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 line) and long-term EXPMA line (represented by yellow line or other slightly deep line). 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.
