Stochastic
Stochastic indicator is a momentum indicator used to foreshadow price turning points. It compares the closing price of a financial instrument with its range of prices over a period of time. It can be used to anticipate future reversals by identifying bull and bear set-ups. FinancialChart helps in technical analysis by creating stochastic indicator oscillator for a given data.
Stochastic Oscillator indicator is measured with K line and D line. The D line is followed closely to indicate any major signals in the FinancialChart. To create a slow stochastic oscillator, SmoothingPeriod is set to 3, while a SmoothingPeriod value of 2 creates full stochastic oscillator. To create a fast stochastic oscillator, the SmoothingPeriod is set to an integer value of 1.
To use stochastic indicator in FinancialChart, add a FinancialChart control to your application and bind it to an appropriate data source. ItemsSource object enables data binding or populating data in FinancialChart. The Stochastic class exposes KPeriod (takes integer value to calculate price range over the specified period), DPeriod (takes integer value to calculate the Moving Average of K line), and Smoothing period (takes integer value to create fast, full or slow oscillator) properties. Based on the values of these properties, FinancialChart calculates and plots the data points for Stochastic indicator. KLineStyle and DLineStyle properties can be utilized to change the appearance of series.
FinancialChart also enables users to fetch the calculated D values, Dx values, K values, and Kx values in the run time, for the purpose of creating alerts in application or maintaining logs while working with dynamic data.
The following example considers stock data for a company Box Inc. over a period of time and plots its Stochastic Oscillator Indicator apart from the volume chart, as shown in the image above. The example uses data from a json file, and DataService.cs class is created to access this json file.
Make sure that Build Action property of the json file is set to Embedded Resource.
