WHO sold you that?

Ah-Hmm. How do you think most traders are going to want to answer that question?  Goldman's customer base ought to be shrinking pretty fast ...like that glacier in Iceland.   And without a customer book to trade against it's a little tougher to sustain unbroken winning trade days.. 
Still it has some value...

Definitely worth looking at after a 50% retrace...say 120, though I personally like the .618 around 100.
