  Bonjour Nicolas,

  Auriez-vous la possibilité et le temps de créer un screener basé sur la flèche verte (signal ACHAT) à partir de l’indicateur “Q-trend” ?

  –> https://www.prorealcode.com/prorealtime-indicators/q-trend/

  D’avance merci pour votre aide et contribution.

  Bonne journée

  François
