For example, we might take a moving average of order 4, and then apply another moving average of order 2 to the results. In the following table, this has been done for the first few years of the Australian quarterly beer production data. The values in the last column are obtained by taking a moving average of order 2 of the values in the previous column.
For example, the first two values in the 4-MA column are The first value in the 2x4-MA column is the average of these two: Other combinations of moving averages are also possible. In general, an even order MA should be followed by an even order MA to make it symmetric. Similarly, an odd order MA should be followed by an odd order MA. The most common use of centred moving averages is for estimating the trend-cycle from seasonal data.
Other choices for the order of the MA will usually result in trend-cycle estimates being contaminated by the seasonality in the data. Select basic ads. Create a personalised ads profile.

Thus, the weighted moving average is a more accurate measure of recent price action -- information that is more useful for many traders than a simple moving average. Many trading platforms allow you to adjust a weighted moving average. By changing the weight to change the importance to recent prices, you can develop your own trading system.
There are no magic formulas or systems that reliably predict stock prices. The functions of an EMA and a WMA are similar, they rely more heavily on the most recent prices and placing less value on older prices. All moving averages have a significant drawback in that they are lagging indicators. Since moving averages are based on prior data, they suffer a time lag before they reflect a change in trend.
A stock price may move sharply before a moving average can show a trend change. A shorter moving average suffers from less lag than a longer moving average. Still, this lag is useful for certain technical indicators known as moving average crossovers.
The technical indicator known as the death cross occurs when the day SMA crosses below the day SMA, and it is considered a bearish signal. An opposite indicator, known as the golden cross , is created when the day SMA crosses above the day SMA, and it is considered a bullish signal. Yahoo Finance.
