Hi All, That is not investment advice, there was butterfly harmonic on Alcatl 4h graph please check the related link given below for alcatl Second harmonic pattern is crab AB=CD signal is minimum requirement for butterfly harmonic ıf not, pattern is invalid. 1.27AB=CD is expected for butterfly that is valid signal. When priceaction is reached PRZ that is opportunity for short trade setup. Again not investment advice, dont get position accoding to my work Good luck Harmonic Trader.
