Die Dual EMA Crossover Strategie ist eine häufig verwendete Trend-Folge-Strategie. Sie verwendet zwei EMA-Linien mit unterschiedlichen Perioden und erzeugt Kaufsignale, wenn die kürzere Periode EMA über die längere Periode EMA kreuzt und Verkaufssignale, wenn das Gegenteil geschieht, um Trendänderungen zu erfassen.
Die Kernlogik dieser Strategie basiert auf den
Insbesondere verwendet diese Strategie die Parameter length1 und length2, um die Perioden von zwei EMA-Linien festzulegen. demaVal1 ist die length1 Periode EMA und demaVal2 ist die length2 Periode EMA. Sie werden berechnet wie folgt:
demaVal1 = EMA(close, length1)
demaVal2 = EMA(close, length2)
Wenn demaVal1 den demaVal2 überschreitet, wird das Kaufsignal demaCrossover generiert. Wenn das Gegenteil geschieht, wird das Verkaufssignal demaCrossunder generiert. Die Strategie sendet Handelsaufträge auf der Grundlage dieser beiden Signale.
Zu den Vorteilen dieser Strategie gehören:
Diese Strategie birgt auch einige Risiken:
Auf der Grundlage der oben genannten Risiken könnten folgende Aspekte optimiert werden:
Zusammenfassend ist die Dual EMA Crossover Strategy ein einfaches, aber praktisches Trendfolgensystem. Durch die Erbschaft der ausgereiften Theorien der EMA-Analyse und mit angemessener Parameter-Tuning und Verbesserung der Filterbedingungen kann sie auf den Trendhandel in verschiedenen Instrumenten mit guten Anwendungsperspektiven angewendet werden.
