EXK...interesting structure

EXK is currently showing an interesting wave structure...the choppiness (see white circle) nad overlap is making this look like a leading expanding diagonal...not the most typical way to start a wave 3, but not a violation of any EW rules/guidelines that I am aware of. I first thought this might be an expanded flat correction of the wave 1 of a higher degree, but given that what would have been the B wave is exceeded 1.618 of the A wave down (ABC immediately following the wave 1 of a higher degree), I must rull out the expanded flat option and go with the leading diagonal...but I admit that I do not like it. Lets continue to watch closely.
