Bollinger Stochastic 戦略

Bollinger Stochastic は、ボリンジャーバンドとストキャスティクスオシレーターを組み合わせて、過度に伸び切った動きを識別します。 オシレーターが極端なゾーンにある状態で価格が外側のバンドに触れると、反発の可能性が示唆されます。

テストでは平均年間リターンは約133%を示しています。暗号資産市場で最も良いパフォーマンスを発揮します。

このシステムはそれらの極端な状況に逆張りし、ストキャスティクスが売られすぎの状態で価格が下側バンドに触れたときにロング、上側バンドでストキャスティクスが買われすぎの状態でショートします。

平均回帰が起こらない場合のリスクを、パーセントベースのストップで制限します。

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反対シグナル
  • 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
    • BollingerPeriod = 20
    • BollingerDeviation = 2
    • StochPeriod = 14
    • StochDPeriod = 3
    • StochOversold = 20
    • StochOverbought = 80 安値が下側バンドに触れ、ストキャスティクス%KがStochOversold未満なら買い、高値が上側バンドに触れ、%KがStochOverboughtを超えれば売ります。反対シグナルでドテンします。
  • 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, Stochastic
    • 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
