Weighted Moving Average Formula
The weighted moving average formula is a moving average of data that gives more weight to the more recent data in the period and less weight to the older data in the period. This formula smoothes a data series. This makes analyzing volatile data easier.
Formula Details
Syntax

FinancialFormula.WeightedMovingAverage,
"Period",
"Price",
"WMA")
Parameters
This formula takes one required parameter.
- Period
Period for calculating the weighted moving average.
Input Values
This formula takes one input Y value.
- Price
Price for which the weighted moving average is calculated.
Output Value
This formula outputs two Y values.
- WMA
Weighted moving average.
Remarks
The Line chart type is a convenient chart type to display the formula output.
Example
The following example takes input from Series1's second Y value (Series1:Y2) and outputs a 20-day weighted moving average on Series2's first Y value (Series2:Y).
Chart1.DataManipulator.FinancialFormula (FinancialFormula.WeightedMovingAverage, "20", "Series1:Y2", "Series2:Y")
Chart1.DataManipulator.FinancialFormula (FinancialFormula.WeightedMovingAverage, "20", "Series1:Y2", "Series2:Y");
