Risk management - Rather than looking for one big trade, the way a trend trader might, the scalper looks for hundreds of small profits throughout the day. In this process the scalper might also take hundreds of small losses during the same time period. For this reason a scalper must have very strict risk management never allowing a loss to accumulate.
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.
Day trading is not for everyone and involves significant risks. Moreover, it requires an in-depth understanding of how the markets work and various strategies for profiting in the short term. While we remember the success stories of those who struck it rich as a day trader, remember that most do not—many will fizzle out and many will just barely stay afloat. Furthermore, don't underestimate the role that luck and good timing play—while skill is certainly an element, a rout of bad luck can sink even the most experienced day trader.

The first type of scalping is referred to as "market making," whereby a scalper tries to capitalize on the spread by simultaneously posting a bid and an offer for a specific stock. Obviously, this strategy can succeed only on mostly immobile stocks that trade big volumes without any real price changes. This kind of scalping is immensely hard to do successfully, as a trader must compete with market makers for the shares on both bids and offers. Also, the profit is so small that any stock movement against the trader's position warrants a loss exceeding his or her original profit target.
The reason is because all too often the price can drop and you will end up giving up that profit. Instead, as soon as I’ve reached my first profit target (if I’m risking $100, then as soon as I’m up $100), I’ll sell 1/2 my position and set my stop at breakeven. This method of scaling out ensures small profits on all trades that move in your favor, giving you a better percentage of success.
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.
