What’s the first image that comes to mind when you think of a stock broker?

If you’re like most new investors, images of Gordon Gecko in Wall Street may come to mind.  Yet while that image may have been accurate a few decades ago, it’s more accurate to think of the modern-day stockbroker as a computer, rather than someone in a colorful jacket yelling buy and sell orders on the floor of a busy exchange.

But whether it is a computer or a person yelling “sell, sell, sell!”, we need stock brokers to invest (for the most part). 💰

The world of finance is complicated, and the job many people consider a “stockbroker” is more accurately described as a trader. There are traders who trade other people’s money for them, known as broker-dealers. There are also traders who trade for their own firm’s account, known as proprietary traders or hedge fund portfolio managers.

Ultimately, a broker is a person or software platform that allows you to buy or sell stocks, bonds, options, and other securities. When considering your options for different brokers, you should weigh factors like ease-of-use, available research tools, technology like mobile apps, and fee structure.

In this short guide, we will describe some popular brokerages, explain how they work, what you should look for in a broker, and what you can expect to get from them. Let’s start with a few examples.

5 Examples of Online Brokers Platforms and How They Operate

There are different types of brokers, but they mainly fall into these categories or a combination of them: Depending on what type of investor you are or what type of broker you want to be, there are several ways to invest. According to the investment style you choose you can belong to one of the four main categories of brokers:

  •  Full-service broker
  •  Discount broker
  •  Online broker
  •  Robo-advisor

Each of these services has its own set of advantages and limitations—we’ll show you five online broker platforms and provide you with details on how they operate:

1. TD Ameritrade – Best Overall

If you are seeking a top-notch discount broker, then TD Ameritrade can be your best pick.

Also known as TD Ameritrade Holding Corporation (AMTD), this broker provides a full-service option and discount brokerage options with the ability to trade stocks, ETFs, mutual funds, options, futures contracts, retirement investments, and income investments.

Based in Omaha, Nebraska, TD Ameritrade has 11 million accounts and manages more than $1 trillion for its clients. They also charge a simple trading fee of $6.95 per trade.

All in all, the borkerage is one of the most well-rounded in the business—it also allows forex trading on its user friendly platform. You will find more specialized brokers than, but you likely won’t go wrong by choosing TD Ameritrade.

2. Charles Schwab – Most Versatile

Charles Schwab’s platform provides advanced research and trading tools for all kinds of traders.

Charles Schwab is a full-service brokerage firm that offers all kinds of technology and services to every kind of trader. If you are an active trader or need a full-service broker for trading advice, there are multiple levels of account management and investing.

They offer a number of online tools to help their clients make trades on their own, and they provide a guaranteed refund for clients unhappy with their fee-based services.

However, Charles Schwab also pushes investors to use their financial advisors instead of making trades on their own, which can cause investors to lose confidence or change their portfolio too drastically. Essentially, everything active investors need is there, but getting a professional portfolio manager is just a click away.

3. Acorns – Best for Passive Investors

Acorns provides excellent savings tools and advanced trading services for rookie traders.

Acorns is a hands-off investor’s dream. As a brokerage account and savings tool, Acorns takes leftover change and small investments to build a nest egg. It basically uses robo-advisors to help beginner and passive investors make money through their savings.

They charge a $5 fee to start investing and a $1 to $3 monthly fee for account management. For this fee, they manage your money, growing it at a steady pace and can even help you invest it.

Using an Acorns card lets you round up your every purchase to the next dollar and invest the difference. This means that you will invest $0.40 every time you spend $2.60 on a cup of joe—and that stack up over time.

Also, their ETF expense ratios average at 0.10 percent, which is on the cheap side. For an automated investing solution, all this could help college students and beginner investors save some money.

4. E*Trade – Lowest Prices

E*Trade was among the first discount brokers that started providing its services online.

E*Trade was probably the first discount online broker. Many people have seen E*Trade through their outlandish commercials, such as a baby broker advising on investments. E*Trade does contend that trading is that easy through their platinum, and they have a lot of tools and options to help their investors make it simple.

One of the benefits to E*Trade as a brokerage is that they offer robust trading, research, and analysis software—the low prices are a bonus rather than a trade-off.

The brokerage also does not charge commissions on stock and ETF trades, which is a huge boon for day traders. Options are rated at $0.50 to $0.65 per contract, but it depends on trading volume—either way, these are some of the lowest prices you will find among top-tier brokers.

5. Interactive Brokers – Largest Range of Investment

Interactive Brokers’ online broker platform aims to provide its customers with superior trading tools.

IBKR holds over $150 billion in equity from its clients. The brokerage also has very competitive commissions going down to $0.005 per share with a minimum of $1 trades.

With their electronic exchange, Interactive Brokers lets you access options, futures, and equities. There are also several mobile tools available through this broker, but you do not have access to your own investment advisor.

What is a Broker? 🤔

Brokers play the role of a market maker, which means they act as a liaison between buyers and sellers. They either make or take liquidity based on the type of order they place. Brokers “make liquidity” by placing marketable orders and “take liquidity” by placing limit orders.

Brokers are often entire firms rather than a single person. These firms often offer many services including managing money, offering investment advice, and even creating their own financial products like ETFs or mutual funds to sell to their clients. Brokers receive commissions for each transaction and earn interest as account custodians. To help grow their assets under management, brokerage firms often offer signing bonuses for new clients. This bonus makes it a good idea for you to shop around every once in a while to make sure you are getting a good deal.

