With low barriers to entry in the trading world, the number of people trying their hands at day trading and other strategies such as scalping has increased. Newcomers to scalping need to make sure the trading style suits their personality because it requires a disciplined approach. Traders need to make quick decisions, spot opportunities and constantly monitor the screen. Those who are impatient and feel gratified by picking small successful trades are perfect for scalping.
Scalpers use technical analysis but within this style, can be either discretionary or system traders. Discretionary scalpers will make each trading decision in real time (albeit very quickly), whereas system scalpers follow a scalping system without making any individual trading decisions. Scalpers primarily use the market's prices to make their trading decisions, but some scalpers also use one or more technical indicators, such as moving averages, channel bands, and other chart patterns.
Liquidity - The liquidity of a market affects the performance of scalping. Each product within the market receives different spread, due to popularity differentials. The more liquid the markets and the products are, the tighter the spreads are. Some scalpers like to trade in a more liquid market since they can move in and out of large positions easily without adverse market impact. Other scalpers like to trade in less liquid markets, which typically have significantly larger bid-ask spreads. Whereas a scalper in a highly liquid market (for example, a market maintaining a one-penny spread) may take 10,000 shares to make a 3 cent gain ($300), a scalper in an illiquid market (for example, a market with a 25 cent spread) may take 500 shares for a 60 cent gain ($300). While there is theoretically more profit potential in a liquid market, it is also a "poker game" with many more professional players which can make it more difficult to anticipate future price action.
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.
Scalping is a fast-paced activity for nimble traders. It requires precision timing and execution. Scalpers use day trading buying power of four to one margin to maximize profits with the most shares in the shortest amount of holding time. This requires focusing on the smaller time frame interval charts such as the one-minute and five-minute candlestick charts. Momentum indicators such as stochastic, moving average convergence divergence (MACD) and relative strength index (RSI) are commonly used. Price chart indicators such as moving averages, Bollinger bands and pivot points are used as reference points for price support and resistance levels.

Successful traders have to move fast, but they don't have to think fast. Why? Because they've developed a trading strategy in advance, along with the discipline to stick to that strategy. It is important to follow your formula closely rather than try to chase profits. Don't let your emotions get the best of you and abandon your strategy. There's a mantra among day traders: "Plan your trade and trade your plan."
