It has been quite a day for tech problems. Trading on the New York Stock Exchange was halted due to a "technical issue" at around 11:30 AM ET this morning. On its status page, the NYSE posted that all trading had been suspended and any open orders would be cancelled -- with a more detailed explanation to follow. A NYSE spokesperson told Forbes that the stoppage came after the exchange "experienced a technical issue" that it's "working to resolve as quickly as possible." An hour before trading stopped, the NYSE reported a problem had been fixed concerning order acknowledgements and connectivity issues. NYSE Arca and NYSE Amex/Arca Options appear to be untouched by the larger issue as they are continuing to operate normally.
