**What Is Exponential Moving Average (EMA)?**

Exponential Moving Average (EMA) is one of the essential technical indicator used widely by traders and investors .

Exponential Moving Average (EMA) gives more weighting to recent price data compared to Simple Moving Average (SMA) .

EMA is quite similar to SMA as it helps traders to measure trend direction of any security thus helps in predicting the future trend . Essentially its a trend direction indicator .

**(EMA) is used to know long-term trends. EMA gives more accurate recent price action compare to SMA . **

**This is because EMA uses the latest data point and the oldest data point gets the least observation .**

If you do not know about SMA and its calculation read our article on same . This will help you to clear fundamentals of (MA) Moving Averages .

**How to calculate Exponential Moving Average (EMA)**

You do not need to calculate EMA by yourself as most of the technical analysis software lets us drag and drop the EMA . This is just good to know info .

- First calculate the SMA

SMA = A1+A2+…+An / n

Where An= the price of an asset at period n

n= the number of total periods

- Than calculate the multiplier for weighting the EMA

Weighted multiplier =2÷(selected time period+1)

selected time period can be 10 day , 20 days , or 100 days depend upon your strategy .

- At end calculate the current EMA

EMA [today] = (Price [today] x K) + (EMA [yesterday] x (1 – K))

Where:

K = 2 ÷(N + 1)

N = the length of the EMA ( time period)

Price [today] = the current closing price

EMA [yesterday] = the previous EMA value

EMA [today] = the current EMA value

EMA generally uses the previous value of the EMA in its calculation. Therefore EMA includes all the price data within its current value.

**Another key point is the more data points you use, the more accurate your EMA will be**.

**How to Use EMA for Trading**

**EMA reacts faster**when the price is changing direction . To put it another way It may give you false or fake signals . - A trader might use crossovers of the 50 EMA by the 10 or 20 EMA as trading signals.
- The most generally used EMAs by traders are the 5, 10, 12, 20, 26, 50, 100, and 200.
- Where as the 50, 100 and 200 EMAs are considered to be useful for longer-term trend trading .
