The StockBrokers.com best online brokers 2021 review (11th annual) took three months to complete and produced over 40,000 words of research. Here's how we tested.
When it comes to free stock trading in 2021, investors need to look beyond the price of stock and ETF trades. Why? Because all brokers offer free trades. However, not all brokers have excellent education, a great trading platform, or robust market research. Also, most brokers accept payment for order flow (PFOF), a hidden fee that generates over $1B each year in profits for the industry.
For our 2021 Annual Review, we scored 11 different online brokers that offer free trading. To assess each platform, we tested well over 100 features, broke down miscellaneous account fees, and researched each firm's order execution practices.

TradeStation - Open Account
Promo Offer: Commission-Free Trades on Stocks, ETFs & Options Trades
As a trading technology leader, TradeStation supports casual traders through its web-based platform and active traders through its award-winning desktop platform, all with $0 stock and ETF trades. Like its other active-trader focused competitors, TradeStation lacks in its offering of fundamental company research for casual investors. Education is also a mixed bag, making it just an "ok" choice for beginners. Read full review
Webull - Open Account
Current Offer: $0 commission trading for online stocks, ETFs, options, cryptos and more on Webull!
While Webull's mobile app offers more features than Robinhood, it struggles to compete with the extensive amount of trading tools provided by the best stock trading apps. Also, like Robinhood, Webull's top source of revenue is payment for order flow (PFOF), making hidden trading costs a substantial drawback to using the app. Read full review
Robinhood
Robinhood's stock app is very easy to use; however, now that all online brokers offer $0 stock and ETF trades, Robinhood's lack of trading tools and research leaves it a step behind the competition. In addition, Robinhood's top source of revenue is payment for order flow (PFOF), making hidden trading costs a substantial drawback to using the app. Read full review

What is commission free trading?
Commission-free trading means there is no charge for placing a stock or ETF trade. In October 2019, a pricing war led to the full-service brokerages cutting their stock and ETF commissions to $0 to compete with free trading platforms such as Robinhood.
How do brokers make money on commission free trades?
For startup brokers such as Robinhood and Webull, payment for order flow (PFOF) is the primary way they make money. Meanwhile, for larger full-service brokers such as Fidelity and Schwab, their largest revenue source comes from sweeping the idle cash sitting in customer accounts into subsidiary banks each night.
More details: When online brokers sweep uninvested cash overnight into their subsidiary banks, they earn a tiny bit of interest. Brokers claim they share this with their customers, but the reality is, most keep the majority of interest for themselves. While it may not seem like much, earned interest adds up when conducted across millions of accounts and billions in idle cash.
What is the best free trading platform?
The best free trading platforms offer $0 stock and ETF trades, easy to use trading apps, quality market research and education, and a diverse selection of trading tools. Our top picks for free stock trading in 2021 are Fidelity, TD Ameritrade, Interactive Brokers, E*TRADE, Charles Schwab.
