Cette stratégie est un système de trading quantitatif basé sur l'indice de force d'Elder (EFI), combinant les déviations standard et les moyennes mobiles pour la génération de signaux, tout en utilisant l'ATR pour le positionnement dynamique des stop-loss et des take-profit.
La stratégie repose sur plusieurs éléments essentiels:
La stratégie construit un système de négociation complet en combinant les indicateurs EFI, l'écart type et l'ATR. Ses atouts résident dans une fiabilité élevée du signal et un contrôle raisonnable des risques, bien que l'optimisation pour différents environnements de marché soit encore nécessaire. La stabilité et la rentabilité de la stratégie peuvent être encore améliorées en ajoutant une évaluation des conditions du marché, un filtrage du volume et d'autres mécanismes.
