Vwap Stochastic 戦略

VWAPとストキャスティクスインジケーターを組み合わせた戦略。価格がVWAPを下回り、Stochasticが売られすぎのときに買い。価格がVWAPを上回り、Stochasticが買われすぎのときに売り。

テストでは年平均リターン約187%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。

VWAPは平均取引レベルを示し、Stochasticは買われすぎまたは売られすぎの状態を示します。ロングはVWAP下方で上昇するオシレーターとともに発動し、ショートはVWAP上方で下降するオシレーターとともに発動します。

イントラデイの価値水準を観察するデイトレーダーはこのスタイルから恩恵を受けることができます。ストップはエントリー価格から一定割合の位置に設定されます。

詳細

  • エントリー条件:
    • ロング: Close < VWAP && StochK < OversoldLevel
    • ショート: Close > VWAP && StochK > OverboughtLevel
  • ロング/ショート: 両方
  • エグジット条件:
    • ロング: Close > VWAP
    • ショート: Close < VWAP
  • ストップ: StopLossPercent を使用したパーセントベース
  • デフォルト値:
    • StochPeriod = 14
    • StochKPeriod = 3
    • OverboughtLevel = 80m
    • OversoldLevel = 20m
    • StopLossPercent = 2m
    • CandleType = TimeSpan.FromMinutes(5).TimeFrame() 市場は24時間取引のため、セッションVWAPはUTCの毎日リセットされ、各足の典型価格を出来高で加重します。ルール中のStochKは%Kで、StochPeriod本のストキャスティクスをStochKPeriod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。
  • フィルター:
    • カテゴリ: 平均回帰
    • 方向: 両方
    • インジケーター: VWAP, 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
