The increment of MACD red column indicates that the kinetic energy of bulls is gradually accumulating, thus pushing up the price of gold and silver, and the K line will form a positive line, and the increment of MACD red column will benefit the market outlook.

2、 ? MACD red column contraction

The shrinkage of MACD red column shows that the kinetic energy of bulls is gradually exhausted, thus suppressing the decline of gold and silver prices, and the solid part forming the Yang K line will be cut. When the shrinkage of MACD red column reaches zero, the K line will form or deviate from the lower shadow line, and the shrinkage of MACD red column is bad for the market outlook.

3、 ? MACD green column increment

The increment of MACD green column shows that short-term kinetic energy is gradually accumulating, which suppresses the decline of gold and silver prices, and the K line will form a negative line. The increment of MACD green column is bad for the market outlook.

4、 ? MACD green column contraction

The shrinkage of MACD green column indicates that the short-term kinetic energy is gradually exhausted, so the price of gold and silver is supported at a relatively low level, and the solid part forming the negative K line will be cut. When the MACD green column is zero, the K line will form or deviate from the shadow line, and the shrinkage of the MACD green column is good for the market outlook.

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.
