What is EMA and how to calculate?

Traders use this to smooth the variations in data to determine the underlying trend. EMA leads to calculating the average of the values by looking back at a recent number of data points. EMA is adding a portion of the current price. To a part of the value of the previous moving average.
Usually, EMA calculate at the time (t), and the formula of an exponential moving average is as follows:

EMAt= ɑ x current price + (1- ɑ) x EMAt-1

ɑ is a smoothing constant in which the value between 0 and 1.
EMAt-1 is the EMA for the previous period. So, to calculate EMA for a specific time require the previous calculations of EMA. If we calculate daily EMA, we can derive the current value of the previous day’s EMA.

Use EMA with the trend 

As mentioned earlier, a more effective way of reading the EMA cross is by using a double exponential moving average combination. It means, one short-term and one long-term EMA. This strategy creates a trading signal when the shorter EMA crosses the longer one.
If the short term EMA crosses above a long time EMA, it is an uptrend market, and if the short term EMA crosses below the long term EMA, it usually is known as a downtrend.
As an example, a longer-term trader may use 12-day EMA as a short term average and 26-day EMA as the long-term trend line. In this situation, the trader will buy when 12-day EMA crosses above the 26-day EMA while selling when the 12-day EMA crosses below the 26-day EMA.

This crossover strategy had mostly used before the computerized charts invented. But after the digital operations came into the market traders can access charts and indicators. So now this uses to indicate the uptrend and the downtrend in trading. So, now the most popular EMA strategy in trading is pullbacks.
