Swing trading refers to the practice of trying to profit from market swings of a minimum of one day and as long as several weeks. In contrast to swing traders, day traders usually are in and out of the market in one day and trend traders often hold positions for several months. So, in terms of length of holding a trade, swing traders are in between day traders and trend traders.
Smaller moves, easier to obtain - A change in price results from imbalance of buying and selling powers. Most of the time within a day, prices stay stable, moving within a small range. This means neither buying nor selling power control the situation. There are only a few times which price moves towards one direction, i.e. either buying or selling power controls the situation. It requires bigger imbalances for bigger price changes. It is what scalpers look for - capturing smaller moves which happen most of the time, as opposed to larger ones.

Many times, neither a bullish nor a bearish trend is present, but the security is moving in a somewhat predictable pattern between parallel resistance and support areas. When the market moves up and then pulls back, the highest point reached before it pulls back is the resistance. As the market continues up again, the lowest point reached before it climbs back is the support. There are swing trading opportunities in this case too, with the trader taking a long position near the support area and taking a short position near the resistance area.

On the other hand, a bearish crossover occurs when the price of a security falls below these EMAs. This signals a potential reversal of a trend, and it can be used to time an exit of a long position. When the nine-period EMA crosses below the 13-period EMA, it signals a short entry or an exit of a long position. However, the 13-period EMA has to below the 50-period EMA or cross below it.
The goal of swing trading is to capture a chunk of a potential price move. While some traders seek out volatile stocks with lots of movement, others may prefer more sedate stocks. In either case, swing trading is the process of identifying where an asset's price is likely to move next, entering a position, and then capturing a chunk of the profit from that move.

Day traders are attuned to events that cause short-term market moves. Trading the news is a popular technique. Scheduled announcements such as economic statistics, corporate earnings or interest rates are subject to market expectations and market psychology. Markets react when those expectations are not met or are exceeded, usually with sudden, significant moves, which can benefit day traders.

This is usually reserved for traders working for larger institutions or those who manage large amounts of money. The dealing desk provides these traders with instantaneous order executions, which are particularly important when sharp price movements occur. For example, when an acquisition is announced, day traders looking at merger arbitrage can place their orders before the rest of the market is able to take advantage of the price differential.

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.
