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.

Identify a stock or ETF where the weekly trend is up and the bottoms on the daily bar chart tend to be short and sharp. Analyze how the stock or ETF has behaved since the beginning of the trend. If it has returned to the moving average 3 times and penetrated it by an average of 1.5% of its price, place a buy order approximately 1% of the instrument's price below the moving average, a little more shallow than the previous declines.
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.
Swing, or range, trading Traders find a stock that tends to bounce around between a low and a high price, called a "range bound" stock, and they buy when it nears the low and sell when it nears the high. They may also sell short when the stock reaches the high point, trying to profit as the stock falls to the low and then close out the short position.
Ultimately, each swing trader devises a plan and strategy that gives them an edge over many trades. This involves looking for trade setups that tend to lead to predictable movements in the asset's price. This isn't easy, and no strategy or setup works every time. With a favorable risk/reward, winning every time isn't required. The more favorable the risk/reward of a trading strategy, the fewer times it needs to win in order to produce an overall profit over many trades.

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.

Because scalpers focus on short-term positions with low-profit margins, the best scalping strategies (such as the Triple S strategy mentioned below) require some leverage. It's recommended that scalpers start with a large amount of capital. Opening and closing larger positions allow you to reduce the marginal costs of trading and maximize potential gains.
Sincere interviewed professional day trader John Kurisko, Sincere states, Kurisko believes that some of the reversals can be blamed on traders using high-speed computers with black-box algorithms scalping for pennies. “That’s one of the reasons many traders get frustrated with the market. The timing is not like it used to be, and many of the old rules don’t work like before.” [2]
Rebate trading is an equity trading style that uses ECN rebates as a primary source of profit and revenue. Most ECNs charge commissions to customers who want to have their orders filled immediately at the best prices available, but the ECNs pay commissions to buyers or sellers who "add liquidity" by placing limit orders that create "market-making" in a security. Rebate traders seek to make money from these rebates and will usually maximize their returns by trading low priced, high volume stocks. This enables them to trade more shares and contribute more liquidity with a set amount of capital, while limiting the risk that they will not be able to exit a position in the stock.[16]
Define and write down the conditions under which you'll enter a position. "Buy during uptrend" isn't specific enough. Something like this is much more specific and also testable: "Buy when price breaks above the upper trendline of a triangle pattern, where the triangle was preceded by an uptrend (at least one higher swing high and higher swing low before the triangle formed) on the two-minute chart in the first two hours of the trading day."
