IU レンジ超え戦略

ローソク足の実体が直近のローソク足の前回レンジより大きいときにトレードを開くブレイクアウト戦略。

このシステムは現在のローソク足の実体を、設定可能なルックバック期間内の最高・最低の始値/終値間のレンジと比較します。実体が前回のレンジを超えた場合、ローソク足の方向にエントリーし、設定可能なストップ手法でリスクを管理します。

詳細

  • エントリー条件: ローソク足の実体が前回レンジより大きい；方向はローソク足の実体による。
  • ロング/ショート: 両方。
  • エグジット条件: ストップロスまたはテイクプロフィット。
  • ストップ: 前のローソク足、ATR、またはスイングレベル。
  • デフォルト値:
    • LookbackPeriod = 22
    • RiskToReward = 3
    • StopLossMethod = PreviousHighLow
    • AtrLength = 14
    • AtrFactor = 2m
    • SwingLength = 10
    • CandleType = TimeSpan.FromMinutes(1)
  • 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: Highest, Lowest, ATR
    • ストップ: はい
    • 複雑さ: 中
    • 時間軸: 任意
    • 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
