Fibonacci Arcs
Fibonacci Arcs are the technical analysis tools composed of a Base Line and three curved lines extending out from a trend line on FinancialChart. These arcs enable traders to predict resistance or reversal zones for counter trend bounce situations after decline. A small change in price over a short time period produces narrow arcs with a short Base Line; a big price move over a long time period produces wide arcs with a long Base Line.
To create Fibonacci Arcs a Base Line is drawn through two points, the high (peak) and the low (trough), in a given period. Arcs are drawn intersecting this base line at key Fibonacci levels 38.2%, 50%, and 61.8%. In contrast with Fibonacci Retracements, which are concerned only with change in price, Fibonacci Arcs consider time element too.
To use Fibonacci Arcs 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 property. Creating object of FibonacciArcs class enables fibonacci arcs in a chart. Additionally, the FibonacciExtension class exposes StartX, EndX, StartY, and EndY properties. Based on the values of these properties, curves are plotted on FinancialChart.
The following example considers stock data for a company Box Inc. over a period of time and plots curves 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.
Make sure to add the following references in DataService.cs:
