MA Cross + DMI-Strategie

Handelt eine Kreuzung von schnellen und langsamen exponentiellen gleitenden Durchschnitten nur dann, wenn der Directional Movement Index die Trendstärke bestätigt. Indem auf das Dominieren von +DI oder -DI gewartet wird, während der ADX über einem Schlüsselniveau steigt, filtert das System schwache Kreuzungen heraus.

Diese Strategie kann Long- oder Short-Positionen eingehen und steigt bei entgegengesetzten Kreuzungen aus. Die ADX-Filterung hilft der Methode, Seitwärtsphasen zu vermeiden, in denen gleitende Durchschnitte häufig Fehlsignale erzeugen.

Details

  • Einstiegskriterien:
    • Long: Schnelle EMA kreuzt über die langsame EMA, +DI > -DI und ADX über dem Schlüsselniveau.
    • Short: Schnelle EMA kreuzt unter die langsame EMA, -DI > +DI und ADX über dem Schlüsselniveau.
  • Ausstiegskriterien:
    • Entgegengesetzte Kreuzung oder manueller Stop.
  • Indikatoren:
    • Zwei EMAs (Perioden 10 und 20)
    • Directional Movement Index (Länge 14, ADX-Glättung 14)
  • Stops: Standardmäßig keine; StartProtection kann verwendet werden.
  • Standardwerte:
    • Ma1Length = 10
    • Ma2Length = 20
    • DmiLength = 14
    • AdxSmoothing = 14
    • KeyLevel = 20
  • Filter:
    • Trendfolge
    • Funktioniert auf Intraday- bis Swing-Zeitrahmen
    • Indikatoren: EMA, DMI
    • Stops: Optional
    • Komplexität: Grundlegend
