  Bonjour,
  j’ai établi un code pour lequel je rencontre certaines difficultés.
  Conditions de départ pour définir une reprise de tendance haussière.
  1) sommet 1> sommet 2 et sommet 2 < sommet 3 2) creux 1 > creux 2
  3) Si sommet (S) et creux (C):
  S1 est plus récent que S2 et S2 est plus récent que S3. Idem pour c1, c2 et c3.
  4) S1 est en abscisse avant C1 et C2 est situé entre S1 et S2.
  5) afficher texte sous low C1

  Au niveau des ordonnées cela semble fonctionner mais cela ne marche pas au niveau des abscisses. c’est à dire que je n’arrive pas à bloquer dans mon code un enchainement correct des sommets et des creux.

  Merci à vous pour vos lumières.

  Bonjour LucasBest,
  Merci pour ton retour, ta proposition de code m’a bien aidé.
  Pour que cela fonctionne correctement, je dois simplifier les conditions X et Y comme suit:
  ConditionY = C1y > C2y and S1y > S2y
  ConditionX = S1x > C1x and S2x > C2x

  En effet, il peut y avoir plusieurs creux haussiers entre 2 sommets consécutifs haussiers et/ou plusieurs sommets haussiers entre 2 creux consécutifs haussiers.
  Lorsque l’on calcule S2, S3 et C2, C3 respectivement en fonction de S1 et C1 on n’intègre pas les cas particulières ci-dessus.
  Du coup, le code n’identifie pas la plus part du temps les creux haussiers.
  Je ne sais pas comment modifier le code pour les intégrer, d’où ma simplification.

  Je trouve intéressant ton code pour tracer les lignes de tendances et l’indication du nombre de sommet ou creux touchés.
  Voudrais tu bien me le partager?

  Bien à toi.

  Question:
  J’ai une superposition de résultats au même endroit donc un sur épaississement du texte, etc…
  Comment peut-on éviter la superposition de résultat dans le code?

  Bien à toi.

  Il s’agit d’un de mes 3 indicateurs les plus aboutis ; cela représente des semaines/mois de réflexion et plusieurs heures de code pour arriver à ce résultat… Il est évident que si je devais le poster quelque part, ça ne serait pas ici gratuitement mais sur la marketplace.

  Avec plaisir.

  Je viens de poster un indicateur de supports et résistances (horizontaux et donc beaucoup plus facile à coder). Il faut mixer ce type d’indicateur à celui-ci (dow) pour filtrer les signaux… Mieux vaut peu de signaux, mais une convergence de signes pour ne trader que les setup les plus prometteurs.
