Graph Style 4th Dimension RSI 戦略

価格変動とRSIレベルを組み合わせた戦略です。

テストでは年間平均約80%のリターンが示されています。ボラティリティの高い市場で優れたパフォーマンスを発揮します。

この戦略は、RSIの極値と直近の価格変動の方向を確認します。RSIが買われすぎ/売られすぎゾーンを離れ、直近の価格変動が動きを確認したときにポジションをオープンします。RSIが中央領域に戻るか、反対のシグナルが現れたときにポジションをクローズします。

詳細

  • エントリー条件: RSI極値を伴う価格変動方向。
  • ロング/ショート: 両方向。
  • エグジット条件: 反対のシグナルまたはRSIが中央に戻る。
  • ストップ: パーセントストップロス。
  • デフォルト値:
    • RsiPeriod = 14
    • OverboughtLevel = 70m
    • OversoldLevel = 30m
    • StopLossPercent = 1m
    • CandleType = TimeSpan.FromMinutes(5)
  • フィルター:
    • カテゴリ: モメンタム
    • 方向: 両方
    • インジケーター: RSI
    • ストップ: パーセント
    • 複雑さ: 基本
    • 時間軸: イントラデイ (5m)
    • 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
