Below is the list of online brokers doing business in the United States. Their names are ordered alphabetically. The table contains brokerage name, firms' website links, commissions on stock and ETF trades, and minimum amounts required to open a new brokerage account. There you could also find the discount stock trading companies ratings as well as links to detailed account reviews.
You're probably looking for deals and low prices, but stay away from penny stocks. These stocks are often illiquid, and chances of hitting a jackpot are often bleak. Many stocks trading under $5 a share become de-listed from major stock exchanges and are only tradable over-the-counter (OTC). Unless you see a real opportunity and have done your research, stay clear of these.
With the large library of educational and research content, you can enter the high-speed options trading world with your eyes wide open to the risks and opportunities. That said, the competitive costs and quality trading platforms make it a worthy consideration for even the most experienced traders. Accounts require a $1,000 minimum to access options trading.
What would make me sell: Sometimes there are good reasons to split up. For this part of your journal, compose an investing prenup that spells out what would drive you to sell the stock. We’re not talking about stock price movement, especially not short term, but fundamental changes to the business that affect its ability to grow over the long term. Some examples: The company loses a major customer, the CEO’s successor starts taking the business in a different direction, a major viable competitor emerges, or your investing thesis doesn’t pan out after a reasonable period of time.

It depends. 24/7 support is essential to some investors, while others may be completely fine using online chat during regular market hours or receiving an email back within one business day. That said, most investors neglect to think about a market crisis like a flash crash. In our experience, it certainly doesn't hurt to have reliable customer service available for whenever the need may arise.


TD Ameritrade, one of the largest online brokers, has made significant efforts to market itself to beginner investors through social media. Work is still being done to further streamline its web and mobile experiences and make them more accessible to new users, but the resources new investors can already access are exceptional. Education is a key component of TD Ameritrade’s offerings. You’ll find expanded learning pathways, ranging from beginner to advanced, to help clients understand everything from basic investing concepts to extremely advanced derivatives strategies. You can open an account and poke around without making a deposit, and take advantage of all the learning opportunities until you’re comfortable. TD Ameritrade wants new investors to become more confident, and to trade additional asset classes as their skills grow.
Fidelity earned our top spot for the second year running by offering clients a well-rounded package of investing tools and excellent order executions. It has continued to quietly enhance key pieces of its mobile-responsive website while committing itself to lowering the cost of investing for its clients. Fidelity joined in the rush to cut equity and base options commissions to zero in October 2019 but remains devoted to offering top-quality research and education offerings to its clients. The firm also makes it easy for clients to earn interest by sweeping uninvested cash into a money market fund. Fidelity also shares the revenue it generates from its stock loan program, and allows clients to choose which stocks in their portfolios can be loaned out.
To trade stocks online successfully, some stock traders rely purely on their trading tools. Trading platforms come in one of three forms: desktop, web (browser), or mobile. Advanced charting, scanning, hotkeys, virtual trading, watch lists, ladder trading, Level II quotes, and backtesting are just a sampling of the features some brokers offer. To compare trading platform features, use the online brokerage comparison tool.
One of the most common mistakes in stock market investing is trying to time the market. Time the market, or “market timing,” means trying to figure out the best time to get in the market, or invest. It also means the best time to get out of the market, or sell. It’s not easy to be right on both ends. It can be unsettling to experience market volatility, so that’s why it’s important to understand the difference between savings (which are more stable) and investments (which can be more volatile). It’s the time in the market that is more important, not necessarily timing the market.

Risk Disclosure: Trading in financial instruments and/or cryptocurrencies involves high risks including the risk of losing some, or all, of your investment amount, and may not be suitable for all investors. Prices of cryptocurrencies are extremely volatile and may be affected by external factors such as financial, regulatory or political events. Trading on margin increases the financial risks.
A full-service broker might charge you as much as $300 in fees to invest $10,000 in a mutual fund or up to $100 to invest that same amount in a stock. On the other hand, a discount broker typically charges no commissions for online trades and has a list of no-commission mutual funds. That means the cost difference alone is reason enough for new investors to use a discount brokerage firm.

The commission structure for options trades tends to be more complicated than its equivalent for stock trades. Until the commission cuts that swept the industry in the fall of 2019, most brokers charged a fee for each leg of an options spread, plus a commission per contract being traded. The per-leg fees, which made 2- and 4-legged spreads expensive, have been eliminated for the most part. We are seeing some brokers place caps on commissions charged for certain trading scenarios. 
While that may sound like outdated advice, in late 2012, an American marketing executive explained how he had turned $20,000 into $2 million during the recession. Chris Camillo explained that Wall Street is quite homogenous and tends to be behind the curve on trends involving females, young people and those on low incomes. Camillo invested in stocks that anyone could have, he just spotted trends before the investment bankers did and was able to make some very sizable profits.
The best way to practice: With a stock market simulator or paper-trading account. Many brokers offer these virtual trading platforms, and they essentially allow you to play the stock market with Monopoly money. Not only do you get to familiarize yourself with trading platforms and how they work, but you also get to test various trading strategies without losing real money. The link above has a list of brokers that offer these play platforms.
