Keltner Stochastic 戦略

Keltnerチャネルとストキャスティクスオシレーターを組み合わせた戦略。 価格がKeltnerチャネルの境界に達し、Stochasticが売られすぎ/買われすぎの状態を確認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163%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。

このセットアップは、オシレーターがモメンタムの転換を確認する中、Keltnerバンド付近でのリバーサルをとらえることを目指しています。価格がエンベロープに押し当たるたびに、両方向でシグナルが発生する可能性があります。

素早いリバーサルを求める短期トレーダーに役立つかもしれません。リスクはATRベースのストップ距離によって抑制されます。

詳細

  • エントリー条件:
    • ロング: Close < LowerBand && StochK < StochOversold
    • ショート: Close > UpperBand && StochK > StochOverbought
  • ロング/ショート: 両方
  • エグジット条件:
    • ロング: Close > EMA
    • ショート: Close < EMA
  • ストップ: エントリーから StopLossAtr ATR
  • デフォルト値:
    • EmaPeriod = 20
    • AtrPeriod = 14
    • KeltnerMultiplier = 2.0m
    • StochPeriod = 14
    • StochK = 3
    • StochOversold = 20m
    • StochOverbought = 80m
    • StopLossAtr = 2.0m
    • CandleType = TimeSpan.FromMinutes(5).TimeFrame() チャネルはEMAの上下にKeltnerMultiplier倍のATRを加えたものです。ルール中のStochKは%Kで、StochPeriod本のストキャスティクスをStochK本で平滑化した値です。%Dはルールに関与しないため設定はありません。保有ポジションと逆方向のエントリーはドテンになります。ストップは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: Keltner Channel, Stochastic Oscillator
    • 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
