Cette stratégie est un système de trading qui combine plusieurs moyennes mobiles simples (SMA) avec l'oscillateur stochastique. Elle exécute les transactions lorsque les tendances du marché sont clairement définies en établissant des zones de prix et des conditions d'identification des tendances.
La stratégie repose sur plusieurs éléments essentiels:
Cette stratégie construit un système de trading complet en combinant plusieurs indicateurs techniques, avec de fortes capacités de suivi des tendances et des mécanismes de gestion des risques. Bien qu'elle puisse faire face à des défis dans certaines conditions de marché, l'optimisation et le raffinement continus peuvent aider à maintenir une performance stable dans différents environnements de marché.
