The exponential moving average is used to create indicators like moving average convergence and divergence and percentage price oscillator. The exponential moving average is used to calculate the value one the next day by providing the weightage to the most recent days, thus eliminating the drawback faced in the simple moving average.ĮMAt = + EMAy × Value for 31st day = īut SMA has certain drawbacks that it doesn’t consider the weightage of the most recent data i.e., all data points are given the same amount of weightage, which may lead to a huge difference in the predicted value and the actual value to overcome this problem we use the Exponential method. The formula used here for calculating the moving average isįor example, we have the data of the last 30 days of the closing price, and we need to determine the price for the next day then we can take the sum of the 30 days value of the closing price and divide it by 30 to get the prediction of the next day. In this method, we calculate the simple arithmetic mean of the values of a certain period to predict the value for the next period. In order to eliminate the short term trends effect, we use this method. In the short term, the prices of the stock may fluctuate a lot, which may cause the graph to look spiky, and this can hardly result in decision making. The longer the lag (time is taken), the smoother the MA will be.Ī moving average (MA) can be used as a technical indicator to represent the prices of shares and stocks by eliminating or smoothening the short term effect on the stock price. It shows the average prices over the past 20 days for each price point on the chart. The chart shows a 20-days SMAs of an imaginary share. While SMA gives equal weightage to all the past days’ prices in the period taken for averaging, EMA gives more weightage to more recent prices. The other is the exponential moving average (EMA). The most common moving average in use is the simple moving average or SMA, which takes the simple average of past prices for a given period. Moving average or MA is an indicator in technical analysis, which smoothes out the spiked chart of share prices to reveal underlying trends by plotting the average of past share prices over a specific period of time. They are Simple Moving Average and Exponential Moving Average.
There are two types of moving average.A moving average (MA) can be used as a technical indicator to represent the prices of shares and stocks by eliminating or smoothening the short term effect on the stock price.
