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.

Automated trading – A platform that offers automation capabilities enables a trader to make market moves even if he/she is not at the computer at the time. The classic “stop loss” feature is a simple form of automation, but there are much more advanced platforms that enable you to program your own trading robot to carry out elaborate strategies or to react much faster than you can do yourself.
Understand the risks associated with the stocks you are investing in. In the company’s 10-K, there is an extensive section that talks about the company’s risks. You also need to understand your own tolerance for risk. If you invest in a stock that is highly volatile and you are not comfortable with market fluctuation, owning the investment will make you anxious and more likely to sell when it does not make sense strategically.

ECN/Level 2 quotes: ECNs, or electronic communication networks, are computer-based systems that display the best available bid and ask quotes from multiple market participants and then automatically match and execute orders. Level 2 is a subscription-based service that provides real-time access to the Nasdaq order book composed of price quotes from market makers registering every Nasdaq-listed and OTC Bulletin Board security. Together, they can give you a sense of orders being executed in real time.
Before deciding where to allocate your investments, it’s critical to think about your long-term and short-term goals. It’s important to know how much risk you are willing to accept. As you approach retirement, fixed-income securities, such as highly-rated bonds and money market accounts, offer a greater level of safety. But a younger investor might want a more high-risk, high-reward strategy for at least part of their investments to maximize returns over a long period of time.