New technology has not only disrupted the manual buying and selling of orders. Many of the “online brokers” have expanded their discounted platforms beyond just trading to include robo-advisors and related algorithms that expand their offerings into the world of advisory. If you have signed up for an online broker or an app, you may use tools informed by AI rather than a human broker.

To become a broker as an individual, you have to be licensed, and many brokers also get advanced degrees in business, finance, economics or accounting. Certifications also help brokers work in specialized fields or go after high-level positions.

How Brokers and Brokerage Firms Operate? 💡

  •  Brokers can be a single individual or a firm that charges a commission or trade fee for placing buy and sell orders that you submit as an investor.
  •  The term “broker” can also be used interchangeably for a digital broker or online broker that charges a commission to place buy and sell orders.
  •  There are also discount brokers that place trading orders for clients, but they do not provide any investment tips, market intelligence, or 1-on-1 advice.
  •  A “full-service broker” typically includes your own advisor who provides investment tips and solutions for your portfolio, while also executing buy and sell orders for you.
  •  To be a legitimate broker, you must register and be certified through FINRA, and depending on the services you are providing you may need to either register as an RIA or a broker-dealer with the SEC (at least in the United States).

Discount vs. Full-Service Brokers: Weighing Your Options

Discount brokers can execute a variety of orders for their clients, and they typically do not charge as much in commission as a full-service broker. Trades typically cost as little as $5, but you will never spend over $15 on commission fees with discount brokers. The goal for these brokers is to appeal to the masses and structure their rates based on volume.

While they don’t offer investment advice, new online brokers often have “robo-advisors” or online tools to provide market intelligence and portfolio analysis instead. Employees of discount brokerage firms typically work off salary rather than commissions or fees like a full-service broker. Online trading platforms are typically considered discount brokers because of their low fees and zero commission rates.

Full-service brokers offer more services like market intelligence and research, retirement planning, investment advice, and access to all investment types. Investors use this type of service when they want someone else to help with their buy and sell decisions and to help consider individual investments in the context of their overall financial situation.

Brokers earn more compensation if they trade at higher volumes and selling more investment products to their clients. For example, they may earn more compensation through a managed investment account.

Stock Brokers vs. Real Estate Brokers 🏡

Brokerage takes on a different meaning in the real estate world. These brokers work with clients who want to sell and buy real estate properties. They also must have a license to practice.

Real estate brokers typically have duties like:

  •  Researching the market values of real estate properties in both commercial and residential markets
  •  Listing and marketing properties for sale on behalf of their clients
  •  Showing properties to potential buyers
  •  Providing advice to clients on provisions, offers, and other real estate fees
  •  Prepares and submits offers to clients for consideration

Real estate brokers may also work for buyers. In this case, they help buyers find the best properties using their market knowledge and insights.

  •  Find all properties within a buyer’s preferred home shopping area and sort by price range and buyer’s income limits
  •  If a buyer wants to make an initial offer or decides on a purchase, the broker drafts up the offer and purchase agreements
  •  Brokers also negotiate with sellers to get a better price and reduced closing costs for their buyers
  •  Manage inspections and negotiating cost based on repairs needed before a purchase is final
  •  Work with buyers and sellers through closing and taking possession of a property

Broker Laws and Financial Regulation ⚖️

To become a broker, you must first register at FINRA or the Financial Industry Regulatory Authority. This is the self-regulating body for broker-dealers.

FINRA maintains that brokers adhere to a standard of conduct known as the “suitability rule.” This rule requires that the broker must have sufficient reasons for suggesting a client invest in a particular stock or product.

Another part of these standards states is known as the “know your customer” or KYC rule. This means that the broker must take steps to identify what their clients want to do with their investment portfolios.

Every broker needs to operate in compliance with rules and regulations imposed by the regulatory bodies.

In doing so, the broker can show reasonable grounds for their suggestions of an investment product. In addition, the broker must look into a client’s financial documents, such as their tax status, income, investment objectives, and other research to inform their recommendations.

These standards are separate from those required by the SEC or Securities and Exchange Commission for RIAs, AKA Registered Investment Advisers. These standards must be strictly adhered to under the Investment Advisers Act of 1940. RIAs must always abide by these rules and act in the best interests of their customers while also being completely transparent about their fees.

Real estate brokers must also abide by certain standards and rules. However, these are largely governed at a state-level. All real estate brokers must operate under a license as issued by their respective states.

There are certain laws regarding rules of conduct between clients and brokers as well. For instance, brokers have strict limitations on how they advertise incentives to prospective clients. Laws that pertain to forex brokers are much more stringent, more information can be found on our forex risk page.

How To Become a Stock Broker 📈

  1. Education. Brokers must have a high school diploma and a bachelor’s degree 👨‍🎓. Earning a degree in business, accounting, marketing, economics, or finance puts you ahead for the top positions at brokerage firms.
  2. Pass the licensing exam – This includes completing the General Securities Registered Representative Exam (Series 7). Some states also have their own Uniform Securities Agents State Law Exam (Series 63).
  3. Get a certificate – Increase employment opportunities by getting a certification as a Certified Financial Planner (CFP) or a Chartered Financial Analyst (CFA).
  4. Pick the right firm ✅ – Some companies pay for their employees’ MBA degrees while others expect you to work 60 hours for an extremely small salary and no commission. If you want to earn higher salaries, you may want to intern first and understand what type of brokerage is best for you.

Should you go for an MBA? Most brokers who want to advance do end up in a Master of Business Administration program, and they combine it with a CFA program.

Now that you know the basics of how stock brokers operate, you can get started with one and boost your stock trading strategies.
