分析機能 > インジケータ > Stochastic

Stochastic（ストキャスティクス）インジケータは、株価のターニングポイントの前兆となるモメンタムインジケータです。金融商品の終値を、一定期間の価格の範囲と比較します。ブルベアセットアップを特定することで将来の反転を予測するために使用できます。

ストキャスティクスインジケータは、K 線と D 線で測定されます。D 線をよく観察することで、FinancialChart から重要なシグナルを発見します。スローストキャスティクスを作成するには、SmoothingPeriod を 3 に設定します。SmoothingPeriod の値を 2 に設定すると、フルストキャスティクスが作成されます。ファストストキャスティクスを作成するには、SmoothingPeriod を整数値 1 に設定します。

FinancialChart にストキャスティクスインジケータを追加するには、FinancialChart 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。Stochastic  クラスは、KPeriod（整数値を受け取り、指定期間の価格範囲を計算する）、DPeriod（整数値を受け取り、K 線の移動平均を計算する）、SmoothingPeriod（整数値を受け取り、ファスト/フル/スローストキャスティクスを作成する）プロパティを公開します。これらのプロパティの値に基づいて、ストキャスティクスインジケータが計算され、FinancialChart にプロットされます。KLineStyle および DLineStyle プロパティを利用して、系列の外観を変更できます。

また、FinancialChart では、アプリケーションでアラートを作成したり、動的データの使用中にログを取るために、計算された D 値、Dx 値、K 値、Kx 値を実行時に取得できます。

Stochastic-Indicator

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、ボリュームチャートとは別にストキャスティクスインジケータをプロットします。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。
