Fibonacci Retracements

In This Topic

Fibonacci Retracements are the technical analysis tools comprising of horizontal lines (or retracement levels) in a FinancialChart. These levels are used to identify the areas of support (stock prices won’t go lower) or resistance (stock prices won’t go higher) before the trend continues in original direction. These Fibonacci levels are created by first drawing a trend line between the high and low (two extremes), and then dividing the vertical distance by the key Fibonacci ratios of 23.6%, 38.2%, 50%, 61.8% and 100%. A vital Fibonacci retracement level is 61.8%, the maximum pullback zone, showing clear buy or sell signals.

To use Fibonacci Retracement tool in FinancialChart, add the control to your application, and bind it to an appropriate data source or populate data in it through Quote Collection. ItemsSource object enables data binding or populating data in FinancialChart. Fibonacci class exposes Uptrend and Levels properties. Based on the values you set for these properties, alert levels are plotted on FinancialChart.

The following example considers stock data for a company Box Inc. over a period of time and plots alert levels (retracements) on the same financial 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.
