How To Use a Moving Average to Buy Stocks

A 20-day moving average will provide many more reversal signals than a 100-day moving average. The 20-day may be of analytical benefit to a shorter-term trader since it follows the price more closely and therefore produces less lag than the longer-term moving average. These lengths can be applied to any chart time frame (one minute, daily, weekly, etc.), depending on the trader’s time horizon. The time frame or length you choose for a moving average, also called the “look back period,” can play a big role in how effective it is. The triple exponential moving average smooths price fluctuations, making it easier to identify trends. Moving averages are widely used in technical analysis, a branch of investing that seeks to understand and profit from the price movement patterns of securities and indices.

Moving averages can be calculated for any time frame, from minutes, hours to years. Any time frame can be selected from the charting software-based of your requirements.

John Murphy’s Technical Analysis of the Financial Markets contains a chapter devoted to moving averages, their various uses and their pros and cons. In addition, Murphy shows how moving averages work with Bollinger Bands and channel-based trading systems. Other weighting systems are used occasionally – for example, in share trading a volume weighting will weight each time period in proportion to its trading volume. Some computer performance metrics, e.g. the average process queue length, or the average CPU utilization, use a form of exponential moving average. A major drawback of the SMA is that it lets through a significant amount of the signal shorter than the window length. This can lead to unexpected artifacts, such as peaks in the smoothed result appearing where there were troughs in the data.

• That’s because it represents the current price action with more accuracy.
• That said, it could be generally agreed that EMA gives more weight to recent prices, and therefore, it is most useful as a short-term trading indicator.

• Before we move on, just remember that moving averages smooth price data to form a trend-following technical indicator.
• It can be shown that if the fluctuations are instead assumed to be Laplace distributed, then the moving median is statistically optimal.
• However, whereas SMA simply calculates an average of price data, EMA applies more weight to data that is more current.

Instead of exact levels, moving averages can be used to identify support or resistance zones. Moving averages are typically based on price data, and specifically closing price data.
