MACD (Moving Average Convergence and Divergence) was put forward by Geral Appel in 1979. It is a short-term (usually 12 days). Moving average line And the long term (commonly used as 26 days) moving average line between the polymerization and separation, to buy and sell time to determine the technical indicators.

MACD is called exponential smoothing, which is derived from the double moving average. The moving average line subtracts the slow moving average. The meaning of MACD is basically the same as that of the double moving average, but it is more convenient to read. When MACD turns from negative to positive, it is a signal to buy. When MACD turns from positive to negative, it is a signal to sell. When MACD changes at a large angle, the gap between the fast moving average line and the slow moving average line is very fast.
