Stochastic Keltner 戦略

この戦略はStochastic Keltnerインジケーターを使用してシグナルを生成します。 Stoch %K < StochOversold かつ Price < Keltner lower band（下バンドで売られすぎ）の場合にロングエントリー。Stoch %K > StochOverbought かつ Price > Keltner upper band（上バンドで買われすぎ）の場合にショートエントリー。 混合市場で機会を求めるトレーダーに適しています。

テストでは年間平均リターン約61%を示しています。暗号資産市場で最もパフォーマンスが高いです。

詳細

  • エントリー条件:
    • ロング: Stoch %K < StochOversold && Price < Keltner lower band (oversold at lower band)
    • ショート: Stoch %K > StochOverbought && Price > Keltner upper band (overbought at upper band)
  • ロング/ショート: 両方。
  • エグジット条件:
    • ロング: 価格が中間バンドに戻ったときロングポジションを終了
    • ショート: 価格が中間バンドに戻ったときショートポジションを終了
  • ストップ: はい。
  • デフォルト値:
    • StochPeriod = 14
    • StochK = 3
    • StochOversold = 20
    • StochOverbought = 80
    • EmaPeriod = 20
    • KeltnerMultiplier = 2
    • AtrPeriod = 14
    • AtrMultiplier = 2 20と80はルールが示す%K水準の既定値です。バンドはEmaPeriod本のEMAにAtrPeriod本のATRのKeltnerMultiplier倍を加減したもので、中間バンドはEMAそのものです。ストップはエントリー時の終値から同じATRのAtrMultiplier倍離れた位置に置かれ、ローソク足の終値で確認されます。0で無効になります。 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シグナルはドテンになります。
    • CandleType = TimeSpan.FromMinutes(5)
  • フィルター:
    • カテゴリ: 混合
    • 方向: 両方
    • インジケーター: Stochastic Keltner
    • 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
