Regardez celui-là : https://www.mql5.com/en/forum/general

Définissez la période du ma rapide à 1 et alors ce sera la même chose que si le prix traverse la moyenne mobile (le slo ma).

Excellent ! Merci mladen

Comment ajouter une alerte sur le smartfone ?

Le code est :....

.... mais l'alerte s'affiche à chaque bougie ! !!

J'ai le numéro 'push' MetaQuotes ID.

Test OK.

Quel est le problème ?

Test OK.

Qu'est-ce qui ne va pas ?

Vous n'avez pas de critères qui détermineront quand la notification doit être envoyée (quelque chose comme "if (condition==true) SentNotification("alert") ;). Ajoutez le critère "if" quand il doit être exécuté.

Et il devrait être dans la procédure de démarrage et non dans la désinit (puisque la désinit est exécutée uniquement lorsque l'indicateur est arrêté pour l'une des raisons).
