2. What is EMA

EMA refers to the exponential smoothing moving average, also called the EXPMA indicator. It is also a trend indicator and is an exponentially decreasing weighted moving average. , its construction principle is to still perform an arithmetic average on the closing price of the price, and conduct analysis based on the calculation results to determine the trend of future price trends.

Compared with the MACD indicator and DMA indicator, the EMA indicator focuses on the weight of the day's price (current period) in its calculation formula, which determines its use as a type of trend analysis indicator and overcomes the problems in use. The MACD indicator has a lagging defect in price trends. At the same time, it also eliminates to a certain extent the advance signal generated by the DMA indicator in price trends at certain times. It is a very effective analysis indicator.

3. Calculation principle of EMA

EXPMA= (closing price of the current day or current period - EXPMA of the previous day or previous period)/N+EXPMA of the previous day or previous period, among which, the first previous period EXPMA The value is the closing price of the previous period, and N is the number of days.

From the perspective of the construction principle of the EMA indicator and its usage principles, this indicator is closer to the moving average indicator, and because the EXPMA indicator can effectively set the parameters, it can play a better role than the moving average indicator. for intuitive and useful information.

In technical analysis software, the EMA indicator consists of three lines, the price K line, the short-term EMA line (represented by a white line or other slightly lighter lines), and the long-term EMA line (represented by a yellow line or other (represented by slightly darker lines). On the coordinate chart of the EMA indicator, the vertical axis represents the price of the price operation, and the horizontal axis represents the time of the price operation. This is also consistent with the moving average indicator.
