How to Trade Simple Moving Averages


Historically, when the price of the S&P 500 falls below its 200 DMA, it usually means a recession is imminent. Some investors use that signal to either hedge their portfolio or sell out completely. All expressions of opinion are subject to change without notice in reaction to shifting market conditions.

  • A technical tool known as a simple moving average1 (SMA) crossover can help traders identify the lion’s share of a trend.
  • These principles are intended to help traders interpret the potential direction of a trend, not to definitively call its direction.
  • Short-term averages respond quickly to changes in the price of the underlying security, while long-term averages are slower to react.
  • Technical trading is a lot like surfing—learning to read the “waves” can help you determine their strength and direction.
  • Securities sometimes move in price cycles and repeat behavior, but past trends that are plotted with a moving average may have no relationship to future movements.

Now, as with almost any other forex indicator out there, moving averages operate with a delay. The calculation for EMA puts more emphasis on the recent data points. When the simple moving median above is central, the smoothing is identical to the median filter which has applications in, for example, image signal processing. The Moving Median is a more robust alternative to the Moving Average when it comes to estimating the underlying trend in a time series.

Simple Moving Average vs. Exponential Moving Average

When generating the SMA, traders must first calculate this average by adding prices over a given period and dividing the total by the total number of periods. Trend followers want to buy stocks that are trending up and sell stocks that are trending down. If the moving average is going up, it is possible that the stock is trending up.


It can serve as a benchmark when comparing another moving average, such as the 50-day moving average, to it. If the 50-day moving average is above the 200-day moving average, then the stock is considered to be in a bullish position. An EMA may work better in a stock or financial market for a time, and at other times, an SMA may work better.

Simple Moving Average (SMA) Explained

Longer-term traders tend to rely on SMAs since these investors aren’t rushing to act and prefer to be less actively engaged in their trades. Note that with an EMA, each data point included in the average decreases in weight over time, until it is ultimately removed as new data points are added that carry higher weights. So in the case of a 10-day EMA, the weight of a new data point on day one would drop to just 6.67% of its initial weight after five closing prices. The exponential moving average (EMA) focuses more on recent prices than on a long series of data points, as the simple moving average required.

In contrast, the Moving Median, which is found by sorting the values inside the time window and finding the value in the middle, is more resistant to the impact of such rare events. As a result, the Moving Median provides a more reliable and stable estimate of the underlying trend even when the time series is affected by large deviations from the trend. Additionally, the Moving Median smoothing is identical to the Median Filter, which has various applications in image signal processing. 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. Remember, longer the time frame, the lesser the number of trading signals.

Calculating the Simple Moving Average (SMA)

A 10-day moving average would average out 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, then take the average, and so on. Likewise, a 50-day moving average would accumulate enough data to average 50 consecutive days of data on a rolling basis. A simple moving average (SMA) calculates the average of a selected range of prices, usually closing prices, by the number of periods in that range. The weighted moving average (WMA) gives you a weighted average of recent prices, where the weighting decreases with each previous price. This works similarly to the EMA, but you calculate the WMA differently.

You may find that, for each market, you need to adjust your settings slightly. A 50-period SMA may provide great signals on one stock, for example, but not on another. A 20-period EMA may help isolate the trend on one futures contract but not another. All of the moving averages are just tools, and interpreting features of commercial paper them is up to the trader, because no indicator works well all the time or in all market conditions. The Simple Moving Average (SMA) is a widely used technical indicator in stock analysis. It is calculated by taking the average of the closing prices of a stock over a certain period of time.

Remember the basic assumption of technical analysis – markets discount everything. This means the latest price you see (on 28th July) discounts all the known and unknown information. This also implies the price on 28th is more sacred than the price on 25th. Moving averages can be calculated for any time frame, from minutes, hours to years.

The faster-moving EMA signals trouble quicker than the SMA, and so the EMA trader gets out of harm’s way quicker, saving that person time and money. Moving averages work quite well in strong trending conditions but poorly in choppy or ranging conditions. Adjusting the time frame can remedy this problem temporarily, though at some point, these issues are likely to occur regardless of the time frame chosen for the moving average(s).

The 10-day moving average plotted on an hourly chart is frequently used to guide traders in intraday trading. Moving average crossovers are a popular strategy for both entries and exits. While this may appear predictive, moving averages are always based on historical data and simply show the average price over a certain time period.

Looking at when the lines cross over, it helps certain traders time their trades. The most popular moving averages for longer-term investors are the 50-day and 200-day SMAs. For shorter-term investors, the 10-day and 20-day SMAs are often used as well.

It is once again because the 5-day SMA is a shorter period, which follows the price more closely, whereas the 10-day SMA considers more historical data. Many people (including economists) believe that markets are efficient—that is, that current market prices already reflect all available information. If markets are indeed efficient, using historical data should tell us nothing about the future direction of asset prices.

In such cases, adding a slightly longer SMA for comparison—such as the 200-day SMA—might make it easier to assess whether the stock has truly broken through its support or resistance. The simple moving average is a smoother representation of a stock price’s trend and the other two types of moving average provide more jerky, quick signals. Exponential moving average (EMA) and weighted moving average (WMA) are similar to the simple moving average, but both are adjusted to give more impact to more recent trading days. Moving averages are calculated to identify the trend direction of a stock or to determine its support and resistance levels.

Hence as per the trading system rule, we initiate a fresh long position. An EMA can provide buy signals when combined with Keltner Channels, an indicator with a high, average, and low price that creates a “channel” on a chart. A strategy may include buying near the EMA when the trend is up, and the price is pulling back from the top of the Keltner Channel. As with the SMA, charting platforms do all of the EMA calculations for you.
