Overnight Trading vs. After-Hours Trading

After-hours commonly runs from the 4:00 PM ET core close until 8:00 PM. Overnight commonly begins at 8:00 PM and continues into the next morning through a separate venue or session.

Important distinction

A market, venue, broker and security can each have different availability. “Open” only means orders may execute in the specific session described.
