Intraday trading and scalping are both short-term trading strategies, but they have some key differences. Intraday trading involves buying and selling financial instruments within the same trading day, with the goal of profiting from short-term price movements. Scalping, on the other hand, is an even shorter-term strategy that involves taking advantage of small price movements in a financial instrument. Scalpers will typically hold positions for only a few seconds to a few minutes, and they often use high leverage to make large profits from small price movements.
