You should consider whether you understand how this product works, and whether you can afford to take the high risk of losing your money. Both exponential and simple moving averages, while different in their computation of value, may be used in similar manners. A straightforward way to utilise moving averages in one’s trade is to use two moving averages of different time frames in conjunction.
- MAs have enjoyed such popularity because they provide the clearest method to identify a trend, smoothing the erratic data to see the trend more clearly.
- This would mean that the spike on Day 2 would be of lesser value and wouldn’t have as big an effect on the moving average as it would if we had calculated for a simple moving average.
- Ultimately it is a hard decision that calls for extensive back-testing to decide on the proper length.
- The preferred number and type of moving averages can vary considerably between traders, based on investment strategies and the underlying security or index.
Reduction in the weight of price values of currency pairs as they move away resolves the SMA’s problems, where dropping the last price can affect the indicator more than adding the new one. We are now moving on from Simple Moving Averages (SMA) to a bit less simple moving average indicator, the Exponential Moving Average (EMA). But before we do that, let’s explore the reasoning behind why SMAs simply aren’t enough. To overcome lag, we decrease length or use EMA/LMMA calculation methods or use the single (and triple) MA crossover techniques, all of which creates more noise. To overcome noise, we increase the length or use SMA/SMMA calculation methods or the dual moving average technique, all of which creates more lag.
Uptrends, conversely, show shorter moving averages crossing above longer moving averages. In these circumstances, the short-term moving averages act as leading indicators that are confirmed as longer-term averages trend toward them. For ease of analysis, keep the type of moving average consistent across the ribbon—for example, use only exponential moving averages or simple moving averages. Traders who employ technical analysis find moving averages very useful and insightful when applied correctly. However, they also realize that these signals can create havoc when used improperly or misinterpreted. All the moving averages commonly used in technical analysis are lagging indicators.
Using EMA in a Forex Trading Strategy
When the shorter MA comes from below and crosses above the longer MA line, this is considered a golden cross or bullish cross (and it’s time to buy, as in our previous strategy). When the shorter MA comes from above and crosses to below the longer MA, this is a death cross or bearish cross and considered a sign to sell. 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.

When the line is below the price in an upward trend, it serves as support, recency bias example and when it is above the price in a downward trend, it serves as resistance. When the price moves below the line (2), it is a bearish signal indicating that the asset could fall further, and you might use this as an indicator to sell.
How to Create a Moving Average Ribbon
You can customise your own ribbon by choosing how many MA lines you want and whether they should be SMAs or EMAs. When the current price of that forex market crosses your MA line from below, this is known as a ‘golden cross’ or a bullish cross, and it could be a sign that it’s time to buy. When the price crosses your MA line from above, it’s called the ‘death cross’ or bearish cross and it could be a sign to sell.
It makes it easier to see a pattern forming over time and helps predict future prices. There are several types of “Moving Average” indicators, one “smoother” than the other. The smoother the moving average line the less detailed the picture that is formed and the slower to react to price movement. The “Simple Moving Average Indicator” doesn’t take spikes into account and therefore does not give as accurate a picture as the “Exponential Moving Average”. Weighted moving averages assign a heavier weighting to more current data points since they are more relevant than data points in the distant past.
In our above example, the chart contains two EMA lines of differing periods. These two lines are often called a “ribbon”, but a single line can also be beneficial when planning a forex trading strategy. The exponential moving average (EMA) is one of the most commonly utilized forex trading tools. Traders use the EMA overlay on their trading charts to determine the entry and exit points of a trade based on where the price action sits on the EMA. If it is high, the trader may consider a sale or short sale, and conversely if it is low, a buy. The preferred number and type of moving averages can vary considerably between traders, based on investment strategies and the underlying security or index.

Conversely, if the EMA acts as resistance, you can sell the asset when it reaches the line expecting the price to bounce off the EMA.

The most commonly used type of moving average, the simple moving average (SMA) is calculated by adding and then averaging a set of numbers representing the market. The SMA is by far the more popular mode, and it is considered highly useful because of its smoothing effect. However, markets react to news and current events, which can mean that an SMA can only give you half the picture. Enter exponential moving averages (EMA), which also calculate a market’s average price but gives far more weight to the most recent price changes and less weight to older ones. In this example, the recent data point was given the highest weighting out of an arbitrary 15 points.
As the exponential MA line on a chart follows an asset price more closely, it reduces the lag seen in the SMA and helps traders to capitalise on trading opportunities as quickly as possible. Given the greater influence that recent data has on the EMA, recency bias is present here. With the stock market, this can be dangerous when prices are at extremes. The EMA may fuel further buying interest in the market during a time when prices are already in extreme overbought condition, overdue for a pullback. It is important that one exercise their discretion when using any tools in their trading. Back testing would be one way to improve the validity of one’s trading strategy using tools such as the EMA.
Vulnerabilities of the Moving Average
Many traders believe that new data better reflects the current trend of the security. At the same time, others feel that overweighting recent dates creates a bias that leads to more false alarms. The EMA would put more weight on the more recent prices, which would be Days 3, 4, and 5. This means that the previous day has more weight than the first trading day. It also means that the spike on Day 2 price action would be of lesser value and wouldn’t have as big an effect on the moving average as it would if we had calculated for a simple moving average. The smooth alliance is the SMA and SMMA, in that both try to smooth out the noisy, erratic behavior of the market in order to better see the underlying trend.

The lower value from the weighted average above relative to the simple average suggests that recent selling pressure could be more significant than some traders anticipate. For most traders, the most popular choice when using weighted moving averages is to use a higher weighting for recent values. EMAs are frequently used in conjunction with other indicators to confirm and validate large market moves. The EMA is more useful for traders who trade intraday and fast-moving markets. If an EMA on a daily chart indicates a strong rising trend, an intraday trader’s strategy may be to solely trade on the long side.
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 50-day SMA crosses below the 200-day SMA, and it is considered a bearish signal. An opposite indicator, known as the golden cross, is created when the 50-day SMA crosses above the 200-day SMA, and it is considered a bullish signal.
