ダイナミック・ティックス・オシレーター・モデル (DTOM)

Dynamic Ticks Oscillator Model は NYSE Down Ticks 指数の変化率を使用します。ROC が標準偏差に基づくダイナミック閾値を下回ったとき、戦略はロングポジションを建てます。ROC が正の閾値を上回ったときにポジションを閉じます。

詳細

  • エントリー条件: ROC < -StdDev * EntryStdDevMultiplier
  • ロング/ショート: ロングのみ。
  • エグジット条件: ROC > StdDev * ExitStdDevMultiplier
  • ストップ: いいえ。
  • デフォルト値:
    • RocLength = 5
    • VolatilityLookback = 24
    • EntryStdDevMultiplier = 1.6m
    • ExitStdDevMultiplier = 1.4m
    • CandleType = TimeSpan.FromMinutes(5).TimeFrame()
  • フィルター:
    • カテゴリ: 平均回帰
    • 方向: ロングのみ
    • インジケーター: RateOfChange, StandardDeviation
    • ストップ: いいえ
    • 複雑さ: 初心者
    • 時間軸: 日足
    • 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
