The coefficient of variation (CoefficientOfVariation) (CoV), also known as relative standard deviation (RSD), is a standardized measure of dispersion of a probability distribution or frequency distribution. It is defined as the ratio of the standard deviation to the mean. When used in the stock market, it helps to determine the amount of volatility in comparison to the expected return rate of investment.

Implementation and Usage

To initialize Coefficient Of Variation indicator, use one of the following constructors:

CoefficientOfVariation – set default values: period = 14

CoefficientOfVariation(Int32) – set value for period

CoefficientOfVariation(TimeSpan) – sets time period

Use

CoV - property to get current value

Example

Copy

 1// Create new instance
 2var indicator = new CoefficientOfVariation(28);
 3
 4// Number of stored values
 5indicator.HistoryCapacity = 2;
 6
 7// Add new data point
 8indicator.Add(CurrentPrice);
 9
10// Get indicator value
11double IndicatorValue = indicator.CoV;
12// Get previous value
13if (indicator.HistoryCount == 2)
14{
15    double IndicatorPrevValue = indicator[1];
16}
