There is a pattern, that is not covered by most of the analysts - that is a structure suggested by Trader Evolution, with the WXY from the top, and we are in the final wave of the wave Y. The ending diagonal, according to this scenario, has its limit at 1,77 (you may calculate more precisely yourself - the fifth wave in the diagonal should not be larger than the wave 3).
I think it is a viable option, and will trade it for sure, if it develops.
