Scalping

Definition:
Scalping is a short-term trading strategy that aims to profit from small price movements in a security. Traders known as scalpers enter and exit positions within seconds or minutes, executing many trades in a day to capitalize on tiny price fluctuations, often in high-liquidity markets.

Key Characteristics:

Ultra-Short Timeframes: Seconds to minutes
High Trade Volume: Dozens or even hundreds of trades per day
Small Profit Margins: Relies on fractions of a cent or percentage per trade
Minimal Holding Risk: Positions rarely held overnight
Requires Speed and Precision

Example:

A scalper notices a stock priced at $100.00 has a tight bid-ask spread. They buy at $100.00 and sell moments later at $100.05, making a $0.05 profit per share. Repeating this strategy 200 times a day with 1,000 shares per trade could yield substantial profits if fees and slippage are managed.
