s'il vous plaît aidez-moi à mettre une flèche d'achat et de vente sur ce code.

Vérifiez le dossier "Projets" dans MetaEditor.

P.S. Pour l'optimisation il est nécessaire de limiter le nombre de barres pour dessiner les flèches.

Mais ce ne sera pas le cas aujourd'hui.

Joindre le fichier de la version "1.04".
