By the same token, volume characteristics of a breakout also can have a shortened time frame. Rather than the 50-day moving average of volume as your threshold for heavy turnover, look to the volume of the shorter consolidation area for clues. If the breakout volume can surpass the recent activity, that can be a sufficient confirmation of strength.
News provides the majority of opportunities from which day traders capitalize, so it is imperative to be the first to know when something significant happens. The typical trading room contains access to the Dow Jones Newswire, constant coverage of CNBC and other news organizations, and software that constantly analyzes news sources for important stories.  
Another trading method is known as fading the gap at the open. When the opening price shows a gap from the previous day’s close, taking a position in the opposite direction of the gap is known as fading the gap. For days when there is no news or there are no gaps, early in the morning, day traders will take a view on the general direction of the market. If they expect the market to move up, they would buy securities that exhibit strength when their prices dip.

The systems by which stocks are traded have also evolved, the second half of the twentieth century having seen the advent of electronic communication networks (ECNs). These are essentially large proprietary computer networks on which brokers can list a certain amount of securities to sell at a certain price (the asking price or "ask") or offer to buy a certain amount of securities at a certain price (the "bid").
You're probably looking for deals and low prices, but stay away from penny stocks. These stocks are often illiquid, and chances of hitting a jackpot are often bleak. Many stocks trading under $5 a share become de-listed from major stock exchanges and are only tradable over-the-counter (OTC). Unless you see a real opportunity and have done your research, stay clear of these.
