Color HMA Umkehr-Strategie

Strategie basierend auf Steigungsänderungen des Hull Moving Average. Sie schließt Positionen gegen die neue Richtung und eröffnet Positionen im Trend, wenn der HMA umkehrt.

Parameter

  • HmaPeriod — Periode für den Hull Moving Average.
  • CandleType — Art der zu verwendenden Kerzen.
  • BuyOpen, SellOpen — Eröffnung von Long-/Short-Positionen erlauben.
  • BuyClose, SellClose — Schließen von Long-/Short-Positionen erlauben.

Signale

  • Aufwärtsumkehr: Vorheriger HMA fiel und aktueller Wert steigt → Shorts schließen und Long eröffnen.
  • Abwärtsumkehr: Vorheriger HMA stieg und aktueller Wert fällt → Longs schließen und Short eröffnen.

Die Strategie verwendet Market-Orders und handelt mit dem in Strategy.Volume angegebenen Volumen.
