Die Strategie verwendet eine Kombination aus Brin-Bands und Triple Overtrend-Indikatoren. Die Brin-Bands dienen zur Identifizierung von extremen Preisschwankungen, während die Triple Overtrends eine mehrfache Bestätigung der Trendrichtung durch verschiedene Parameter-Einstellungen bieten. Der Handel erfolgt nur, wenn alle Signale übereinstimmen, um das Risiko von falschen Signalen zu verringern.
Die Kernlogik der Strategie umfasst die folgenden Schlüsselelemente:
Dies ist eine Trend-Tracking-Strategie, die Brin-Bands und Triple Overtrends kombiniert, um die Zuverlässigkeit des Handels durch die Bestätigung mehrerer technischer Indikatoren zu verbessern. Die Strategie hat eine starke Trendfangfähigkeit und Risikokontrolle, muss aber auch auf die Auswirkungen des Marktumfelds auf die Strategie-Performance achten. Durch kontinuierliche Optimierung und Verbesserung wird die Strategie unter verschiedenen Marktbedingungen stabil bleiben.
