Nデイ・ブレイクアウト

NデイのN日高値/安値ブレイクアウト戦略。Nデイ・ブレイクアウトは、指定された期間における新しい高値または安値を探します。モメンタムを予測しながら、価格が直近のN日高値または安値を突破した時にエントリーが発生します。移動平均フィルターとパーセンテージストップがエグジットを管理します。

テスト結果では、年間平均リターンが約43%であることが示されています。株式市場で最も効果を発揮します。

前回の極値のブレイクを待つことで、システムは方向性のある動きの開始を捉えようとします。トレンドフォロー型の移動平均でフィルタリングすることで、保ち合い中に発生するダマシシグナルを回避するのに役立ちます。

詳細

  • エントリー条件: MAに基づくシグナル。
  • ロング/ショート: 両方の方向。
  • エグジット条件: 逆シグナルまたはストップ。
  • ストップ: はい。
  • デフォルト値:
    • LookbackPeriod = 20
    • MaPeriod = 20
    • StopLossPercent = 2.0m
    • CandleType = TimeSpan.FromHours(1) 付属の履歴データは1か月分のため、20本のウォームアップ後に残る日足は約10本で、日足では2024年3月のBTCで注文が1件も発生しません。そのため既定値は同じ期間の1時間足を使い、日足は設定で指定できます。
  • フィルター:
    • カテゴリ: ブレイクアウト
    • 方向: 両方
    • インジケーター: MA
    • ストップ: はい
    • 複雑さ: 基本
    • 時間軸: 日足
    • 季節性: いいえ
    • ニューラルネットワーク: いいえ
    • ダイバージェンス: いいえ
    • リスクレベル: 中
