screener semaphore quadratique

J’étais pourtant persuadé d’avoir déjà créé ce screener, mais j’ai rien retrouvé 🙂 Bref, le code ci-dessous détectera les retournements haussiers (point rouge) et baissiers (point bleu).

screener[blue or red]

Bonjour Nicolas,

Il y’a un décalage de 5 bougies entre les signaux screener et l’indicateur. Je n’arrive pas a aligner tout ça. Est il possible d’avoir de l’aide?

Merci
