RT – Trading on the New York Stock Exchange floor was halted shortly after 11:30 am local time Wednesday, with all screens displaying the “No quotation” message, according to eyewitnesses. “It’s chaos. No one seems to know the root of the cause which seems to me is making everything worse,” a source on the floor of the stock exchange said, according to Bloomberg reporter Leslie Picker. The NYSE is reportedly rushing to fix the “technical problem,” but there has been no official explanation why all floor trading has been halted. The exchange said it was canceling all open orders as well. “We’ve had some technical malfunctions. Some may be related to connectivity with other exchanges. I believe we’re going to have a temporary pause certainly in a variety of stocks perhaps floor wide,” Art Cashin, director of floor operations at the NYSE, told CNBC.
