Scalping is one of the fastest and most dynamic trading strategies in the market. If you enjoy being constantly on the move, making quick decisions, and catching small but frequent profits, this strategy might be for you.
What is scalping?
Scalping is trading on short timeframes (from a few seconds to a couple of minutes), where the goal is to profit from the slightest price changes. For example, buy cryptocurrency for $10,200, sell for $10,205. The profit seems tiny, but throughout the day, there can be dozens or even hundreds of such trades, which collectively yield significant income.
