MAVA Xonax-Strategie

Diese Strategie verwendet exponentielle gleitende Durchschnitte von Eröffnungs- und Schlusskursen, um Richtungsänderungen zu erkennen. Stop-Loss- und Take-Profit-Abstände werden aus den Hoch- und Tief-EMAs abgeleitet, sodass Trades vordefinierte Risiko- und Ertragsniveaus haben.

Details

  • Einstiegskriterien:
    • Long: EMA der Eröffnung kreuzt EMA des Schlusses von unten, basierend auf den letzten zwei abgeschlossenen Kerzen.
    • Short: EMA der Eröffnung kreuzt EMA des Schlusses von oben, basierend auf den letzten zwei abgeschlossenen Kerzen.
  • Long/Short: Beide
  • Stops: Fester Stop-Loss und Take-Profit basierend auf EMA-Bereichen.
  • Standardwerte:
    • EmaPeriod = 6
    • CandleType = TimeSpan.FromMinutes(240).TimeFrame()
  • Filter:
    • Kategorie: Umkehr
    • Richtung: Beide
    • Indikatoren: EMA
    • Stops: Ja
    • Komplexität: Grundlegend
    • Zeitrahmen: Langfristig
    • Saisonalität: Nein
    • Neuronale Netze: Nein
    • Divergenz: Nein
    • Risikolevel: Mittel
