What is the most accurate parameter for macd adjustment?

1. Through continuous testing, the author concludes that the price H160min) K-line MACD has two sets of parameters with high practical value, namely 6, 30, 6) and 6, 30, 9).

2. MACD indicators set by two groups of parameter values have significant performance changes in sensitivity to price trends or early warning of future price trends, and the accuracy changes between them are not periodic according to time span. The difference between stock and spot is different. It will also be improved and can be used as another tool for users.

3.MACD index is the most common indicator, and many investors are not familiar with its principle, usage, advantages and disadvantages. As some textbooks say, the main disadvantage of MACD is that it is too slow to respond to price trends and cannot provide useful hints in a short time. So, what can be done to change this situation? The author thinks that this defect can be made up to some extent by changing the EMA parameters of the index. The author thinks that setting the fast EMV parameter to 15 and the slow EMA parameter to 90 is a better setting method.
