Pic - I think what might have triggered the burst is JP Morgan and the cartel being short the US$.

From Ed Steer this morning referring to Dan Norcini's charts.

"Dan Norcini [of jsmineset.com fame] published some excellent graphs over the weekend. Here's the first one. It shows that the "Commercial Traders" [read JPMorgan et al] are massively short the U.S. dollar index. Do you, dear reader, remember what happened to gold and silver when these fine folks were short both metals as much as that? As Dan says in the sidebar to this graph... "It could well be that the Dollar rally is getting long in the tooth." No kidding!'
