A moving average (MA) is a common tool in technical analysis to track stock prices. Calculating a moving average helps smooth out price data by creating an updated average price, reducing the impact of short-term price changes. Simple moving averages (SMAs) use an arithmetic average of prices over a set period, while exponential moving averages (EMAs) give more weight to recent prices. In this blog, we’ll explain how to choose the right length for a moving average, provide examples, discuss common questions, and show how to apply them to your trading strategy.
The “length” or the number of periods used in a moving average calculation determines its appearance on a price chart.
This is crucial because it enables you to see how much detailed pricing matches your trading time frame.
As such, you might be thinking, “how do I use this for trading?”
There are two main types of moving averages:
The calculation method depends on the type of moving average. Below is an example using a simple moving average (SMA) with the following closing prices over 15 days:
A 10-day moving average would average the closing prices for the first 10 days as the first data point. The next data point would drop the earliest price, add the price on day 11, and then take the average.
In conclusion, knowing what moving averages mean is important for effective stock buying. By choosing appropriate length and type of moving average you can better analyze price trends and thus make more informed choices. When the moving average rises, it indicates the stock is in an uptrend. When it falls, it indicates a downtrend. Many prefer the exponential moving average over the simple moving average because it gives more importance to recent prices, making it more responsive to new information and trends.
A moving average shows the average change in a data series over time, indicating price trends for specific securities.
Moving averages help technical analysts detect and confirm changes in the momentum of a security’s price.
Examples of moving averages include the exponential moving average (EMA), which gives more weight to recent days, and the simple moving average, which averages prices equally.
