Fibonacci Fans
Fibonacci Fans are the rising and falling trend lines based on the Fibonacci retracement points. These technical indicators help in measuring the speed of a trend’s movement, and also to construct support and resistance trend lines. The rising fan lines are used to predict support levels, while the falling fan lines can help predict resistance levels. In uptrend, if prices move below a Fibonacci Fan trend line, then they are expected to further fall until the next Fibonacci Fan trend line. In such cases, the Fibonacci Fan lines serve as support. Whereas, in a downtrend, if prices rise to a Fibonacci Fan trend line then that trend line is expected to serve as resistance.
To create Fibonacci Fans a trend line is first drawn through two points, the high and the low, in a given period and vertical distance between the two points is divided by the key Fibonacci ratios 38.2%, 50% and 61.8%. A point within the vertical distance is obtained as a result of each of these divisions. Three 'fan' lines are then created by drawing a line from the leftmost point to each of the three points representing a Fibonacci ratio. These are the trend lines that are based on Fibonacci retracement points.
To use Fibonacci Fans 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 FibonacciFans class enables Fibonacci fans in a chart. Additionally, the FibonacciFans class exposes StartX, EndX, StartY, and EndY properties. Based on the values of these properties, Fibonacci Fan lines are plotted on FinancialChart.
The following example considers stock data for a company Box Inc. over a period of time and plots fan lines 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:
