If the short-term 12 is enlarged, the sensitivity of MACD to short-term fluctuation will be reduced, and the situation of dead fork of golden fork will be slowed down, so it is more effective for investors to operate with fluctuation, which can filter out short-term fluctuation and buy and sell at a more certain time. If the value of 12 decreases, the MACD will become sensitive, and the golden fork and the dead fork will appear in a shorter time, which is beneficial to short-term investors.
In addition, the same is true for the parameter adjustment in the following 26. The specific setting method is to right-click this indicator-after modifying the indicator parameters, you will see three default parameters, and then you can replace this value, and some of them are set to 5, 34 and 5; Some settings are 15, 55, 7, depending on your own needs and actual use.
MACD, called Similarities and Differences Moving Average, 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. The change of MACD represents the change of market trend, and MACD of different K-line levels represents the trading trend in the current level cycle.
