この戦略は,Nadaraya-Watson核帰帰法に基づいて,動的波動率の包囲帯を構成し,価格と包囲帯の交差状況を追跡することによって,低価格で高価格で売る取引信号を実現する.この戦略は,数学分析の基礎を持ち,市場変化に自律的に適応する.
戦略の核心は,価格の動的包囲帯を計算することです. まず,カスタマイズされた回顧期に基づいて価格 ((閉店価格,最高価格,最低価格) のナダラヤ-ワトソン核回帰曲線を構成し,平らな価格見積もりを得ます. その後,カスタマイズされたATR長さのベースでATR指標を計算し,近端因子と遠端因子を組み合わせて,上下包囲帯の範囲を得ます.
これらのリスクは,主にパラメータの最適化,反省,影響要因の理解,慎重な実盤によって回避および軽減されます.
この戦略は,統計分析と技術指標分析を統合し,価格と変動率を動的に追跡することによって,低価格と高価格の取引シグナルを実現する.市場と自身の状況に応じてパラメータを調整することができる.全体的に,戦略の理論的基盤は堅牢であり,実際のパフォーマンスはさらに検証される必要がある.慎重に観察し,慎重に実態を観察する必要があります.
