Choosing the Best Online Brokerage
When looking for a new online broker, make sure you meet your most important needs as an investor. Are low-cost trade commissions most important? What about customer service, the trade platform, mobile trading, active trading, or a community to trade alongside? With many brokers specializing in different areas, it is vital to evaluate and compare all the possibilities.
Here is a list of the most important factors to remember when selecting an online brokerage:
- Trading Costs - When trading stocks online, it is important to understand what the costs are to place buy or sell orders. Most online brokers charge a flat rate to buy and sell. That said, other miscellaneous day trading costs can be incurred for direct routing fees or accessing market data. If you are investing in a retirement account, it is important to avoid choosing a broker that charges annual IRA fees.
- Trading Tools - One of the most common misconceptions newer investors have is that low trading costs are the most important consideration. This couldn't be further from the truth. Having access to a fully featured desktop-based or web-based trading platform can make a big difference, especially when conducting technical analysis.
- Investment Products - Are you only trading stocks online, or are you interested in ETFs, mutual funds, options, futures, and forex too? In the United States, different regulations are required for brokers who support more complex asset classes. Beyond trading different assets classes, having access to online banking and advanced order types, such as conditional orders, are also considerations.
- Mobile Trading - Managing a stock brokerage account on the go is certainly important for traders who travel and frequently use their smartphones. While nearly all online brokerages offer mobile trading apps, not all are created equal. Features can vary dramatically.
- Customer Service - 24/7 support is important to some investors, while others may just want to use online chat during regular market hours or receive an email back within one business day. Having access to quality customer support can really be the cherry on the top of a great client experience, especially during market crises like a flash crash.
- Stock Analysis - Conducting fundamental research is critical to successful long-term investing. SEC filings, short interest, corporate debt levels, earnings growth, and more are all examples of important criteria to be investigated during fundamental investment research.
- Regulation - Stock brokers based in the United States and governed by US law will be regulated by the SEC and must be members of FINRA and SIPC. The easiest way to verify whether your online brokerage is regulated is to scroll to the footer of their homepage and read their disclosures. Using the FINRA broker check tool is another easy way to verify proper compliance.
- Banking Services - Online brokerage accounts are not limited to just stock trading. Instead, customers can take advantage of banking services offered by full-service brokerages (see the list above for three great examples). Some online brokers offer checking accounts, savings accounts, credit cards, and more with deposits of up to $250,000 backed by the FDIC.
- Account Security - Fortunately, today’s investors don’t have much to worry about when it comes to account security as long they choose a brokerage that is large, well known, and properly regulated. Reference our list above or below for a sampling. Every website should be secured with SSL encryption, and client data should be stored in secure servers. Dual-factor authentication and Touch ID are other security protocols quickly growing in popularity.
- Order Execution - It is important to understand how your order is routed and executed. Make no mistake, there is a wide variation between quality execution and poor execution. Unfortunately, most online stock traders can't tell the difference.
- International Trading - The US stock market is the most respected in the world. If you are living in the US and want to trade internationally, or are living abroad and want to trade stocks online with a US-regulated brokerage, you must do your research beforehand and find a broker that supports your requirements.
Best Trading Tools
Based on 59 different variables, here is a summary of the top five brokers for stock trading tools and trade platforms.
- TD Ameritrade - Scored 100%
- TradeStation - Scored 93%
- Fidelity - Scored 93%
- Charles Schwab - Scored 91%
- Interactive Brokers - Scored 89%
To trade online successfully, some investors rely purely on their trading tools. Today’s trading platforms are not only web based, but also desktop based, and are becoming increasingly mobile based as well. Advanced charting, options tools, screeners, hotkeys, virtual trading, watch lists, ladders, Level II quotes, and back testing are just a sampling of the functionality brokers make available to their customers.
Over the years, I have learned it is not just the trading tools that separate brokers, but the design, depth, speed, and overall execution of delivering the ultimate trading experience.
Over the years, I have learned it is not just the trading tools that separate brokers, but the design, depth, speed, and overall execution of delivering the ultimate trading experience. This is where brokers such as TD Ameritrade’s thinkorswim and TradeStation really excel. After spending hundreds of hours on both desktop platforms, we give thinkorswim the edge, thanks to its modern feel and outstanding trader tools; however, both platforms execute so well that it truly comes down to personal preference. Die-hard fans exist for both, and either one is a great choice for seasoned active traders.
Behind thinkorswim and TradeStation, Fidelity’s Active Trader Pro and Schwab’s StreetSmart Edge are two desktop platforms worth looking at closely. Active Trader Pro and StreetSmart Edge have one distinct advantage over thinkorswim and TradeStation, and that is ease of use. While these platforms do not offer the same depth of trading tools, historical data, chart studies, etc., both are very well designed and user-friendly. In some respects, their balance of power and design make them a better fit for certain traders.
Unfortunately, not all active trader platforms are free to use or available to all customers. For example, to gain complete access to Fidelity’s Active Trader Pro offering, 36 trades or more must be placed in a rolling 12-month period. Similarly, E*TRADE Pro requires at least 30 trades per quarter or $250,000 in assets. Finally, Lightspeed charges $100 per month for access to its flagship platforms if certain minimums are not met. Platform fees and minimums are set in place to control costs, and while these serve simply as examples, investors should be aware of them if they are considering an online broker based solely on its platform.
