この戦略は,価格と封筒帯間のクロスオーバー状況を追跡することによって低値で低値で高値で販売する取引信号を生成するために,ナダラヤ-ワトソンカーネル回帰方法に基づく動的変動性エンベロープを構築する.数学的分析フレームワークを使用して,戦略は市場変化に適応することができます.
この戦略の核心は,価格のダイナミックエンベロープを計算することである.まず,カスタムバックウィンドウを使用して,価格のナダラヤ-ワトソンカーネル回帰曲線 (近,高,低) を構築し,平滑な価格推定を得ます.その後,カスタムATR長さのベースでATRを計算し,近距離因数で上下エンベロープ帯を形成します.価格が下からエンベロープに突入すると,購入信号が生成されます.価格が上からエンベロープを突破すると,販売信号が誘発されます.価格と波動性に関連する統計特性の間のダイナミックな関係を追跡することにより,戦略は自社の取引決定を適応的に調整します.
適切な最適化,十分なバックテスト,重要な要因の理解,そしてリアルタイムの取引における慎重なポジションサイズ化は,これらのリスクを軽減するのに役立ちます.
この戦略は,価格と変動の関係を動的に追跡することによって取引信号を生成するために,統計分析と技術指標分析を組み込む.パラメータは,市場状況と個人のニーズに基づいて調整することができる.全体的に言えば,堅固な理論的基盤にもかかわらず,実際のパフォーマンスは依然としてさらなる検証を必要としている.慎重に扱って慎重に取引する必要があります.
