Best Trading Platforms 2021

Do you want to buy shares of stocks like Apple (AAPL), Facebook (FB), Netflix (NFLX), or Tesla (TSLA)? If so, you’ll need to set up a trading account with an online broker.

Every stock trading platform is unique. And now — with every broker offering $0 stock and ETF trades — deciding which one to use comes down to differences in the overall trading experience. Investment options, trading tools, market research, beginner education, customer service, and ease of use are all factors investors should consider when choosing a broker.

Having led these annual reviews for the past 11 years, I have seen the industry evolve firsthand. I placed my first stock trade when I was just 14 years old. (It was Starbucks.) Today, at 34, my lifelong tally of trades is more than 2,500.

I geek out over every aspect of the trading experience, which is why our review process is so exhaustive. This year we measured more than 250 individual variables. I couldn’t have done this alone, though. Big thanks to my teammates Steven Hatzakis, Jessica Hoelscher, and Joey Shadeck, along with the rest of our awesome editorial staff.

Other Trading Platforms

In addition to our top five trading platforms for 2021, we reviewed six others: Merrill Edge, Firstrade, Ally Invest, TradeStation, Webull and Robinhood. Here are our high-level takeaways for each. To dive deeper, read our reviews.

Merrill Edge — Merrill Edge offers $0 trades with industry-leading research tools (especially ESG research) and excellent customer service. Better yet, for current Bank of America customers, Merrill Edge’s Preferred Rewards program provides the best rewards of any bank broker we tested in 2021.

Firstrade — While Firstrade is easy to use and terrific for Chinese-speaking investors, its overall offering struggles to stand out against brokers who also offer $0 stock trades.

Ally Invest — For current Ally customers looking to invest in stocks, Ally’s universal-accounts experience and easy-to-use website is a convenient solution.

TradeStation — 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.

Webull — Webull offers a unique community experience and easy to use trading platforms that will satisfy most young investors. However, for everyday investing, Webull lacks the trading tools and features to compete with industry leaders who also offer $0 stock and ETF trades.

Robinhood — Robinhood used to shine thanks to its easy-to-use mobile app and $0 trades. However, today, all of the largest online brokers offer free stock and ETF trades. As a result, it is much more difficult for Robinhood to outduel the competition.

2021 Industry Awards

For the StockBrokers.com 2021 Review, all online broker participants were assessed on 256 different variables, with 2,816 data points collected in total. Here are the 2021 main category, secondary category, and industry award winners. Here’s how we tested.

What is the best stockbroker for beginners?

Based on over 30 variables, the best stockbroker for beginners is TD Ameritrade. Alongside paper (practice) trading, TD Ameritrade offers the largest and most diverse selection of educational content. Highlights include over 200 videos, progress tracking, quizzes, and over 100 monthly webinars, among others.

Which online trading platform is best?

Online trading platforms come in one of three forms: desktop (download), web (browser), and mobile (app). After testing 11 brokers and collecting 2,816 data points, we found that TD Ameritrade has the best desktop trading platform, E*TRADE has the best web trading platform, and Fidelity has the best stock trading app.

Who are the top 10 brokerage firms?

The top 10 brokers in 2021 can be ranked by total assets under management, or AUM, as follows:

What is the most profitable trading platform?

The most profitable trading platform for you depends on your needs — whether you’re a day trader, active investor, or passive investor focused on the long term. TD Ameritrade is our top all-around pick for 2021; with multiple platforms for desktop, web and mobile, it’s accessible for all types of customers.

People often mistake trading platforms — like Robinhood or TD Ameritrade’s thinkorswim — for companies that place trades for you; in reality, these platforms are meant for self-directed trading (though they may offer educational tools and materials). If you’re looking for hands-on guidance with your investments, you can search for a trusted financial advisor on investor.com.

It bears noting that trading profits are never guaranteed; for every potential reward there is an equal amount of risk.

Which online broker has the lowest fees?

When it comes to buying stocks online, our research found Fidelity has the lowest fees overall. Fidelity is the only online brokerage to offer $0 stock trades without profiting from the industry practice of payment for order flow, or PFOF. In a world where every online broker offers free stock trades, hidden costs matter.

What does a stockbroker do?

There are two types of stockbrokers. Online stockbrokers or companies like TD Ameritrade and Fidelity allow you to buy and sell stocks. Traditional stockbrokers — who are individuals — buy and sell stocks on behalf of clients. Traditional stockbrokers often work for corporations, as opposed to individual investors.

If you are looking to buy and sell stocks on your own, you are looking for an online stockbroker. When you open an account with a regulated brokerage, you can deposit money and make investments in the stock market.

If you want someone to manage your money for you, you might benefit from looking for a Registered Investment Advisory on sites like investor.com.

Should I hire a stockbroker?

It depends on your needs. If you want to handle your own investments, there’s no need to hire an individual stockbroker; opening a free brokerage account with a broker such as TD Ameritrade provides you with the services needed to trade in the stock market, usually for free or for a small commission per trade.

On the other hand, if you want someone to manage your money for you, then you may consider hiring a financial advisor for a fee. Financial advisors can buy and sell stocks, mutual funds, ETFs and other financial assets for you based on your financial goals and risk tolerance. Our sister site, investor.com, ranks the best financial advisor firms in the United States.

Summary

To recap, here are the best trading platforms overall for 2021.
