La stratégie de quantification de la déviation du double axe RSI est une stratégie de trading avancée qui identifie les opportunités de reprise potentielles en détectant les déviations conventionnelles de hausse et de baisse entre le comportement des prix et l’indice relativement fort et faible ((RSI)). La stratégie utilise un algorithme de détection de pivot automatique, combinant deux méthodes de gestion de stop-loss/stop-loss différentes, pour établir automatiquement des positions lors de la confirmation d’un signal de déviation.
La stratégie de quantification de la déviation du double axe RSI offre une approche de trading inversée structurée grâce à une identification systématique de la déviation et à une gestion rigoureuse du risque. Sa valeur centrale réside dans la conversion des concepts traditionnels d’analyse technique en règles de trading quantifiables et dans l’adaptation aux différents environnements de marché grâce à un mécanisme de stop-loss bidirectionnel.
