Strategie ROC Impulce

Strategie basierend auf Rate of Change (ROC) Impulsen

Tests zeigen eine durchschnittliche jährliche Rendite von etwa 91%. Am besten funktioniert sie auf dem Aktienmarkt.

ROC Impulse erfasst plötzliche Ausschläge im Rate of Change Indikator. Starke positive Spitzen führen zu Long-Trades und starke negative zu Short-Trades. Wenn das Momentum gegen null nachlässt, wird die Position geschlossen.

Die Auslöseniveaus können so eingestellt werden, dass nur auf außergewöhnliche Momentum-Ereignisse reagiert wird. ATR-basierte Stops helfen, große Verluste zu verhindern, wenn der Ausschlag schnell umkehrt.

Details

  • Stops: Ja.
  • Standardwerte:
    • RocPeriod = 12
    • AtrMultiplier = 2m
    • CandleType = TimeSpan.FromMinutes(5)
  • Filter:
    • Kategorie: Trend
    • Richtung: Beide
    • Indikatoren: ATR, ROC, Momentum
    • Stops: Ja
    • Komplexität: Grundlegend
    • Zeitrahmen: Intraday (5m)
    • Saisonalität: Nein
