MACD is a technical analysis tool, which can help us to judge market trends and trading signals. Among them, DIF in MACD is the difference of moving average, which is used to reflect the short-term trend of stock price. The higher the DIF value, the higher the stock price relative to the past average, and the lower the stock price.

the calculation of dif needs to use two moving averages, one is the 12-day moving average and the other is the 26-day moving average. DIF=12-day moving average -26-day moving average. The changing trend of DIF value is also very important. If DIF shows an upward trend, it means that the stock price may continue to rise. On the contrary, it may fall.

DIF value can be used together with other indicators of MACD to form a complete trading strategy. When DIF crosses the 9-day moving average from bottom to top (that is, the MACD bar line forms a golden cross signal above the -axis), it can be considered as a buy signal; On the contrary, it is a sell signal. Through fast and effective index calculation, MACD and DIF have become necessary tools for stock market analysts to predict market fluctuations and stock price fluctuations.
