Some trading platforms may be agnostic to a specific intermediary or broker, while other trading platforms are only available when working with a particular intermediary or broker. As a result, investors should also consider the reputation of the intermediary or broker before committing to a specific trading platform to execute trades and manage their accounts.

Fees beyond trade commissions include inactivity fees (common with active trading brokers such as Interactive Brokers, Lightspeed, and TradeStation) and IRA fees for having a retirement account. While most brokers do not charge predatory fees, it’s still important to do your due diligence. Just like a bank account, stock brokers also make a portion of their profits off miscellaneous fees.
Buy in thirds: Like dollar-cost averaging, “buying in thirds” helps you avoid the morale-crushing experience of bumpy results right out of the gate. Divide the amount you want to invest by three and then, as the name implies, pick three separate points to buy shares. These can be at regular intervals (e.g., monthly or quarterly) or based on performance or company events. For example, you might buy shares before a product is released and put the next third of your money into play if it’s a hit — or divert the remaining money elsewhere if it’s not.

While some people do buy winning tickets or a common stock that quadruples or more in a year, it is extremely unlikely, since relying upon luck is an investment strategy that only the foolish or most desperate would choose to follow. In our quest for success, we often overlook the most powerful tools available to us: time and the magic of compounding interest. Investing regularly, avoiding unnecessary financial risk, and letting your money work for you over a period of years and decades is a certain way to amass significant assets.
Stock brokers are people or firms licensed to buy and sell stocks and other securities via the stock market exchanges. Back in the day, the only way for individuals to invest directly in stocks was to hire stock brokers to place trades on their behalf. But what was once a clunky, costly transaction conducted via landline telephones now takes place online in seconds, for a fraction of what full-service brokers used to charge for the service. Today, most investors place their trades through an online brokerage account. (A little lost? Check out our explainers on brokerage accounts and buying stocks.)
It is also important to know what you want to accomplish with your investments before you actually invest. For example, you might want to purchase a home, fund a child’s college education, or build an adequate retirement nest egg. If you set financial goals at the outset—and match your investments to achieve those goals—you are more likely to reach them.

Normally a broker will offer their customers a branded trading platform that’s more or less unique to that individual broker, but there are also independent platforms that can connect to multiple brokers. An independent platform can be a good choice for the experienced trader, while using a broker’s own platform is the easiest way to get started for beginners.
The idea of perception is important, especially in investing. As you gain more knowledge about investments – for example, how stocks are bought and sold, how much volatility (price change) is usually present, and the difficulty or ease of liquidating an investment – you are likely to consider stock investments to have less risk than you thought before making your first purchase. As a consequence, your anxiety when investing is less intense, even though your risk tolerance remains unchanged because your perception of the risk has evolved.

Imagine owning stocks in five different companies, each of which you expect to continually grow profits. Unfortunately, circumstances change. At the end of the year, you might have two companies (A & B) that have performed well so their stocks are up 25% each. The stock of two other companies (C & D) in a different industry are up 10% each, while the fifth company’s (E) assets were liquidated to pay off a massive lawsuit.

A demo account is a great way for beginners to practice trading and test a broker or trading platform without using real money. A demo account is funded with simulated money, so you can try out the broker’s platform features and get familiar with acting on the markets. A warning though – even the best practice platform can’t replicate the pressures that comes with having real money on the line, but it’s a great way to learn the basics and get started with zero risk.

There are two types of trading platforms: prop platforms and commercial platforms. As their name indicates, commercial platforms are targeted at day traders and retail investors. They are characterized by ease-of-use and an assortment of helpful features, such as news feeds and charts, for investor education and research. Prop platforms, on the other hand, are customized platforms developed by large brokerages to suit their specific requirements and trading style.