Investors who prefer a web-focused experience have a choice of many great browser-based platforms. Our top pick again this year, OptionsHouse by E*TRADE, combines the best of both worlds: ease of use with fantastic trading tools. The platform is just “ok” for equities trading, but is terrific for options trading. See: Best Brokers for Options Trading.
Ultimately, TD Ameritrade takes the overall No. 1 spot for Platforms and Tools because it offers investors fantastic trading experiences on desktop and on browsers. Trade Architect (browser) appeals to newer and intermediate investors, while thinkorswim (desktop) is built solely for seasoned active traders. The icing on the cake? Both platforms require no minimums or fees for access and use. All customers have access.
Before selecting a broker based on its platforms and tools, take time to read our online broker reviews, narrow your search to two or three brokers, compare their offerings, then make a decision. Start with questions like: What specific trader tools must I have to trade successfully? Will I reach the minimums to maintain fee-less, consistent access throughout the year? Do I prefer a more user-friendly browser-based platform or a more advanced trader-focused desktop platform?
Best for Stock Analysis
Based on 60 different variables, here is a summary of the top five brokers for stock research:
- Fidelity - Scored 98%
- Charles Schwab - Scored 97%
- TD Ameritrade - Scored 97%
- E*TRADE - Scored 92%
- Merrill Edge - Scored 90%
It is not surprising that the largest, most publicly known online brokers excel, and all vie for the top spot for research. With larger client bases and higher commission costs, high-quality research is expected.
Comparing apples with apples, all five brokers are fairly similar. They all use Morningstar as their primary provider for Exchange Traded Funds (ETF) and mutual fund research, all of them offer a slew of data and graphs for researching stocks, and all offer fixed-income research. Slight differences begin to show only when you assess specifics such as total third-party research reports available for equities, for example Apple (AAPL). In that category, the title goes to Fidelity, with 12 total reports offered, followed by Charles Schwab with eight, and TD Ameritrade with seven.
While any of these brokers will more than satisfy most investors’ appetites, deciding on a winner based on checklists alone is not enough.
While any of these brokers will more than satisfy most investors’ appetites, deciding on a winner based on checklists alone is not enough. Quality and design matter just as much as quantity, not to mention the fact that many brokers will go “above and beyond” to differentiate themselves.
Fidelity, which earned our No. 1 spot again this year, stands out for its 12 equity research reports and fantastic stock comparisons, allowing customers to compare up to five stocks at once with 21 different metrics. Fidelity also distributes high-quality market analysis and personal finance education through its Fidelity Viewpoints weekly distribution. What excites us most about Fidelity is its fully responsive (mobile friendly), carefully laid out research area. Content flow and personalization are at the heart of the experience, which is unlike any other broker in the industry.
Charles Schwab, on the other hand, offers customers its own proprietary A – F ratings, called Schwab Equity Ratings, for some 3,000 US stocks. Even more impressive, Schwab boasts a full lineup of 26 in-house experts who provide numerous articles, known as Schwab Insights, on a variety of market topics throughout each week. Some experts, such as Chief Investment Strategist Liz Ann Sonders, can often be seen on TV discussing the market. Schwab also provides the best video experience out of all the brokers, thanks to its market updates and Schwab LIVE events.
Not to be outdone, TD Ameritrade won our Best New Tool award in 2017 for the earnings analysis tool offered on its thinkorswim platform. TD Ameritrade also offers what it calls Social Signals analysis for individual equities. Using proprietary algorithms, the Sentiment Score shows what percentage of tweets are positive and displays other relevant metrics. Additionally, in the social realm, TD Ameritrade analyzes data from its six million retail customers to create what it calls the Investor Movement Index (IMX), which displays and analyzes the sentiment of its retail investors’ portfolios.
All in all, when it comes to researching stocks, ETFs, mutual funds, and fixed income, any top five broker is going to provide an excellent experience for investors. With such similar offerings, it’s the unique experience, features, and functionality that differentiate the brokers.
Best for Investment Products
Based on 40 different variables, here is a summary of the top five brokers for investment products:
- Interactive Brokers - Scored 96%
- TD Ameritrade - Scored 91%
- Charles Schwab - Scored 89%
- Fidelity - Scored 88%
- E*TRADE - Scored 87%
Investing covers a global spectrum, from investing in international equities to trading forex to purchasing US treasury bonds. To understand the true range of offerings, StockBrokers.com has focused on all the broad investment channels down to the specific order types each broker offers. In the process, we compare 40 different variables.
Starting with the US, services such as complex options trading, fixed income, and direct market routing are all very common. Other services, such as commission-free ETFs, are still growing in the industry. Just 46% of brokers offered commission-free ETFs heading into 2018, with TD Ameritrade leading the way (296). Every broker in the industry supports weekly options, and only four brokers – Capital One Investing, Firstrade, Just2Trade, and Merrill Edge – don’t yet support complex options. On the flip side, only 46% of brokers offer direct market routing for options.
