While in the US market breaks practically always happen when the market is sharply lower, and are intended to halt any downward momentum, in Europe this simple relationship has yet to be perfected, and for the past hour, following what it announced were technical issues, the Deutsche Boerse-owned Eurex derivatives exchange where futures on such indices as the DAX and Switzerland trade, has suspended trading in its T7 system "until futher notice."

Sellers will just have to wait.
