  Bonjour Nicolas, Bonjour à tous.
  J’ai découvert il y a quelques semaines un oscillateur que je trouve simple et utile sur tradingview. Le code ne semble pas compliqué mais je suis bien incapable de le convertir en language PRT.
  Peut-être que l’équivalent ou presque existe déjà.
  Est-ce que quelqu’un serait en mesure de convertir ce code. Je fais figurer une image pour l’illustrer. La ligne verte peut être interprétée comme une force acheteuse, la rouge une force vendeuse, la jaune une ligne “signal”

  Bonjour, tentative de conversion à tester, en attendant que Nicolas, bien plus habitué à faire les conversions, passe par ce post et valide ou corrige:
