日中リバーサル戦略

日中リバーサルは、午前中のトレンドが消耗しがちな昼頃に生じる転換点を狙います。 セッション中盤は流動性が低下する傾向があり、トレーダーがポジションを手仕舞うことでリバーサルが起きます。

テストでは年平均リターンが約121%であることが示されています。仮想通貨市場で最も効果的です。

システムは昼頃のモメンタムの変化を監視し、午前の動きと逆方向にエントリーします。

パーセントストップでリスクを管理し、午後までにリバーサルが進展しない場合は決済します。

詳細

  • エントリー条件: インジケーターシグナル
  • 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逆シグナル
  • ストップ: はい、パーセントベース
  • デフォルト値:
    • CandleType = 15 minute
    • StopLossPercent = 2
    • MiddayHour = 12
    • AfternoonHour = 16 市場は24時間取引のため、セッションはUTCの1日とします。 朝の値動きは、当日の始値からMiddayHourに終わる足の終値までの変化です。MiddayHourからAfternoonHourの間に、その動きと逆に引けた最初の足で一度だけ逆張りし、AfternoonHourにポジションを閉じます。
  • フィルター:
    • カテゴリ: イントラデイ
    • 方向: 両方
    • インジケーター: Price Action
    • ストップ: はい
    • 複雑さ: 中級
    • 時間軸: イントラデイ
    • 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
