According to the di value, the DX index value can be calculated. The calculation method is to divide the absolute value of the difference between +DI and -di by the percentage of the sum to get the trend index DX. Because the fluctuation range of DX is relatively large, the average trend index ADX is generally calculated smoothly in a certain period of time. The specific process is as follows:

DX=(DIDIF÷DISUM)× 100

Where DIDIF is the absolute value of the price difference between the rising index and the falling index.

DISUM is the sum of rising and falling indicators.

ADX is the moving average of a period n of DX.

Evaluation value ADXR

ADXR index can also be added to DMI index, which is more conducive to the judgment of the market.

ADXR is calculated as follows:

ADXR= (ADX of the current day+ADX of the previous day) ÷ 2

Like other indicators, DMI indicators include daily DMI indicators, weekly DMI indicators, monthly DMI indicators, annual DMI indicators and minute DMI indicators. Daily DMI index and weekly DMI index are often used to judge the stock market. Although their calculated values are different, the basic calculation method is the same. In addition, with the development of stock market software analysis technology, investors only need to master the basic principle and calculation method of DMI formation, and do not need to calculate the value of indicators. More importantly, they need to use DMI indicators to analyze and judge the stock market.

DMI index is a set of technical analysis tools that Oscar Wilde considered more successful and practical. Although its calculation process is complicated, the application of technical analysis software can make investors save the complicated calculation process, concentrate on mastering the true meaning revealed by indicators and understand its unique function of judging the market.

Different from other technical indicators, the kinetic energy of DMI indicators is mainly to identify market trends. In application, the judgment of DMI index mainly focuses on two aspects. On the one hand, it analyzes the relationship between the rising index +DI, the falling index -di and the average trend index ADX, on the other hand, it judges the trend and turning characteristics of the market. Among them, the trend relationship between +DI and -di curves is a signal to judge whether it can be bought or sold, and ADX is a signal to judge the future market development trend.

The first two are not clear.
