Scalping is one of the quickest strategies employed by active traders. Essentially, it entails identifying and exploiting bid-ask spreads that are a little wider or narrower than normal due to temporary imbalances in supply and demand.
A scalper does not attempt to exploit large moves or transact high volumes. Rather, they seek to capitalize on small moves that occur frequently, with measured transaction volumes. Since the level of profit per trade is small, scalpers look for relatively liquid markets to increase the frequency of their trades. Unlike swing traders, scalpers prefer quiet markets that aren’t prone to sudden price movements.
