Instead, it’s best used as a support or resistance indicator, offering insight into potential price movements. Remember, successful trading strategies incorporate multiple indicators for decision-making. EMA trading includes using two EMA indicator crossovers for generating buy and sell signals.An EMA crossover method involves tracking two or more EMAs with various time frames to discover trade signals. When a shorter-period EMA passes over a longer-period EMA, it provides a bullish signal, indicating the possibility of an uptrend. When a shorter-period EMA passes below a longer-period EMA, it produces a bearish signal and indicates a probable downward trend.
What is an Example of a 200-day Exponential Moving Average (EMA) Calculation?
- An Exponential Moving Average (EMA) is a price smoothing technique that puts more weight on the most recent prices, making it more responsive to current market movements.
- However, it is important to note that relying only on the EMA buy and sell signals is not a sound trading strategy.
- For example, an 18.18% multiplier is applied to the most recent price data for a 10-period EMA, while the weight is only 9.52% for a 20-period EMA.
- Like all moving average indicators, EMAs are much better suited for trending markets.
- Robert Goodell and Charles Holt made significant contributions to the research of exponential smoothening.
- The EMA places more weight on recent price data, as a result of which it is more susceptible to recent spikes and changes in prices.
If both; the EMA and the demand or supply represent the same price increases the strength of the price to direct the further direction or trend of the script. The disadvantages of the EMA can be overcome by using other technical indicators along with the EMA. Other advantages of the EMA include its simplicity and comprehensibility as well as its ability to identify support and resistance levels. Traders can also identify potential entry and exit points as well as support and resistance levels by studying the EMA along with the price chart of the security.
How is EMA calculated?
- The methodology will be shared with the numbers folks below, but the main thing to understand is that Exponential Moving Averages will react to price changes faster than SMA.
- The image below shows what a price chart looks like when the EMA has been applied to the price chart of the Banknifty chart.
- Thirdly, the Exponential Moving Average can predict whether a trend will continue to rise or reverse.
- The exponential moving average is an improvement over the simple moving average, at least in terms of its relevance to investors and analysts.
Using EMA on a daily OHLC or Candlestick chart is a poor predictor of price trends and direction reversals, losing out to a buy-and-hold strategy 93% of the time. No, the exponential moving average indicator is inaccurate, averaging only a 7% win rate. When asset prices consolidate, the EMA causes many small losses, and good entry points are missed.
Since new data carries greater weight, the EMA responds more quickly than the SMA to price changes. Investors can easily combine the EMA with other trading indicators, such as MACD, RSI, and ADX. The chart above shows the 50-day EMA (yellow) and the 50-day SMA (green). Finally, candlestick patterns like bullish engulfing candlestick or hammer candlestick pattern become more meaningful when they occur near an EMA line, which often acts as dynamic support or resistance.

Calculating EMA
The ‘N’ in the formula above denotes the number of days for which the EMA is to be calculated. The formula for the multiplier has been substituted in the formula above for this version of the formula for EMA. The trendlines for each asset combine to create a visual effect known as a ribbon, making trends easier to spot. However, as the EMA is more responsive to recent changes, it can catch trends earlier compared to the SMA. It is essential to analyse the direction of the EMA in conjunction with the price position to accurately gauge the trend.
EMA Trend Filter Strategy
Although there are many options to choose from when considering the smoothing factor, most opt for a value of 2. This value gives more credibility to the most recent data points available. The more a trader increases the smoothing factor value, the more influence the most recent data will have on the moving average.
To calculate a 10-month EMA, set your chart to monthly and select your exponential moving average to be 10. Alternatively, on a daily chart, set the exponential moving average period to 200. There are approximately 20 trading days per month, multiplied by 10 months. There are four core moving averages; simple, exponential, weighted, and Hull moving averages. The exponential moving average is a subset of the moving average indicators.
The length you choose (like 10, 50, or 200 periods) depends on your trading goals. Shorter EMAs react faster but can be «noisy.» Longer EMAs are smoother but slower to respond. This makes EMA much quicker to react to new trends, reversals, or sudden price spikes.
The EMA and other types of moving averages also function as dynamic support and resistance levels. In an uptrend, the longer-term exponential moving average (e.g., a 50-day, 100-day, or 200-day moving average) may act as a support line, and in a downward trend, it can function as resistance. No, our research shows that exponential moving averages are not good indicators on any timeframes.
Trading the Best Exponential Moving Average Settings: Tested
Day traders typically go for shorter EMAs like the 9-day or 12-day EMA because they want to capture small, quick price moves in their day trading strategies. It is one of many different types of moving averages and has an easily calculable formula. All of this is true, however, the EMA strives to make this easier for traders. The EMA is unique because it places more emphasis on the most recent data.
How to read the EMA indicator?
Traders make the time frames for the EMA shorter during periods of market volatility so that even the indicator is more sensitive to the smallest of changes. The recent price movements are captured more accurately when the time period of the EMA is kept shorter. They are used to create indicators like the moving average convergence divergence (MACD) and the percentage price oscillator (PPO). In general, the 50- and 200-day EMAs are used as indicators for long-term trends. When a stock price crosses its 200-day moving average, it is a technical signal that a reversal has occurred. The Exponential Moving Average (EMA) is a refined moving average (MA) that emphasizes recent data points more heavily, offering a crucial edge in tracking price dynamics.
Similar to other moving averages, the EMA is a technical indicator that produces buy and sell signals based on data that shows evidence of divergence and crossovers from general and historical averages. Additionally, the EMA tries to amplify the importance that the most recent data points play in a calculation. An exponential moving average uses a chart timeframe in its calculation.
If you don’t have the previous day’s EMA value, you can start by calculating the SMA for an initial period as a base value for the EMA calculation. Yes, EMA’s can be used in combination with candlestick patterns to solidify a view about future direction of the script’s price. They may act as an added confirmation or confluence to have a stronger edge to generate a trading signal. Short-term investors don’t care what a stock was doing eight months ago or, for ema indicator that matter, how it will do eight months from now. For example, the Georgia Rural Health Innovation Center was able to track the incidence of COVID-19 cases in the region by charting the moving average of cases. It allowed the center to see past the peaks and valleys of daily case numbers and better anticipate the local arc of the pandemic.
The EMA indicator responds more quickly to fluctuations in price action when used in trading, which gives it an edge over the simple moving average. The indicators that work best with the EMA are momentum-based indicators. Lagging indicators only identify trends after a trend change has already occurred. Traders can get a more accurate and comprehensive result by combining two different types of indicators. An advance in price is accompanied by an advancing EMA denoted by a black arrow. Either the breakout trades or the retracements.The EMA, however, is a lagging indicator, and the signals are often more suited to confirming a market move or testing its strength.
The idea is to use two EMAs, a short-term EMA and a long-term EMA, and wait for them to cross over one another. Markets don’t always behave the same way, and neither should your EMA strategy. Your ideal EMA length should reflect your time horizon and risk tolerance. If you want to catch a trend early or avoid being the last one on a sinking ship, EMA gives you that edge. In this guide, we’ll break down how to calculate the EMA, compare it to SMA, explain when and how to use it, and walk through beginner-friendly strategies.

Backtesting the EMA indicator on 30 Dow Jones Industrial Average stocks over eight years resulted in an average 7% win rate, meaning it underperformed a buy-and-hold strategy 93% of the time. The exponential moving average (EMA) is a commonly used technical financial analysis tool that gauges a stock’s average price over a certain period. It provides insight into the direction of long-term asset price trends. If the price is above the EMA, it indicates a rising trend, potentially a suitable time to buy.
