Think about it this way: Of all moving averages, the exponential moving average is the most “in the moment” because it focuses on the most recent data points.ĮMAs are more complicated to calculate because prices closer to the present day receive more weight in the calculation than older prices. As a lagging indicator, the data used to create an SMA may already be outdated and less reliable by the time you’re able to view it in a trend line.īased on the SMA, the EMA gives more importance to recent prices, even if the rate of the decrease between the current price and its preceding price is inconsistent. If the line is trending up, the security is strengthening, whereas a downward trend shows a weakening of that security.Īlthough it can be a useful tool for evaluating a currency pair, the SMA also has limitations due to its reliance on historical data. SMAs are popular for their ability to easily illustrate the long-term trends of securities over time.

At the end of the new price period, that data is added to the calculation, and the oldest price data in the series is eliminated. Additional price data, such as the median price and opening price, can also be utilized. Generally speaking, an SMA is calculated using daily closing prices, but it is possible to use other time frames as well, even if they aren’t common. Notice how the 50-day line (in yellow) features more dramatic movements than both the 100-day (in brown) and the 200-day (in purple) lines:
Here’s a look at the 50-, 100-, and 200-day SMAs on a CHF/JPY chart. In general, longer-term SMAs are more slowly affected by dramatic price swings, whereas shorter-term SMAs will be faster to respond. The purpose of the SMA is to overlay a chart with long-term price trends to see how current prices compare to a long-term average. On a 20-day SMA, for example, the moving average is the average asset price in that particular date range.
An SMA is the average of the closing prices for the time period highlighted. This is the reasoning behind the name “simple” moving average. Long before the rise of internet-based trading, the simple moving average was already well established due to its ease of calculation. But there are differences between the two. Moving averages are one of the most popular tools that forex traders lean on when attempting to understand market movements because they add an extra layer to any chart analysis you’re conducting, highlighting exactly where the price action is happening.īased on pure popularity, the exponential moving average (EMA) and the simple moving average (SMA) are the two most common moving average tools.
