EMA gives the meaning of Exponential Moving Average, and this is one of the most commonly used forex trading strategies. Simple Moving Average (SMA) This is a result of the This helps to determine entry and exit points of the trade base on the place of price action sit on the trading chart. When a forex trading using this EMA, it relies on selecting shorter-term EMA and a longer-term EMA. Then the trade base on the position of the short term EMA concerning the long term EMA. After considering all these things, a trader enters to buy orders when the short term EMA crosses over the long term EMA. Or else, traders move into sell orders when the short period EMA crosses below the long term EMA. This strategy gives more weight to the recent data and also EMA reacts faster to current prices than SMA.

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.
