Scalping in forex trading is a trading style where traders aim to make small profits on each trade. It involves opening a large number of trades within a short period of time, usually a few minutes or even seconds. Scalping is a risky trading style as traders are exposed to high levels of risk. Profits and losses can occur very quickly, making it difficult to manage trades. As such, it is important to have a high level of discipline and risk management when scalping in forex trading.
