2.MACD dead fork: DIFF breaks through DEA from top to bottom, which is a selling signal.
When applying MACD, the fast moving average (generally 12 days) and the slow moving average (generally 26 days) should be calculated first. These two values are used as the basis to measure the "difference" between the two (fast and slow lines). The so-called "DIF" is the average value of 12 minus the average value of 26. Therefore, in the continuous upward trend, the average of 12 is above the average of 26. At the same time, the positive deviation (+DIF) will become larger and larger. On the contrary, in the downward trend, the deviation value may become negative (-DIF) and become larger and larger. As for the market turning point, the positive and negative deviation should be reduced to a certain extent, which is the real signal of market reversal. The inversion signal of MACD is defined as the 9-day moving average (9-day moving average) of "deviation value". ?
Extended data:
MACD is called exponential smma, which is developed from double exponential moving average. Subtract the fast exponential moving average (EMA 12) from the slow exponential moving average (EMA26) to get the express DIF, and then use 2× (the 9-day weighted moving average DEA of the express DIF-DIF) to get the MACD column. The meaning of MACD is basically the same as that of double moving averages, that is, the dispersion and aggregation of fast and slow moving averages represent the current long and short state and possible development trend of stock prices, but it is easier to read. When MACD turns from negative to positive, it is a buy signal. When MACD turns from positive to negative, it is a signal to sell. When the MACD changes at a large angle, it means that the gap between the fast moving average and the slow moving average expands very quickly, which represents the change of the market trend.
