Bonjour à tous,

Pour faciliter l'expérience de trading de tout le monde j'ai fait ce script qui colore les conditions de surachat et de survente du RSI et comme bonus affiche les divergences haussières ou baissières dans les 50 dernières bougies (par défaut, vous pouvez le changer). Si vous avez des suggestions ou si vous avez déjà apporté des améliorations, veuillez le signaler dans les commentaires.

Bon commerce et bonne chance!
