MACD Line: It is the 12-day exponential moving average (EMA) minus the 26-day exponential moving average. Compared with the simple moving average, the exponential moving average places more emphasis on recent prices and could better reflect price fluctuations in the short term. By utilizing 12-day EMA minus 26-day EMA, the MACD line could capture the short-term capital flow in a more precise way. If the MACD line is greater than zero, the trend of buying in the short term is relatively stronger.
