Chartists should experiment with both types of moving averages as well as different timeframes to find the best fit. All moving averages take the average of a specified number of prior data points, but each type of moving average weights those data points differently.

A simple moving average is formed by computing the average price of a security over a specific number of periods. Most moving averages are based on closing prices; for example, a 5-day simple moving average is the five-day sum of closing prices divided by five. As its name implies, a moving average is an average that moves.

Old data is dropped as new data becomes available, causing the average to move along the time scale. The example below shows a 5-day moving average evolving over three days. The first day of the moving average simply covers the last five days. The second day of the moving average drops the first data point 11 and adds the new data point The third day of the moving average continues by dropping the first data point 12 and adding the new data point In the example above, prices gradually increase from 11 to 17 over a total of seven days.

Notice that the moving average also rises from 13 to 15 over a three-day calculation period. Also, notice that each moving average value is just below the last price. For example, the moving average for day one equals 13 and the last price is Prices the prior four days were lower and this causes the moving average to lag. Exponential moving averages EMAs reduce the lag by applying more weight to recent prices.

The weighting applied to the most recent price depends on the number of periods in the moving average. You need far more than 10 days of data to calculate a reasonably accurate day EMA. There are three steps to calculating an exponential moving average EMA. First, calculate the simple moving average for the initial EMA value. An exponential moving average EMA has to start somewhere, so a simple moving average is used as the previous period's EMA in the first calculation.

Second, calculate the weighting multiplier. Third, calculate the exponential moving average for each day between the initial EMA value and today, using the price, the multiplier, and the previous period's EMA value.

The formula below is for a day EMA. A period exponential moving average applies an A period EMA can also be called an A period EMA applies a 9. Notice that the weighting for the shorter time period is more than the weighting for the longer time period.

In fact, the weighting drops by half every time the moving average period doubles. If you want to use a specific percentage for an EMA, you can use this formula to convert it to time periods and then enter that value as the EMA's parameter:. Below is a spreadsheet example of a day simple moving average and a day exponential moving average for Intel. The SMA calculation is straightforward and requires little explanation: the day SMA simply moves as new prices become available and old prices drop off.

The exponential moving average in the spreadsheet starts with the SMA value After the first calculation, the normal EMA formula is used. Each previous EMA value accounts for a small portion of the current value. This is not always practical, but the more data points you use, the more accurate your EMA will be.

The goal is to maximize accuracy while minimizing calculation time. The spreadsheet example below goes back 30 periods. With only 30 data points incorporated in the EMA calculations, the day EMA values in the spreadsheet are not very accurate. On our charts, we calculate back at least periods typically much further , resulting in EMA values that are accurate to within a fraction of a penny. Click here to download this spreadsheet example. When adding a moving average to your chart, the first choice to make is whether to use an exponential or a simple moving average.

Even though there are clear differences between simple moving averages and exponential moving averages, one is not necessarily better than the other. Choosing the right type of moving average depends on your trading objectives.

Exponential moving averages have less lag and are therefore more sensitive to recent prices - and recent price changes. Exponential moving averages will turn before simple moving averages. Simple moving averages, on the other hand, represent a true average of prices for the entire time period. As such, simple moving averages may be better suited to identify support or resistance levels.

The length of the moving average depends on the trader's time horizon and analytical objectives. Short moving averages periods are best suited for short-term trends and trading. Chartists interested in medium-term trends would opt for longer moving averages that might extend periods. Long-term investors will prefer moving averages with or more periods. Some moving average lengths are more popular than others. The day moving average is perhaps the most popular. Because of its length, this is clearly a long-term moving average.

Next, the day moving average is quite popular for the medium-term trend. Many chartists use the day and day moving averages together. Short-term, a day moving average was quite popular in the past because it was easy to calculate. One simply added the numbers and moved the decimal point. Moving averages are typically based on price data, and specifically closing price data. However, this indicator can be applied to other types of price data open, high, or low , volume data, or even other indicators.

Moving averages can be used to identify the trend, as well as support and resistance levels. Crossovers with price or with another moving average can provide trading signals. Chartists may also create a Moving Average Ribbon with more than one moving average to analyze the interaction between multiple MAs at once.

The direction of the moving average conveys important information about prices, whether that average is simple or exponential. A rising moving average shows that prices are generally increasing. A falling moving average indicates that prices, on average, are falling. A rising long-term moving average reflects a long-term uptrend. A falling long-term moving average reflects a long-term downtrend. The chart above shows 3M MMM with a day exponential moving average. This example shows just how well moving averages work when the trend is strong.

These lagging indicators identify trend reversals as they occur at best or after they occur at worst. Notice that the day EMA did not turn up until after this surge. Once it did, however, MMM continued higher the next 12 months. Moving averages work brilliantly in strong trends. Two moving averages can be used together to generate crossover signals. Double crossovers involve one relatively short moving average and one relatively long moving average. As with all moving averages, the general length of the moving average defines the timeframe for the system.

A bullish crossover occurs when the shorter moving average crosses above the longer moving average. This is also known as a golden cross. A bearish crossover occurs when the shorter moving average crosses below the longer moving average. Moving average crossovers produce relatively late signals. After all, the system employs two lagging indicators.

The longer the moving average periods, the greater the lag in the signals. These signals work great when a good trend takes hold. However, a moving average crossover system will produce lots of whipsaws in the absence of a strong trend. There is also a triple crossover method that involves three moving averages. Again, a signal is generated when the shortest moving average crosses the two longer moving averages.

A simple triple crossover system might involve 5-day, day, and day moving averages. The black line is the daily close. Using a moving average crossover would have resulted in three whipsaws before catching a good trade. This cross lasted longer, but the next bearish crossover in January 3 occurred near late November price levels, resulting in another whipsaw. This bearish cross did not last long as the day EMA moved back above the day a few days later 4.

There are two takeaways here. First, crossovers are prone to whipsaw. A price or time filter can be applied to help prevent whipsaws. Second, MACD can be used to identify and quantify these crossovers. MACD 10,50,1 will show a line representing the difference between the two exponential moving averages.

Simple moving averages (SMAs) are a true average of prices over the specified timeframe, while exponential moving averages (EMAs) give more weight to more. The Weighted Moving Average (WMA) places more emphasis on recent prices than on older prices. Each period's data is multiplied by a weight, with the weighting. A Moving Average (MA for short) is a technical indicator that averages a currency pair's price over a period of time.
