How to calculate exponential moving average
The exponential moving average (EMA) is a widely used technical indicator that tracks the performance of financial assets, such as stocks or currencies. Unlike the simple moving average (SMA), EMA assigns more weight to recent price data, making it more sensitive to new information. In this article, you will learn how to calculate an exponential moving average step by step.
Step 1: Choose the Timeframe and Collect Data
First, decide the EMA’s timeframe which could range from a few minutes to weeks or months. Then, collect the asset’s closing prices for that period. Remember that EMA requires at least one period of price data for calculation.
Step 2: Calculate the Simple Moving Average
For the initial value of EMA, you must compute the SMA. Simply add up all closing prices within your chosen period and divide by the number of periods. This sets the initial benchmark for your EMA calculation.
Step 3: Determine the Smoothing Factor
Next, calculate the smoothing factor or weighting multiplier, which determines how much significance to assign recent price data. The formula for smoothing factor is:
α = 2 / (N + 1)
Where α is the smoothing factor and N represents your chosen number of periods.
Step 4: Calculate Your First Period’s EMA
With your initial SMA value available and smoothing factor calculated, compute your first period’s EMA using this formula:
EMA(t) = (C(t) x α) + [(EMAprev) x (1 – α)]
Where:
– EMA(t) represents the current period’s exponential moving average,
– C(t) is the closing price of your current period,
– α stands for your calculated smoothing factor, and
– EMAprev denotes previous period’s exponential moving average.
Step 5: Continue Your Calculations for Each Period
Repeat step 4 for each subsequent period in your chosen timeframe. Remember that as you move forward, use the EMA calculated during the previous period in place of EMAprev in the formula.
Conclusion:
Now you know how to calculate an exponential moving average for any financial asset of your choice. EMA is a valuable tool to identify trends and make informed trading decisions, but remember to combine it with other technical indicators and market knowledge to stay ahead in the game. Happy trading!
