LSMA-Winkel-Strategie

Diese Strategie verwendet den Winkel des Least Squares Moving Average (LSMA), um die Trendrichtung zu erkennen. Der Winkel wird durch die Differenz zwischen zwei LSMA-Werten angenähert, die durch eine konfigurierbare Anzahl von Balken getrennt sind.

  • Long-Einstieg: LSMA-Winkel steigt über den positiven Schwellenwert.
  • Long-Ausstieg: Winkel kehrt unter den positiven Schwellenwert zurück.
  • Short-Einstieg: LSMA-Winkel fällt unter den negativen Schwellenwert.
  • Short-Ausstieg: Winkel kehrt über den negativen Schwellenwert zurück.

Parameter

  • LSMA Period: Länge für die LSMA-Berechnung.
  • Angle Threshold: Absolutwert, der die neutrale Zone um Null definiert.
  • Start Shift: Älterer Balken für die Winkelberechnung.
  • End Shift: Neuerer Balken für die Winkelberechnung.
  • Candle Type: Kerzen-Datentyp für die Berechnung.

Hinweise

  • Winkelwerte werden je nach Wertpapier in Punkte skaliert (1000 für JPY-Paare, sonst 100000).
  • Funktioniert nur auf abgeschlossenen Kerzen.
