But this description of swing trading is a simplification. In reality, swing trading sits in the middle of the continuum between day trading to trend trading. A day trader will hold a stock anywhere from a few seconds to a few hours but never more than a day; a trend trader examines the long-term fundamental trends of a stock or index and may hold the stock for a few weeks or months. Swing traders hold a particular stock for a period of time, generally a few days to two or three weeks, which is between those extremes, and they will trade the stock on the basis of its intra-week or intra-month oscillations between optimism and pessimism.
It needs sheer dedication, hard work, patience, quick wit and immense knowledge to be successful in intraday trading. Successful intraday trading involves 90% waiting and 10% execution. So, yes, it can make a trader rich in a relatively short period of time if the correct processes are followed, and yes, it is possible to hold on to the profits in the long-term if the correct strategies are followed.
Scalping can appear easy because a scalper might make an entire day's profit within a few minutes. However, in reality, ​scalping can be quite challenging because there is very little room for error. If you do decide to try scalping, make sure that you do so by using a trading simulator, until you are consistently profitable and no longer make any beginning mistakes, such as not exiting your trades when they move against you.
FX 1-minute scalping is a day trading strategy, as it involves opening a certain position, gaining a few pips, and then closing the position afterward. It is one of the most basic and resourceful trading strategies. The main aspect of Forex scalping is quantity. It is not unusual for traders to place more than 100 trades a day. For this reason, it is important to pick a broker with the smallest spreads, as well as the smallest commissions.
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.  
This strategy is mostly only done by day traders. It requires that you have access to one to several real-time news sources and can make split second decisions. News and rumors can provide large amounts of volatility and high emotion creating great opportunities if traded properly. The biggest challenge of trading this strategy is anticipating the market’s reaction to the news and how it effects the price of the stock. Click here for more information on trading news and rumors.
Years ago, when stocks were quoted in fractions, there was a standard spread of 1/16 of a dollar or a "teenie". This spread allowed scalp traders to buy a stock at the bid and immediately sell at the ask. Hence the teenie presented clear entry and exit levels for scalp traders. The scalp trading game took a turn for the worst when the market converted to the decimal system. The decimal system closed the "teenie" often times to within 1 penny for high volume stocks. This overnight shifted the strategy for scalp traders. A scalp trader now had to rely more on their instincts, level II, and the time and sales window.
