Before reading this lesson, you should have previously read through:

The moving average is one of the most commonly used

and they are generally used for two things: determining the market conditions, and entering and exiting a trade.## What is a moving average indicator?

A moving average is a display of the average price of an

over a specific period of time. It is displayed as a line on the chart. The moving average line is constructed by taking the average price over a specific number of periods. Each average price is then plotted on the ; usually it is the closing price of each candle that is used.**moving average**is an indicator that displays the average price of an instrument over a specific period of time.

Let's consider a 20 period moving average on a five minute chart. Each point of the moving average is calculated from the average closing price of the last 20 five minute candles. As each five minute candle forms, the moving average will continue to plot the average closing price of the most recent 20 periods. The result is a continuous line, as seen below.

number_1 - Simple moving average over 20 periods

A moving average is not always 20 periods, it is customisable, and so you can choose whichever period you would like.

For example, the chart below is displaying a 200 period moving average, so the calculation is based on the previous 200 periods from the current candle.

The moving average is used to smooth the

by producing a single line that makes it easier for traders to interpret market information, such as current direction.Looking at the chart below, the **trend direction and strength can be identified** by observing the slope and the angle of a moving average. If the moving average is very steep then the price is in a strong trend.

number_1 - Steep angle to the upside denoting a strong trend

number_2 - Flat angle in a denoting a weak bullish trend

number_3 - Steep angle to the upside denoting a strong bullish trend

A trader can also use a moving average to make decisions as to **which way to trade** by observing whether the price is above or below a moving average.

If the price is **above** a moving average, it is higher than the recent price averages and thus it stands to reason that the price is **moving up**. Similarly, if the price is trading **below** a moving average it can be interpreted as the price **moving down.**

Take note that this is **subjective,** because any moving average is relative to the period for which you are observing the trend, and further moving averages on the chart must also be taken into consideration.

Take, for example, the information in the chart below. If the price is trading above a 20 period moving average, you might determine that the price is currently trending to the upside. However, the price could also be trading below the 200 period moving average, meaning the price is in an overall long term

.number_1 - 20 period moving average denotes short term uptrend

number_2 - 200 period moving average denotes that we are still in a long term downtrend

A trader can use these moving averages to not only determine what trend the price is currently in for the shorter term, but to also determine the overall longer term trend.

## Using multiple moving averages to define a clear trend

By using multiple moving averages, a trader can determine a clear downtrend or

.**multiple moving averages**means that you can determine clear uptrends and downtrends.

number_1 - 200 period moving average

number_2 - 50 period moving average

number_3 - 20 period moving average

number_4 - 10 period moving average

There are no specific rules when choosing the number of periods a trader should apply when using a moving average indicator, the choice is purely down to the individual.

The **shorter the period** of the moving average, **the more quickly it will change** with price, but will provide less reliable signals than a longer period moving average. Similarly, a **longer** period moving average will provide **more reliable signals,** but will react to price changes much more slowly.

**less reliable**signals. The longer the period, the

**more reliable**the signal, but prices changes much more slowly.

For example, the 10 period moving average takes into account the last 10 periods and will therefore react to the change in price direction very quickly. The downside to this is that the trader may often receive false signals in the change of the trend because short term spikes in price can occur.

On the other end, the 200 period moving average takes longer to react and produces fewer false signals. The downside is that because the reaction is slower, the signals that are produced are much less frequent.

In the chart below we can see how the 10 period moving average (purple) changes direction in line much more quickly with the change in price, while the 200 period moving average (red) does not.

number_1 - 200 period moving average has not yet registered the new move

number_2 - 10 period moving average is in a downtrend

## Different moving average types

There are four types of moving averages:

- Simple
- Exponential
- Linear weighted
- Smooth weighted

The fundamental difference between these types of moving averages is how they are calculated. Due to this, they appear differently on the price chart.

The simple moving average uses each period with equal weighting in its calculations. The exponential, linear and smooth weighted averages emphasise the most recent periods in the calculations. Consider the 50 period moving average on the following chart in conjunction with the different moving average types, you can see the difference in appearance.

number_1 - Linear weighted moving average

number_2 - Exponential moving average

number_3 - Simple moving average

number_4 - Smoothed moving average

## Using moving averages as support and resistance

**resistance**; if it is above, it can act as

**support**.

Moving average indicators can also be used as

or for possible entry or exit points in the markets. What this actually means is that when the price comes into contact with the moving average on the price chart, traders watching the charts will then enter orders to either or . This essentially works in the same way as a horizontal support or resistance line.If the price is below the moving average, then the moving average will act as resistance; if the price is above the moving average, it will act as support.

Moving averages are dynamic support and resistance because they change as the price moves.

number_1 - Simple moving average

number_2 - Price action uses moving average as resistance

## Moving average crossovers

Moving average crossovers can be used to determine when a trend has changed direction. The concept uses two moving averages of different periods to show the short term and the longer term trend in the price.

**crosses below to above**a long term moving average, this can signal that the trend is changing direction to the

**upside**. Likewise, if a short term moving average crosses

**above to below**a long term moving average, this can signal a change to the

**downside**.

When the shorter term moving average and the longer term moving average cross each other, this can show that the trend has started to change direction. When observed, traders can use this to appropriately time entries and exits from the market.

The chart below shows what it looks like when the trend changes from a downtrend to an uptrend. We can identify it as such because the fast moving average, which was below the slow moving average, **crossed** the slow moving average. When this happened, a clear trend change to the upside in the price action could be seen.

number_1 - Slow moving average

number_2 - Fast moving average

number_3 - Fast moving average crosses over the slow moving average
