SRブレークアウト戦略は,LonesomeTheBlue
SRブレイクアウト戦略は,サポートとレジスタンスブレイクアウトという古典的な考えに基づいた取引戦略である.ピボットハイとピボットロー関数を用いてサポートとレジスタンスレベルを計算し,閉じる価格がこれらのレベルを突破して取引信号を生成するかどうかを判断することによって.この戦略の利点は,アイデアが明確で,実装し最適化するのが簡単である.同時に,不安定な市場でパフォーマンスが悪いことや,固定ストップ損失と利益率によって引き起こされるリスクなどのリスクもあります.将来,この戦略の技術指標,ストップ損失と利益,フィルタリング条件,サポートと抵抗最適化などの側面から最適化および改善することを検討し,安定性と収益性を向上させることができます.
