IGStandardDeviationIndicator Class Reference
|Inherits from||IGStrategyBasedIndicator : IGFinancialIndicator : IGFinancialSeries : IGSeries : NSObject|
The IGChartView™ control’s StandardDeviationIndicator is a financial indicator that statistically measures variation in stock prices or volatility. The difference between an individual security’s closing price and the average security closing price is called the dispersion. The larger the dispersion is the higher the standard deviation will be and therefore the volatility. The smaller the dispersion is (the difference between an individual closing price and the average price), the smaller the standard deviation and the lower the price volatility.
