Scalping

What Is Scalping?

Scalping is a trading strategy built on a simple idea: capture small price movements many times during a single session. Instead of holding a position for days or weeks, a scalper opens and closes trades within seconds or minutes, aiming to keep only a few cents or a fraction of a percent on each one. The profits from many small wins are meant to add up to something meaningful.

Scalpers usually trade highly liquid instruments, such as large stocks, index futures, or major currency pairs, because these markets have tight bid-ask spread and enough volume to enter and exit quickly at predictable prices.

How Scalping Works

A scalper typically looks for brief imbalances in order flow, short-lived changes in volume, or small gaps between prices on related markets. Many use limit order entries to control the price they pay, and tight stop-loss order levels to limit losses when a trade moves against them.

Because each trade is small, costs matter a great deal. Commissions and the spread between buy and sell prices can erase the profit from a trade, so scalpers often trade in large sizes or through brokers with low fees.

Advantages and Disadvantages

Scalping can limit exposure to overnight news and sudden moves, and it can produce many trades quickly. However, it demands intense focus, fast execution, and reliable technology. Transaction costs, slippage, and the psychological strain of constant decisions can make it difficult to stay profitable. Many short-term traders lose money over time, and regulators in several countries have warned investors about the risks of frequent, leveraged short-term trading.

Scalping is a demanding style that depends heavily on costs, speed, and discipline, and it is not a suitable approach for most individual investors.
