Bollinger Volume 戦略

出来高確認を伴うボリンジャーバンドのブレイクアウトを利用する戦略。 出来高が増加した状態でボリンジャーバンドを上/下に価格がブレイクしたときにポジションを取ります。

テストでは年平均リターン約178%を示しています。株式市場で最もパフォーマンスが高いです。

ボリンジャーバンドはボラティリティの拡大を示し、出来高がブレイクアウトを確認します。強い活動を伴ってバンドの外側でポジションが取られます。

継続を期待するブレイクアウトトレーダーに適しています。ATRベースのストップで損失を管理可能に保ちます。

詳細

  • エントリー条件:
    • ロング: Close > UpperBand && Volume > AvgVolume * VolumeMultiplier
    • ショート: Close < LowerBand && Volume > AvgVolume * VolumeMultiplier
  • ロング/ショート: 両方
  • エグジット条件:
    • 価格が中央バンドに戻る
  • ストップ: StopLossAtr を使用したATRベース
  • デフォルト値:
    • BollingerPeriod = 20
    • BollingerDeviation = 2.0m
    • VolumePeriod = 20
    • VolumeMultiplier = 1.5m
    • StopLossAtr = 2.0m
    • AtrPeriod = 14
    • CandleType = TimeSpan.FromMinutes(5).TimeFrame() AvgVolumeは直前VolumePeriod本の平均出来高です。保有ポジションと逆方向のエントリーシグナルはドテンになります。ストップはエントリー時の終値からStopLossAtr倍のATRの位置にあり、足の終値で判定します。
  • フィルター:
    • カテゴリ: 平均回帰
    • 方向: 両方
    • インジケーター: Bollinger Bands, Volume
    • ストップ: はい
    • 複雑さ: 中級
    • 時間軸: 中期
    • 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
