ボリンジャーバンドリバーサル戦略
ボリンジャーバンドの外側での価格の極端な値は、多くの場合中央バンドに向かって戻ります。このアプローチはその拡張に逆らい、ロウソクが緑で引けると下限バンドを下回る急落で買い、赤いロウソクの後に上限バンドを上回る反発で売ります。
テストでは年平均リターン約94%を示しています。株式市場で最もよく機能します。
アルゴリズムは各バーでボリンジャーバンドを計算し、引け値が外側のバンドを突破するかどうかを確認します。強気ロウソクが下限バンドの下で引けるとロングが開かれ、弱気ロウソクが上限バンドの上で引けるとショートが取られます。ストップはATRの倍数に基づき、価格が中央バンドに戻るとエグジットが発生します。
平均回帰トレードは通常わずか数バーしか続かないため、このセットアップは短期のボラティリティ収縮に適しています。
詳細
- エントリー条件: 強気ロウソクで下限バンドを下回る引けか、弱気ロウソクで上限バンドを上回る引け。
- ロング/ショート: 両方。
- エグジット条件: 価格が中央バンドを越えるかストップロス。
- ストップ: はい、ATRベース。
- デフォルト値:
BollingerPeriod= 20BollingerDeviation= 2.0AtrMultiplier= 2.0CandleType= 5 minute
- 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, ATR
- ストップ: はい
- 複雑さ: 基本
- 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
