The cryptocurrency market is highly speculative in nature, which usually leads to exaggerated levels of volatility. To compensate, investors need to use technical indicators that adapt to the volatility of cryptocurrencies. One such indicator is the exponential moving average (EMA), which is designed to smooth out the effects of price volatility.
Among technical indicators, the moving average (MA) is one of the most commonly used tools to indicate overall trend direction. The exponential moving average focuses on the most recent price data, which is important when trading in the volatile crypto environment. In this article, we’ll discuss how the EMA is used in crypto trading, and we’ll outline different ways on how to use EMA indicator, along with practical trading examples.
What Is an Exponential Moving Average?
An exponential moving average is a technical indicator that gives greater weighting to recent prices in its calculation. As a result, EMA responds more quickly to the latest price changes, as compared to a simple moving average (SMA), which has a bigger lag.
The primary aim of the EMA is to smooth out the price and remove short-term price fluctuations.
Most investors focus on SMA, which shows the average price of a specific number of candles. If the current price moves above the average, bulls are stronger than bears. On the other hand, changing direction might indicate a trend change. However, EMA gives more weight to current data because its formula more closely follows the price.
EMA Calculation
The mathematical formula for calculating EMA builds upon its previous values. Therefore, all price data remains up-to-date so that the newest data has greater impact than the older price data.
EMA = Y + [K × (X − Y)]
Where:
X = Current price
Y = Previous period’s EMA (SMA is used for the first period’s calculations)
K = Exponential smoothing constant (this gives the appropriate weight to the most recent prices, utilizing the specified period in the MA)
The EMA clarifies price action for traders by reducing the lag in the price chart. As a result, it smoothes the price and makes the trend more reliable and accurate than with the traditional moving average. However, its greater price sensitivity may at times confuse traders. Therefore, the ideal approach is to use other technical indicators in addition to EMA in order to determine the most accurate buying point.
Strengths and Weaknesses of EMA
As with all technical indicators, moving averages cannot be the ultimate solution for trading cryptocurrencies. Therefore, investors should understand these indicators’ strengths and weaknesses before using them to make trading decisions.
Strengths of the Exponential Moving Average
- EMA shows a more accurate result than SMA because it focuses on the most recent price changes.
- EMA works well for finding the current market trend. Investors can define the possible market movement by looking at whETHer or not the price is above the EMA.
- Besides indicating trend direction, EMA works as both a dynamic support and resistance level.
- Although EMA is a trend trading indicator, investors can use it to find possible reversal points. The larger the gap between the price and the EMA increases, the higher the reversal possibility.
- Investors can easily combine the EMA with other trading indicators, such as MACD, RSI, stochastic and ADX.
- The golden cross trading strategy uses the 50-period EMA and 200-period SMA to show both short-term and long-term trading sentiment.
Weaknesses of the Exponential Moving Average
- EMA is just one part of a trading strategy, and investors cannot rely solely upon it.
- Although EMA lags less than SMA, it still has some lag, as do other technical indicators.
- In cryptocurrency trading, sharp bullish movement is common, which is not identifiable using the EMA.
- Within the volatile crypto market structure, EMA often provides false signals.
How is EMA Used in Crypto Trading
EMA works like other moving average indicators, where the primary aim is to identify the market trend. If a crypto asset is within an uptrend, the price will be above the EMA. For a bearish trend, the price should remain below the EMA. On the other hand, a contraindication of the EMA would represent a correction in a trend. The three phases of a trend can easily be found using the EMA:
- Price is stable above the EMA: uptrend
- Price is stable below the EMA: downtrend
- Price becomes unstable at the EMA: correction.
In cryptocurrency trading, investors should find a stable price above the EMA to open a buy position. In addition, a trend trader should understand how to gauge the strength of a trend.
Based on the EMA value, we can define a market trend as follows:
1. EMA 12 to 26 days: suitable for finding short-term trends
2. EMA 50 to 200 days: suitable for finding medium- and long-term trends
Long-term traders and HODLers should use an EMA of 50–200 days to identify the long-term price direction in cryptocurrency trading. On the other hand, the short-term trend is suitable for opening trades. However, the period of the EMA depends on the trader’s choice and flexibility. Fortunately, this can be easily adjusted to fit your trading plan.
How to Use EMA Indicator to Trade
There are many ways to trade cryptocurrencies using EMA. However, professional traders like to keep the system simple, using it where profitability is high.
Trend Trading
Trend trading is the basic way to identify where most market participants are most comfortable owning the asset at the current price. In this mETHod, the combination of EMA and SMA has higher probability rates. We can use a 200 SMA for long-term trends and a 50 EMA for short-term trends. Therefore, crypto investors should buy once the price moves above both the 200 SMA and 50 EMA.
Dynamic Support And Resistance
Another approach is to use EMA as a dynamic support or resistance level. One of the biggest drawbacks of static S/R is that it remains fixed at a given level. On the other hand, dynamic S/R levels move with the price and can react immediately.
Buying a crypto asset from the dynamic support level has a better risk-to-reward ratio. The 50-day and 200-day moving averages can be used to identify dynamic support and resistance zones from which prices are more likely to react. Therefore, this mETHod is suitable for finding near-term reversal points toward the trend.
EMA Crossover Trading
When one moving average moves above another, it creates a profitable trading opportunity. One of the most effective crossover strategies is known as the golden cross. When the 50 EMA moves above the 200 SMA, it indicates that short-term bulls are becoming more aggressive, while long-term traders are still bullish. This is applicable in any time frame from one minute to one week.
Closing Thoughts
To summarize how to use EMA indicator, using it to determine entries can be profitable if traders combine it with other trading tools. EMA remains popular among traders because it places more weight on the latest price data, lagging less than other technical indicators. Similar to all moving averages, EMA works best in the midst of a strong trend in the market.
