Trading day

What do trading hours and trading day mean?

All times mentioned are in the US Eastern time zone.

Trading days on Nadex start at 6 p.m. of the previous day, run overnight, and end at 5 p.m. Monday through Thursday and at 4:15 p.m. on Friday.

The trading day encompasses both what other exchanges call regular trading hours or the trading session - traditionally the time between the opening bell and the close - as well as after-hours trading.

The week’s trading starts on Sunday at 6 p.m., but it is officially considered the Monday trading day. In notices and other announcements you may sometimes see references to, for example, 'trade date March 2', which would technically begin at 6 p.m. on March 1.
