Scalping is a high-frequency short-term trading method that accumulates profits by repeatedly entering and exiting the market in extremely short timeframes to capture small price differences. Each trade typically lasts only a few seconds to a few minutes, relying on quick reactions and stable technical analysis, such as candlestick signals, moving average crossovers, or volume changes. This strategy is particularly suitable for highly liquid assets, such as BTC, ETH, or popular US stocks. Its advantages include low risk and high flexibility, but it also places extremely high demands on the trader's psychological quality, operational discipline, and transaction cost management. If the platform has high latency or significant slippage, it will greatly affect profits. For investors with good execution and risk management capabilities, scalping can be expected to generate stable returns in volatile markets.
