フィボナッチリトレースメントは、FinancialChart 内の何本かの水平線(リトレースメントレベル)で構成されるテクニカル分析ツールです。これらのレベルは、トレンドが元の方向で継続するまでのサポート(株価が下がらない)またはレジスタンス(株価が上がらない)の幅を明示するために使用されます。これらのフィボナッチレベルは、最初に高低(両極値)間の傾向線を描画し、次のそれらの垂直距離を主要なフィボナッチ比率 23.6%、38.2%、50%、61.8%、100% で分割することによって作成されます。重要なフィボナッチリトレースメントレベルは、最大プルバックゾーンの 61.8% で、明確な買いまたは売りシグナルを示します。
FinancialChart でフィボナッチリトレースメントを使用するには、コントロールに適切なデータソースを連結するか、Quote Collection でコントロールにデータを追加します。FinancialChart にデータを連結または追加するには、ItemsSource オブジェクトを使用します。
Fibonacci クラスは、Uptrend および Levels プロパティを公開します。これらのプロパティで設定した値に基づいて、FinancialChart に警告レベルがプロットされます。次の例は、上の図で示すように、企業 Box Inc. の一定期間の株価を考察し、同じ株価チャートに警告レベル(リトレースメント)をプロットします。この例では、json ファイルのデータを使用します。この json ファイルにアクセスするために、DataService.cs クラスを作成します。
