Standard deviation is calculated using the closing price over the past 5-periods. To calculate standard deviation:
- Step 1: Average = Calculate the average closing price over the past 5-days.
- Step 2: Difference = Calculate the variance from the Average for each Price.
- Step 3: Square the variance of each data point.
- Step 4: Sum of the squared variance value.
- Step 5: For Standard Deviation 2 multiple the result by 2. For Standard Deviation 3 multiple the result by 3.
- Step 6: Divide the result by the number of data points in the series less 1.
- Step 7: The final result is the Square root of the result of Step 6.
