FinancialChart for UWP
フィボナッチアーク
分析機能 > フィボナッチツール > フィボナッチアーク

フィボナッチアークは、FinancialChart 内の傾向線から広がる 3本の曲線とベースラインで構成されるテクニカル分析ツールです。これらのアークを使用して、トレーダーは、下降後のカウンタートレンドバウンドのレジスタンスゾーンまたはリバーサルゾーンを予想します。短期間の小さな株価変化に対しては、短いベースラインと幅が狭いアークが作成されます。長期間の大きな価格変化に対しては、長いベースラインと幅が広いアークが作成されます。

フィボナッチアークを作成するには、指定された期間の高（ピーク）と低（谷）の 2 点間にベースラインを描画します。このベースラインと主要なフィボナッチレベル 38.2%、50%、61.8% で交差するようにアークが描画されます。株価の変動だけが考慮されるフィボナッチリトレースメントとは異なり、フィボナッチアークでは時間要素も考慮されます。

FinancialChart で、フィボナッチアークを使用するには、コントロールをアプリケーションに追加し、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 プロパティを公開します。FibonacciArcs クラスのオブジェクトを作成すると、フィボナッチアークがチャートで有効になります。さらに、 FibonacciArcs クラスは、StartX、EndX、StartY、EndY の各プロパティを公開します。これらのプロパティに基づいて、FinancialChart にカーブがプロットされます。

Fibonacci-Arcs

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曲線をプロットします。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。

json ファイルの［ビルドアクション］プロパティが［埋め込まれたリソース］に設定されていることを確認します。
