It’s a very popular technical indicator among traders that takes into account the average prices for a given period. It’s a way to smooth out price fluctuations and mitigate noise. Also used to define trends and as a trading signal for buyers and sellers.

The duration, or number of periods, represents the number of candles that will be used in the calculation of the MM. For example, a 30-period moving average involves averaging the last 30 candles on the chart.

Simple vs. Exponential Moving Averages

The most used MA are exponential and simple. The choice is up to the will of each one. If you prefer an indicator that responds more quickly to price changes, te better choise is the exponential moving average. EMA, from Exponential Moving Average, can identify changes in trends more quickly, but precipitation can be harmful and may show false signs of changes in trends.

The SMA, Simple Moving Average, is slower, can filter some of the false signals that the EMA presents. However, the excess of caution can offer a late entry in the trade and leave the entire result of the operation to the market.

Below the comparison of exponential moving averages (EMA) and simple (SMA).

Moving Average Crossovers

This powerful technical analysis tool can help you determine when a trend is about to end and reverse. The strategy consists simply of crossing two or more moving averages. This may be the first sign that the trend is ending or weakening.

In the example below, the 20-EMA crossed up the 30-EMA showing a buy signal. After a long period of high, 20-EMA crossed down the 30 EMA. Traders who entered with sell orders were able to take advantage of the bearish movement.

This strategy can be combined with trailing stops as prices move towards the expected result.What is Moving Average?

Dynamic support and resistance breakouts

When there is a dynamic level breakout, what was support becomes resistance and what was resistance becomes support. In the example below, prices were on an upward trend with dynamic support at EMA. After a downward movement, the break occurs and the EMA starts to act as price resistance offering several opportunities for entry on the short side.
