Le RSI utilise les valeurs de l’EMA à court terme (6 et 8 et 12 jours), à moyen terme (55 jours) et à long terme (150 et 200 et 250 jours) pour analyser la direction et la force des tendances du marché. Le RSI utilise les seuils configurables d’achat (30) et de vente (70) pour évaluer la dynamique et identifier les situations de surachat ou de survente. La stratégie utilise également un mécanisme de sortie unique, qui est déclenché lorsque le cours de clôture touche la plage de décalage configurable de l’EMA du 12e jour (sous-entendu 0.5), offrant ainsi une méthode de protection potentielle des gains ou de réduction des pertes.
Cette stratégie analyse le marché à partir de deux dimensions de la tendance et de la dynamique, tout en utilisant un mécanisme unique de sortie standard pour capturer les opportunités de tendance tout en maîtrisant les risques. L’idée de la stratégie est claire, la logique est rigoureuse, le code est simple et efficace.
