An exponential moving average (EMA) is a tool used in __technical analysis__ to track the price movements of an asset over a certain period. Unlike the __simple moving average__ (SMA), the EMA gives more importance to recent price data, making it more responsive to short-term market fluctuations.

This makes the EMA similar to the weighted moving average (__WMA__), which also gives more weight to recent data points. However, the EMA does so in an exponential manner while the WMA does so in a linear fashion.

As mentioned, the EMA gives exponentially more weight to recent price data. You can apply the EMA to different time frames, but to illustrate, we will consider each period as a full trading day. The EMA can be calculated with the following formula:Â

*The Closing Price*âis the last traded price of the period (day). So, if you use a daily chart, it is the daily close of the__candlestick__. If the current day is not closed yet, you can disregard it and use the previous periods instead.*The Previous EMA*is the EMA value for the previous period (day).**If you do not have the previous EMA, you can replace it with the simple moving average (SMA)**(see example below).*Multiplier = 2 / (n + 1).*It is the smoothing constant. Its value is determined by the number of periods you use (n).

Suppose we want to calculate a 10-day EMA. If there is no available EMA for the previous day, we will have to calculate the SMA first.

**1. Start with the SMA.**

Letâs assume that the respective closing prices from day 1 to 10 are 50, 57, 58, 53, 55, 49, 56, 54, 63, and 64.

Using the formula:

*SMA = (50 + 57 + 58 + 53 + 55 + 49 + 56 + 54 + 63 + 64) / 10 = 55.9*

**2. Determine the Multiplier.**

*Multiplier = 2 / (10+1) â= 2 / 11 = 0.1818*

**3. Compute the EMA.Â **

For the 11th day, letâs assume that the closing price is 60. Putting it all together in the EMA formula, we will have the following:

*EMA = (60 â 55.9) x 0.1818 + 55.9 = 56.64*

In crypto trading, EMAs can be used to spot market trends, reversals, and crossover signals.

The EMA is a technical analysis tool that assigns more weight to recent price data, offering a more responsive and accurate representation of the market trend. In crypto trading, EMAs can be used to spot trends, reversals, and crossover signals. However, as with any technical analysis indicator, there are no guarantees. Traders often combine multiple TA indicators to reduce risks.
