Hi Kris, this is "preferable" conditions, 61.8% is even better than 78.6%, but Butterfly is treated broken if price action leaves initial XA swing. Until this is not happened - butterfly is valid.Thanks for analysis. Don't you think that idea of butterfly is not valid? In harmonic patterns there are some rules either and point B should be max 78.6% retracement from XA I think. Let me know your opinion and if you already seen butterflies with this kind of B location.
