session.

Fidelity: Best Broker for Low Costs

Why We Chose It

Over the last year, we have re-evaluated what it means to be our best low-cost online broker. There are online brokers that cost next to nothing to trade on. That was all it took to walk away with this category in the past despite a broker having a limited range of assets, or a lack of useful tools, or a weak trading platform—and potentially all three as long as the price was cheap enough. We’ve adjusted our scoring to look for low-cost in comparison to the value delivered. This approach to the data ended up with Fidelity (our best overall broker) on top, but the winning factors over close competitors were the cash management options on idle cash and the excellent portfolio analysis tools that consolidate outside accounts. If you aren’t going to be trading a large amount of options and you don’t require futures or cryptocurrency, then Fidelity offers you the most bang for your buck.

Interactive Brokers: Best for Advanced Traders

Interactive Brokers (IBKR) remains our pick for advanced day traders, continuing another multi-year run. In this category, we assume advanced day traders are willing to bring third party solutions to make up for the gaps in back testing and automation in exchange for the wider access that Interactive Brokers provides in terms of international exchanges, an extensive selection of stocks on the easy-to-borrow list, and incredibly low margin rates. Cryptocurrency inclined advanced day traders are now able to engage in direct coin trading as of September 2021, and everyone else will find that Interactive Brokers has all the assets, reach, and tools they need as well as a very attractive margin rate.

Interactive Brokers: Best for International Trading

Interactive Brokers is in no danger of being unseated as our pick for best online broker for international trading. Interactive Brokers dominates the scoring in this category simply by virtue of its access to 135 exchanges in 33 countries all accessible through a single account. On top of this, Interactive Broker gives you the ability to trade 23 currencies in 115 different pairs in addition to the broker’s robust order selection and trading tools. This breadth and depth combines to enable traders to set up positions across markets and asset classes in a way that no other broker can currently match.

Charles Schwab: Best for ETFs

Schwab is a full-service investment firm that ranks highly across many of our scoring categories, let alone for ETFs. Schwab often sits top five and frequently top three throughout our categories, getting edged by slightly more focused offerings. When it comes to ETFs, however, Schwab continues to be our pick. This is largely on the strength of its ETF screener combined with the general quality of its overall offering, including education around ETF investing and portfolio analysis tools for everyday investors. Schwab makes the process of investing in ETFs simple while still providing excellent research and multi-criteria screening for investors who want that depth prior to making a decision.

What to Consider When Choosing an Online Broker

When you are choosing an online stock broker you have to think about your immediate needs as an investor. Are you a beginner? Maybe you need a broker that has great educational material about the stock market. Do you only have a small amount of money you can put aside to invest? Some online brokers allow for small minimum deposits which can be a great option for those with limited funds. Are you always on the go and in need of a robust mobile platform? Some online brokers have incredible mobile apps delivering nearly all the features that their desktop counterparts do.

Another important thing to consider is the distinction between investing and trading. When people talk about investing they generally mean the purchasing of assets to be held for a long period of time. These types of investments are usually made to reach a retirement goal or to put your money into assets that may grow faster than it would in a standard savings account accruing interest. Trading, on the other hand, most commonly involves the buying and selling of assets in short periods. Trading is generally considered riskier than investing.

All of these factors must be considered before choosing an online broker. Do you want to trade or invest? Do you want a great mobile app to check your portfolio wherever you are? What types of assets are you looking to invest in? Answering these questions is not always easy.
