J-Lines リボン 4サイクルエンジン戦略

J-Lines Ribbon 4-Cycle Engine戦略は、EMAのリボンとAverage Directional Indexを使用して市場をCHOP、LONG、SHORTサイクルに分類します。エントリーは新しいサイクルの検出とキーEMAからのリバウンドで発生し、エグジットは逆方向のクロスまたはスイングブレイクでトリガーされます。

詳細

  • エントリー条件:
    • ロング: 新しいLONGサイクル、またはEMA72がEMA89より上にある状態でEMA72/EMA126の上でリバウンド。
    • ショート: 新しいSHORTサイクル、またはEMA72がEMA89より下にある状態でEMA72/EMA126の下でリバウンド。
  • ストップ: 直近のスイング高値/安値。
  • デフォルト値:
    • DmiLength = 8
    • AdxFloor = 12
  • フィルター:
    • カテゴリ: トレンド
    • 方向: 両方
    • インジケーター: EMA, ADX
    • ストップ: はい
    • 複雑さ: 中程度
    • 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
