この戦略の核心思想は,市場底部を正確に把握するために,Vix Fix指標とその線形回帰を組み合わせることです.この戦略は"Fix Regression Bottom Fishing Strategy"と呼ばれています.
上記のプロセスは,Vix Fix信号の正確性とタイミングを向上させ,いくつかの偽信号をフィルタリングし,したがって底部を正確に捕捉するために線形回帰を使用します.
この戦略は,シグナル品質を改善するために線形回帰を導入しながら,ボトムを判断するためにVix Fixインジケーターを使用し,それによって効果的に市場のボトムを捕獲する.この戦略はシンプルで,実践的で,立派な結果を生む.主なリスクは完全にフィルタリングできない偽信号にあります.我々はまだパラメータ設定を最適化し,戦略をより堅牢にするために信号をさらに確認するための他の手段を導入することを検討する必要があります.全体として,この戦略は市場のボトムを決定する新しい効果的な方法を提供し,さらなる研究に価値がある.
