MA mit logistischer Funktion

MA mit logistischer Funktion ist eine Strategie auf Basis gleitender Durchschnitte, die einen schnellen und einen langsamen gleitenden Durchschnitt für Einstiege verwendet und prozentuale oder logistikbasierte Ausstiege unterstützt.

Details

  • Daten: Preiskerzen.
  • Einstiegskriterien:
    • Long: Schlusskurs > schnelle MA und schnelle MA > langsame MA.
    • Short: Schlusskurs < schnelle MA und schnelle MA < langsame MA.
  • Ausstiegskriterien: Prozentziele oder logistische Wahrscheinlichkeitsschwellen.
  • Stops: Prozentuale oder logistik-wahrscheinlichkeitsbasierte Ausstiege.
  • Standardwerte:
    • FastLength = 9
    • SlowLength = 21
    • MaType = MaTypeEnum.EMA
    • ExitType = ExitTypeEnum.Percent
    • TakeProfitPercent = 20
    • StopLossPercent = 5
    • LogisticSlope = 10
    • LogisticMidpoint = 0
    • TakeProfitProbability = 0.8
    • StopLossProbability = 0.2
  • Filter:
    • Kategorie: Trendfolge
    • Richtung: Long & Short
    • Indikatoren: MA
    • Komplexität: Niedrig
    • Risikolevel: Mittel
