EXPMA index (exponential moving average) is called exponential average index in Chinese, which is also a trend index. Its construction principle is to still carry out arithmetic average on the closing price of the price, and analyze it according to the calculation results, so as to judge the future trend of the price.

Compared with MACD indicator and DMA indicator, EXPMA indicator is determined as a trend analysis indicator because its calculation formula focuses on the weight of the current price, which overcomes the lag of MACD indicator signal in the use of price trends. At the same time, it also eliminates the signal lead of DMA index to price trend at a certain moment, which is a very effective analysis index.

Let's take a look at the calculation formula of EXPMA index to further understand the characteristics of the index: EXPMA = (closing price of the current day or period-EXPMA of the previous day or period)/n+EXPMA of the previous day or period, where the first EXPMA value of the previous period is the closing price of the previous period, and n is the number of days.

In fact, from the construction principle and use principle of EXPMA index, this index is closer to the moving average index, and because EXPMA index can play more intuitive and useful information than moving average index by setting parameters effectively.

In the technical analysis software, the EXPMA indicator consists of three lines, namely, price K line, short-term EXPMA line (represented by white line or other slightly shallow lines) and long-term EXPMA line (represented by yellow line or other slightly deep lines). On the coordinate diagram of EXPMA index, the ordinate represents the price of price operation, and the abscissa represents the time of price operation, which is consistent with the moving average index.

65438 +0. EXPMA indicator consists of EXPMA 1 (white line) and EXPMA2 (yellow line). When the white line crosses the yellow line from bottom to top, the stock price usually rises continuously, so the day when these two lines form a golden cross is a good time to buy.

2. When the stock price of a stock is far away from the white line, the stock price will fall back quickly and then move up along the white line, indicating that the white line is a great support point.

In the same way, when the white line breaks through the yellow line from top to bottom, the stock price has often turned, and the future will be dominated by decline, so the day when these two lines cross is the time to sell.
