この戦略は,ドルコスト平均 (DCA) とボリンジャーバンド技術指標を組み合わせたインテリジェントな投資アプローチである. 平均逆転原理を活用することで,価格の引き下げ中に体系的にポジションを構築する. 価格がボリンジャーバンドの下位を突破したとき,市場の訂正中により良いエントリー価格を達成することを目的とした,コアメカニズムは固定金額の購入を実行する.
この戦略は3つの基本的な柱の上に構築されている: 1) 定期的な固定金額投資を通じてタイミングリスクを軽減するドルコスト平均化; 2) 価格が最終的に歴史的な平均に戻ると仮定する平均逆転理論; 3) 過買い・過売区間を特定するためのボリンジャー帯指標. 価格が下帯を下回ると購入信号が起動し,購入量は設定された投資額を現在の価格で割ることで決定される. 戦略は,上位および下位帯を定義するために標準偏差倍数2の中間帯として200期EMAを使用する.
これは技術分析と体系的な投資方法を組み合わせた堅牢な戦略である.リスクを減らすためにドルコスト平均を導入しながら,過剰販売の機会を特定するためにボリンジャーバンドを使用する.成功の鍵は適切なパラメータ設定と厳格な実行規律にある.リスクが存在する一方で,継続的な最適化とリスク管理は戦略の安定性を向上させることができる.
