Introduction :
Cet indicateur combine la puissance des chandeliers japonais avec le RSI (Relative Strength Index) pour vous fournir des points potentiels de retournement de tendance. En se concentrant sur les zones de surachat et de survente du RSI, et en les couplant avec les formations de chandeliers japonais clés sur les supports et résistances, cet indicateur vise à offrir des signaux de trading de haute qualité.

Fonctionnalités :

Identification des zones de surachat (>70) et survente (<30) du RSI.
Marquage des formations clés de chandeliers japonais qui se produisent à proximité des niveaux de support et de résistance.
Backtesting inclus pour évaluer la performance historique de l'indicateur.
Comment l'utiliser :
Lorsque le RSI est en zone de surachat ou de survente, et qu'un chandelier japonais clé se forme près d'un niveau de support ou de résistance, cela pourrait indiquer un potentiel retournement de tendance. Utilisez ces signaux comme point de départ pour des recherches supplémentaires et en combinaison avec d'autres indicateurs et techniques d'analyse pour renforcer la validité du signal.
