La stratégie est un système de suivi de la tendance combinant des moyennes mobiles multi-périodes et une analyse du volume des transactions. La stratégie confirme la tendance globale à l’aide des trois moyennes EMA9, WMA20 et WMA200 des cycles de la ligne solaire, tout en introduisant l’indicateur OBV (On Balance Volume) et son EMA pour la confirmation du volume des transactions, permettant des transactions de suivi de tendance plus robustes.
La stratégie est basée sur deux conditions fondamentales:
La stratégie, combinant l’analyse de tendances à plusieurs cycles et la confirmation des volumes de transactions, construit un système de suivi des tendances relativement complet. La logique de la stratégie est claire, le contrôle des risques est raisonnable, mais il reste de la place pour l’optimisation. Il est recommandé aux traders de tester soigneusement dans le marché réel et d’ajuster les paramètres en fonction des caractéristiques spécifiques du marché.
