The scalping strategy is very common in currency trading, since Forex is a market that generally presents very clear trends in very short periods of time. There are different indicators for scalping, such as the RSI (relative strength) or the investment volume, the important thing is to choose one and apply it correctly. An example of a one-minute scalping strategy is buying 20,000 euros in EUR / USD when the currency pair is trending upwards (such as + 0.33%). Since it is relatively rare for the trend to reverse in one minute, the trader following this Forex scalping trend would sell them after one minute. Typically at the end of the sale of the currency is that the investor will earn a margin close to + 0.33% for the total value of the investment.
