BREAKING DOWN 'Overnight Position'

In forex trades, 5pm EST is considered the end of the trading day. Positions opened at 4:59pm EST and closed at 5:01pm EST are considered overnight positions because a new "day" begins after 5pm. Rollover interest is paid out or received on overnight positions based on the closing interest rate.
