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.
A stop-loss order is designed to limit losses on a position in a security. For long positions, a stop loss can be placed below a recent low, or for short positions, above a recent high. It can also be based on volatility. For example, if a stock price is moving about $0.05 a minute, then you may place a stop loss $0.15 away from your entry to give the price some space to fluctuate before it moves in your anticipated direction.
Finally, trading platforms may have specific requirements to qualify for their use. For example, day trading platforms may require that traders have at least $25,000 in equity in their accounts and be approved for margin trading, while options platforms may require approval to trade various types of options before being able to use the trading platform.
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.
The qualification for this award is simple: the lowest out-of-pocket costs. Tastyworks fits that bill well, as customers pay no commission to trade U.S. equities online, and there is no per-leg fee for options trades. Tastyworks has a unique fee structure for options trades, charging $1 per contract to open a position, while closing trades are free. In addition, there is a maximum of $10 per leg for options trades, so traders who place large spread orders are happy.
Trading successfully is a lot easier when investors have great tools at their disposal. A top stock broker should offer access to a wide variety of trade tools to help make the most of each and every trade. From real-time streaming quotes to last sale tickers, quality stock scanners, mobile trading apps, and level II quotes to name a few. Strong tools are essential for active investors.
Over the long run, value stocks outperform growth, so look for stocks trading at relatively cheap valuations based on price-to-earnings ratio (P/E), price-to-sales ratio (P/S), and price-to-free-cash-flow ratio (P/FCF). It is vital not to chase opportunities, but rather wait for them because patience always pays. Solid fundamentals and a large moat (barrier to entry) are also vital for long-term sustained success. Also, use technical analysis and charting to better help pinpoint both the entry and exit points for the stock under consideration—both for a target profit area and a stop loss.
A trading platform is software used for trading: opening, closing, and managing market positions through a financial intermediary such as an online broker. Online trading platforms are frequently offered by brokers either for free or at a discount rate in exchange for maintaining a funded account and/or making a specified number of trades per month. The best trading platforms offer a mix of robust features and low fees.

A trading platform is the software that enables investors and traders to place trades and monitor accounts through financial intermediaries. Oftentimes, trading platforms will come bundled with other features, such as real-time quotes, charting tools, news feeds, and even premium research. Platforms may also be specifically tailored to specific markets, such as stocks, currencies, options, or futures markets.

Many online brokerages do not limit their customers to just online stock trading. Full-service brokerages offer banking services including checking accounts, savings accounts, credit cards, mortgages, and more with deposits of up to $250,000 backed by the FDIC. Bank of America (Merrill Edge) and Chase (Chase You Invest Trade) are two examples of banks that also offer online trading.
If the strategy is within your risk limit, then testing begins. Manually go through historical charts to find your entries, noting whether your stop loss or target would have been hit. Paper trade in this way for at least 50 to 100 trades, noting whether the strategy was profitable and if it meets your expectations. If it does, proceed to trading the strategy in a demo account in real time. If it's profitable over the course of two months or more in a simulated environment, proceed with day trading the strategy with real capital. If the strategy isn't profitable, start over.

TD Ameritrade focused its 2019 development efforts on its most active clients, who are mobile-first – and in many cases, mobile-only. TD Ameritrade’s thinkorswim mobile platform has extensive features for active traders and investors alike. The workflow for options, stocks, and futures is intuitive and powerful. You’ll find lots of bells and whistles that make the mobile app a complete solution for most trading purposes, including streaming real-time data and the ability to trade from charts. The regular mobile platform is almost identical in features to the website, so it’s an easy transition. TD Ameritrade clients can trade all asset classes offered by the firm on the mobile apps.
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.
7. Don’t concentrate on the money – This may sound counterintuitive, but it makes good sense. Having money at the forefront of your mind could make you do reckless things, like taking tiny profits in fear of losing what you’ve already won, or jumping straight in so you don’t miss a move. Instead, focus on sticking to your strategy and let your strategy focus on making you money.

The trading products you can purchase using these platforms can include stocks, commodities, derivatives, bonds etc. which can be traded between the traders on the stock market with intermediates such as investment banks, stock exchanges, brokers and market makers. A communication network is set-up between the various intermediates and the traders, which facilitates proper execution of the whole system.
