  bonjour
  est il possible d’étendre un segment entre deux points sur x barres avec drawray ou autre?

  Désolé je ne sais pas bien la question.

  DRAWSEGMENT trace un segment fixe entre 2 coordonnées.

  DRAWRAY fait la même chose sauf qu’on peut étendre vers l’infini le segment d’un côté ou de l’autre de celui-ci.

  Merci Nicolas

  ma question n’est pas claire
  est il possible d’etendre le segment de 10 barres (par exemple) vers la droite avec DRAWRAY ou autre?

  Je ne veux pas que cela s’étende vers l’infini

  Pour faire cela on peut utiliser DRAWSEGMENT, on lui donne une troisième coordonnées en X et il trouvera automatiquement la valeur de Y en calculant sa fonction affine.

  Par exemple :

  DRAWsegment(barindex, close, barindex[10],close[5],barindex+10)

  1	DRAWsegment(barindex, close, barindex[10],close[5],barindex+10)

  merci Nicolas
  je vais tester cela

  est ce compliqué ensuite de detecter un franchissement de ce segment  dans les 10 dernieres bougies?

  y a t il peut etre un autre indicateur dont jeux peux m’inspirer?

  Il suffit de créer une fonctionne affine et de tester le nouveau niveau calculé sur chaque barre. Le coefficient directeur étant celui-ci : (distance du prix parcourus) / (quantité de chandeliers)

  cela marche nickel pour:

  DRAWsegment(barindex, close, barindex[10],close[5],barindex+10)

  1	DRAWsegment(barindex, close, barindex[10],close[5],barindex+10)

  pour votre derniere reponse

  est il possible de l’afficher comme dans l’exemple ci dessous

  exemple fleche verte quand le triangle est cassé par le haut à la cloture de l’extension du segment

  Nicolas,
  dans votre version ci dessus(triangle-v4.tif), je souhaiterais avoir une alerte ou une fleche quand la cloture casse par exemple à la hausse  l’extension du segment   (cf capture chart ci dessus)

  code ligne 62

  DRAWSEGMENT(High1bar,High1,High2bar,High2,barindex+5)

  Ce code n’est pas le mien, il a été modifié et pas facile à lire. Je l’ai modifié pour tracer des flèches à la cassures des triangles par le haut ou par le bas sur 5 bougies depuis sa création puisque tu étends de 5 bougies seulement les droites.

  C’est un code v11, et c’est une des améliorations de la v11 sur la v10.3, on peut y mettre dans drawsegment un 5ème paramètre pour préciser l’abscisse “x” d’un 3ème point, et cela prolongera le segment suivant la même pente au point x,y correspondant

  En effet, ces deux lignes devraient être comme ci-dessous, cela ne générant pas d’erreurs en v11 à l’époque ..

  DRAWSEGMENT(Low1bar,Low1,Low2bar,Low2) DRAWSEGMENT(High1bar,High1,High2bar,High2)

  1 2	DRAWSEGMENT(Low1bar,Low1,Low2bar,Low2) DRAWSEGMENT(High1bar,High1,High2bar,High2)

  Bonjour Nicolas,

  est-il possible de créer un screnner qui permet de détecter la dernière flêche verte qui alerte sur une sortie de triangle ?

  Merci pour ton retour
