The New York Stock Exchange said a manual error caused wild price swings and trading halts for hundreds of company stocks when the market opened Tuesday.

The root cause of the issue, which the exchange operator said has been resolved, was tied to the company’s “disaster recovery configuration” at the start of the day. More than 1,300 trades and some 84 stocks were impacted and marked as “aberrant,” NYSE said in an updated statement on its website.
