Day trading is the act of buying and selling a financial instrument within the same day or even multiple times over the course of a day. Taking advantage of small price moves can be a lucrative game—if it is played correctly. But it can be a dangerous game for newbies or anyone who doesn't adhere to a well-thought-out strategy. What's more, not all brokers are suited for the high volume of trades made by day traders. Some brokers, however, are designed with the day trader in mind. You can check out our list of the best brokers for day trading to see which brokers best accommodate those who would like to day trade.
Fees are another important consideration while choosing trading platforms. For example, traders who employ scalping as a trading strategy will gravitate towards platforms with low fees. In general, lower fees are always preferable but there may be trade-offs to consider. For example, low fees may not be advantageous if they translate to fewer features and informational research.
Define and write down the conditions under which you'll enter a position. "Buy during uptrend" isn't specific enough. Something like this is much more specific and also testable: "Buy when price breaks above the upper trendline of a triangle pattern, where the triangle was preceded by an uptrend (at least one higher swing high and higher swing low before the triangle formed) on the two-minute chart in the first two hours of the trading day."
When you buy a stock, you should have a good reason for doing so and an expectation of what the price will do if the reason is valid. At the same time, you should establish the point at which you will liquidate your holdings, especially if your reason is proven invalid or if the stock doesn’t react as expected when your expectation has been met. In other words, have an exit strategy before you buy the security and execute that strategy unemotionally.
To make comparisons between companies, sectors and markets a little easier, there are a number of mathematical models used. The most common and often the most helpful is the P/E ratio. The Price to Earnings ratio takes the share price and is divided by the earnings per share. It is possible to calculate this using past earnings, projected future earnings and with all sorts of moving averages ;-) Therefore, this is one number that it is vital for any investor to know and understand.
By making it to this article you've taken an important first step in your investing journey -- picking a stock broker. There are many brokers to choose from, and each offers something a little bit different. See our guide below for more information on what you should be looking for, along with a list of our picks for best online stock brokers for beginners.
When selecting a new online broker, the first step is to read reviews and see what features matter most to you. Are low-cost trade commissions most important?

A broker – Your broker will be your gatekeeper to the market. They will facilitate your trades in return for a commission on your trades. When you’re making so many trades each day, an expensive broker could seriously cut into your profits in the long term.

This education really ought to include one of the daily papers that covers the movements on the stock exchange (information here) in detail, such as the Financial Times or Wall Street Journal. Remember, the investment bankers that you are competing against have Bloomberg terminals and Reuters subscriptions, while everyone else is watching CNN and MSNBC. Since everyone is reading the same things on the same days, these might not be the best places to pick up your share market tips...
For the active trader, execution speed and fill price are very important. I won’t get too in depth here but I have tested many of these brokers and there can be noticeable differences in trade execution times and quality. For the majority of investors, saving a penny per share on a 100 shares order isn’t the end of the world, but for active traders it is something to look into. To understand Order Execution, read this guide.
Pro tip: Another way to make sure your portfolio is diversified is to invest if different types of investments. Some people like to mix things up by investing in fine art through Masterworks. Fun fact – blue chip art returned 10.6% in 2018 compared to a 5.1% loss for the S&P 500. Others choose to invest in real estate through a company like DiversyFund.

Since the underlying businesses operate in differing markets, sectors and countries, their quoted prices move independently as supply and demand in them rises and falls and new information is released to the public about the current business situation. It is the changing of prices that offer investors the opportunity to make a capital gain (or loss) via ownership.
As you near retirement, a full-service brokerage firm may make more sense because they can handle the complex "stuff" like managing your wealth in a tax-efficient way, or setting up a trust to pass wealth on to the next generation, and so on. At this point, it may be advantageous to pay 0.50%-1% of your assets in fees each year for advice and access to a certified public accountant who can help you with the nitty-gritty details that are more important as you start making withdrawals (rather than contributions) from your retirement accounts.
Control greed – Greed often influences traders in the following way; you enter a trade at $80 with a target of $95, but then it hits $95 and you think ‘I’ll just hold on a bit longer and increase profits further’. This only ends with you eventually losing big. The solution; stick rigidly to your strategy. Think long term and don’t deviate from your strategy, there’s simply no need to gamble.
We all know someone who has “tried” investing in the stock market, lost a lot of money, and denounced it as a scam. The truth is that the stock market is not a scam; it is an incredible wealth-building tool. Most people who lose money in stocks do so because they get spooked by a dip in the market and then panic. Fearing that they will lose all of their investment, they hastily sell their shares, often at a loss. This should not be the case. Investors must keep in mind that over the long run, the stock market tends to increase in value, so they should think twice before selling their investments in a panic.
Finally, keep in mind that if trading on margin—which means you're borrowing your investment funds from a brokerage firm (and bear in mind that margin requirements for day trading are high)—you're far more vulnerable to sharp price movements. Margin helps to amplify the trading results not just of profits, but of losses as well if a trade goes against you. Therefore, using stop losses is crucial when day trading on margin.

The most feared words on any stock exchange are margin call. A margin call is made when a position is losing money and more money is required by the broker to keep the trade open. If and when a stock ticker moves quickly, there can be people whose borrowing levels literally bankrupt them as things get worse ... fast. Volatility can be either a blessing or a curse, but if you have too much leverage, it can break a trader.
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. 
When thinking about the mindset of investors, The Great Crash 1929 by J.K.Galbraith (reviewed here) should also be required reading. Typically, any sustained fall in prices - known as a bear market - is very destructive to wealth. However, as Galbraith explains wonderfully, each bear market is unique and is a reflection of the bull market that came before it. The book explains a great deal about the feedback loops that can exist when prices rise and fall as more people are either sucked into or forced out of holdings. It is the reference work about a very important slice of Wall Street history.
If you’re an active trader looking to try your hand at beating the market, you probably have a good idea of what you want in a brokerage: low costs, premium research, innovative strategy tools and a comprehensive trading platform. Below, we’ve selected the best online brokers in a variety of categories so you can choose one based on your personal priorities.
