Scalping strategy is a form of ultra-short-term trading that seeks to quickly profit from small price fluctuations, with positions typically held for very short durations (usually seconds to minutes). It relies on high-frequency trading, precise order placement, and strict profit-taking and stop-loss measures. Common techniques include MACD, Bollinger Bands, VWAP, and order book data, suitable for high liquidity markets such as BTC, ETH, etc. Scalping has very high requirements for trading costs and platform response speed, making it suitable for experienced, quick-reacting traders, but not for swing or trend traders. Although the risks are small, they are frequent, and the cumulative effect should not be overlooked.
