ゴールドRSIダイバージェンス戦略

ゴールドRSIダイバージェンス戦略は、価格と相対力指数（RSI）の間の強気・弱気ダイバージェンスを識別することで、ゴールドをスキャルピングします。 価格が新しい安値を付けながらRSIがより高い安値を示すとき、戦略は買いを探します。 逆に、価格が新しい高値を付けながらRSIがより低い高値を示すとき、戦略は売ります。 両方のセットアップは、設定可能なバー範囲内に2つのピボットが発生した場合にのみ確認されます。

詳細

  • エントリー条件:
    • ロング: 価格が低い安値、RSIが高い安値、RSI < 40。
    • ショート: 価格が高い高値、RSIが低い高値、RSI > 60。
  • ロング/ショート: 両方。
  • エグジット条件:
    • ストップロスとテイクプロフィットを使用。
  • ストップ: pipsでの固定ストップロスとテイクプロフィット。
  • デフォルト値:
    • RsiLength = 60
    • StopLossPips = 11
    • TakeProfitPips = 33
  • フィルター:
    • カテゴリ: ダイバージェンス
    • 方向: 両方
    • インジケーター: RSI
    • ストップ: はい
    • 複雑さ: 中程度
    • 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: はい
    • リスクレベル: 中
