Are those images really showing Head and Shoulder formations or Butterfly? If you say it is head and shoulder, mind pointing out which is the head and where the two shoulders at? Looks to me, you are mixing them up, though any trader that is conversant with pattern formations would agree both can be very profitable trading set ups, if spotted quite early and enough patience to baby-sit the formation, till the picture becomes clearer and "entry point" is triggered.
I wanted to ask the same question, those formation are not head and shoulder to me. Though the market is at resistance leave and there is a probability of the upward trend continuation. My view of the trading trend formation or price action strategy is for a trader should alway look for entry signal and exist signal. My strategy is pin bar entry signal at support or resistance levels.
