この戦略は,ブリン帯とATR指標をベースにしたインテリジェントな取引システムで,多層のストップ・ロスの仕組みを組み合わせている.戦略は,主にブリン帯下線近くの反転信号を識別して多頭入場を行い,ダイナミック・ストップ・ロスを採用してリスクを管理している.システムは,20%の利益目標と12%のストップ・ロスを設計し,ATR指標と組み合わせてダイナミック・ストップ・ロスを実現し,利益を保護しながら,トレンドに十分な発展の余地を与えることができる.
戦略の中核となるロジックには、次の主要な部分が含まれます。
この戦略は,ブリン帯とATR指標を介して,多層の取引システムを構築し,入場,止損,利益の結末などにおいてダイナミックな管理方法を採用している.戦略の優位性は,その完善したリスク制御システムと市場の波動に対する自己適応能力にある.提案された最適化方向によって,戦略には,大きな向上の余地がある.特に,より大きな時間周期で使用するのに適し,質の高い資産を持つ投資家にとって,ポジションの構築と減仓のタイミングを最適化するのに役立つ.