As far as order types go, it is an industry standard to support market orders, limit orders, stop orders, and after-hours trading. Even more advanced order types such as trailing stops, OCO, OTO, OTOCO, and multi-contingent orders are supported by more than half the industry. The least common order type is algo, offered by less than half the industry. The leader overall is Interactive Brokers, which offers customers an arsenal of 63 different order types, some of which are exclusively designed for institutional investors.
Looking at international trading, Fidelity and Interactive Brokers are, by a wide margin, the two best choices.
Looking at international trading, Fidelity and Interactive Brokers are, by a wide margin, the two best choices. Fidelity offers its customers access to trading equities in 25 countries. Interactive Brokers offers less equities support – in “only” 18 different countries; however, all investment types considered, the total comes to 26 countries and over 120 market centers. Both brokers also make it a seamless trading experience, allowing customers to trade from their primary account. Charles Schwab (12 countries in which to access equities) requires a separate account to be opened to place trades.
Plenty of options are available for futures trading, while forex trading is scarcely supported. Just two brokers, TD Ameritrade and Ally Invest, offer forex trading to US customers, and just over half the industry offers futures trading.
All variables considered, Interactive Brokers is the top choice for the largest offering of investments in 2017, earning 96% of the possible points. TD Ameritrade and Charles Schwab follow in second and third places, earning 91% and 89%, respectively.
Best for Banking Services
Based on 13 different variables, here is a summary of the top five brokers for online banking services:
- Merrill Edge - Scored 99%
- Capital One Investing - Scored 96%
- Charles Schwab - Scored 94%
- Fidelity - Scored 77%
- Ally Invest - Scored 76%
For full-service brokers, the client experience goes beyond just trading. Customers of Merrill Edge, Capital One Investing, Charles Schwab, Ally Invest, and Fidelity all fall under this category, meaning banking services are also offered.
To determine which broker is the best for banking, we dived in head first and explored all the potential services: checking accounts, savings accounts, debit cards, credit cards, and mortgages. We then looked at specialty offerings such as mobile check deposit, debit card ATM fee reimbursement, and no-fee banking. Lastly, the total number of branch offices was factored in, as access to local branch offices is just as important as managing an account online.
It should be no surprise that our #1 choice is Merrill Edge, whose parent company is Bank of America.
It should be no surprise that our #1 choice is Merrill Edge, whose parent company is Bank of America. With a Financial Solutions Advisor (FSA) located in 2,167 out of a total 4,480 locations, Bank of America has, by far, the largest network.
Bank of America really shines with its rewards program, Preferred Rewards, which offers customers with certain account thresholds a range of benefits. The first tier, Gold, requires at least $20,000 in combined assets between Bank of America and Merrill Edge, while the top tier, Platinum Plus, requires at least $100,000 in total assets. Benefits include boosts to money-market savings, credit card cash back bonuses, free trades with Merrill Edge, and more. All in all, there isn’t a better marriage of brokerage and banking than Merrill Edge and Bank of America.
Alongside Merrill Edge’s parent company, Bank of America, another well-recognized brand is Capital One Investing, whose parent company is Capital One. Next to Bank of America, Capital One is the only other bank to offer every service type: retail locations, checking accounts, savings accounts, debit cards, credit cards, and home mortgages. Capital One is best known for its credit cards, and like Bank of America, its customers enjoy the benefits of universal login for easy access to all their accounts.
Together with our ranking, we present highlights from the rest of the full-service brokers. Fidelity has one of the best cash rewards credit cards on the market, with its 2% Fidelity Investment Rewards Visa Card (Fidelity cut its ties with American Express in early 2016). Of the remaining brokers, Charles Schwab is the only one to offer home mortgages. The list goes on and on.
When it comes to banking and brokers, the great news is that investors have multiple options from which to choose. Full-service brokerages generally do a very good job of catering to the specific needs of their customers, and provide a well-rounded offering. This is especially true for customers who already do their banking with Bank of America, Capital One, or Ally; the move to add investing as an additional service is just a few clicks away.
Best for Customer Service
Based on 260 phone tests over ten weeks, here is a summary of the top five brokers for customer service (view infographic):
When assessing customer service, one phone call is not enough. To gauge the quality of support properly, multiple tests across every channel must be conducted. Here at StockBrokers.com, we are proud of the fact that our testing is respected as the most rigorous in the industry.
To ensure the highest quality testing data, we partner with professional private shopping group Confero.

With customers such as Coca Cola and Shell, Confero understands how to read between the lines and identify truly superior customer service. Using our StockBrokers.com industry-specific templates, Confero made 260 phone calls to branch offices and support numbers across the United States.
This year, TD Ameritrade was once again able to take the No. 1 spot overall, edging out Fidelity. Merrill Edge has been an extremely consistent performer, finishing third in 2018, second in 2017, first in 2016, and second again in both 2015 and 2014. The consistency and ability of TD Ameritrade’s support reps to repeatedly deliver an A or A+ experience is truly impressive.
