  Bonjour,

  Votre code a l’air intéressant mais il manque la définition de plusieurs variables. Pourriez-vous les poster SVP ? Merci

  Super merci, c’est un très bon indicateur.

  Pour info j’ai remarqué que lors d’une sortie de range, il y a très souvent un retournement de tendance à la première bougie rouge 😉

  Les ranges sont soit des ranges de continuation (drapeau, fanion, etc), soit de retournement (avec souvent un fake out du mauvais côté).

  Super indicateur, merci beaucoup

   Vous l’utilisez tel quel sur ES et NQ, ou vous ajustez les variables (avec le filtrage) ? Est-ce que le principe reste le même sur tous les timeframes pour les breakout et fake breakout ?

  Quel est l’indicateur que vous utilisez pour les trendlines sur la photo  ?

  Merci encore une fois
