MACD is called exponential smoothing, which is developed from the double exponential moving average. The fast exponential moving average (EMA12) is subtracted from the slow exponential moving average (EMA26) to obtain the fast DIF, and then the MACD column is obtained by using 2¡Á(the 9-day weighted moving average DEA of the fast DIF-DIF).
The meaning of MACD is basically the same as that of the double moving average, that is, the discrete and aggregation of the fast and slow moving averages represent the current long and short state and the possible development and change trend of stock prices, but it is more convenient to read.
When the MACD moves from negative to positive, it is a sign to buy.
When the MACD moves from positive to negative, it is a sign to sell.
When the MACD changes at a large Angle, the gap between the fast moving average and the slow moving average opens up very rapidly, representing a shift in the market’s general trend.
