Online discount brokers: This label is generally given to the companies you see on the list here. While discount brokers are increasingly offering "extras" like research on stocks and funds, they primarily exist to help you place orders to buy investments at a very low cost. Many investors don't need the hand-holding of a full-service broker, and would prefer to save money by paying no commission for online stock trades. That way they ensure more of their money goes toward their investment portfolio, not paying for frills.
The biggest obstacle to stock market profits is an inability to control one’s emotions and make logical decisions. In the short-term, the prices of companies reflect the combined emotions of the entire investment community. When a majority of investors are worried about a company, its stock price is likely to decline; when a majority feel positive about the company’s future, its stock price tends to rise.
How user-friendly is their platform? – The trading platform provided by the broker needs to work for you. Most brokers offer several to choose from, some will tick the boxes for the average day trader, others will offer more advanced platforms for the veteran trader. Likewise, does it suit your hardware – is the platform compatible on Mac, PC, Linux, or whatever you use?

Note that once a broker has identified you as a pattern day trader due to the above activity, your account will likely be considered a pattern day trading account going forward, even if you don’t continue to meet the definition. If you decide to stop day trading, you’ll want to contact your brokerage and ask that they remove the minimum equity requirement from your account.

All of these factors must be considered before choosing an online broker. Do you want to trade or invest? Do you want a great mobile app to check your portfolio wherever you are? What types of assets are you looking to invest in? Answering these questions is not always easy. You can check out our guide to choosing a stock broker to gain further insight so you can make a sound decision. Once you've made a decision on a broker, you can also check out our guide to opening a brokerage account.
The least demanding way to invest in the stock market is to invest through a fund. There are two types of funds. First is the actively managed mutual funds which have higher fees—92% of these funds fail to beat the underlying index over any three-year period. The second type is the index tracking fund, which typically has lower costs and is more effective in matching the growth of the stock market. This means they are growing in popularity because of the higher return on investment you receive. You should also use the most tax efficient way to invest: using your Investment Retirement Account (IRA) first. It’s best to invest in a low-cost, index-tracking fund through your tax-free IRA.

Every online brokerage firm on the list above has its strengths and weaknesses. It might be ideal for one customer and at the same time might not work for someone else. Before opening an account, there are a lot of parameters to consider besides commissions, well-known brokerage name, and pretty website. Some of the most important of these parameters are surcharges and fees; friendliness to client's knowledge level (perhaps one is a beginner? or needs a professional-level trading platform?); availability of investment products a client wants to buy (for example forex, futures, or NTF mutual funds) as well as availability of online community, virtual trading, and discounts. We suggest to investors to take a time to read brokerage reviews, and see for themselves if a particular firm is the right fit.
If you’re interested in day trading, our recommendation is to allocate a small portion of your overall portfolio to the strategy – no more than 5% or 10%, tops. That way, if you lose money — as you are likely to do, at least at first — those losses are at least capped. The rest of your portfolio should be invested in long-term, diversified investments like low-cost index funds.
