This combination of factors has made day trading in stocks and stock derivatives (such as ETFs) possible. The low commission rates allow an individual or small firm to make a large number of trades during a single day. The liquidity and small spreads provided by ECNs allow an individual to make near-instantaneous trades and to get favorable pricing.
Scalping is a trading strategy geared towards profiting from minor price changes in a stock's price. Traders who implement this strategy place anywhere from 10 to a few hundred trades in a single day with the belief that small moves in stock price are easier to catch than large ones; traders who implement this strategy are known as scalpers. Many small profits can easily compound into large gains, if a strict exit strategy is used to prevent large losses.
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.
