Trading on the NYSE Arca resumed around 11:05 a.m., ET, after being temporarily suspended at 10:50 a.m., ET, on Monday.
The suspension was due to the rollback of software updates made over the weekend. The technical issue has since been resolved and all systems are functioning normally.
Existing orders before the suspension were not cancelled, but orders made during the suspension were scrapped.
