Cette stratégie combine plusieurs moyennes mobiles pour mettre en œuvre une stratégie de suivi de tendance simple.
La fonction smoothMA appelle d'abord la fonction variante, qui peut générer divers types de moyennes mobiles comme SMA, EMA, DEMA, etc. Après que la fonction variante ait généré la moyenne mobile spécifiée, smoothMA appelle de manière récursive la variante plusieurs fois pour superposer la smoothing. Cela donne lieu à une moyenne mobile avec un haut niveau de fluidité.
Envisagez de combiner d'autres indicateurs tels que MACD, KDJ pour améliorer la précision du signal. Optimisez les paramètres MA pour réduire le décalage. Utilisez un stop loss raisonnable pour contrôler la perte d'une seule transaction. Contrôlez également la fréquence des transactions pour minimiser les coûts de transaction.
La stratégie suit les tendances via plusieurs superpositions de moyennes mobiles, filtrant efficacement le bruit du marché. Les avantages sont la simplicité et la flexibilité.
