  Bonjour

  Je cherche à transcrire ce code Harmonic Trading.lua de la plateforme de fxcm marketscope2.0 pour pouvoir l’utiliser sur PRT, est ce possible ?

  Merci

  bonjour

  merci pour l’info

  je l’avais bien vu car avant de poster ma demande j’avais chercher sur le site pendant une bonne partie du week end

  mais c’est un des Harmonic Patterns – Bullish AB=CD

  avec ce fichier coder en lua on peux détecter les figurer en “Bat”, “Gartley “, “Crab”, “Butterfly “, et aussi les Bullish AB=CD

  voilà exemple ci joint.
