What Do Trading Hours and Trading Day Mean?

All times mentioned are in the US Eastern time zone.

Trading days on Nadex start at 6PM ET of the previous day, run overnight, and end at 5PM Monday through Thursday and at 4:15PM 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 evening at 6PM ET, but it is officially considered the Monday trading day. In Notices and other announcements you may sometimes see references to, for example, “trading date July 4,” which would technically begin at 6PM on July 3.

Nadex pauses trading from 5-6PM Monday through Thursday for maintenance and processing. Nadex is closed from 4:15PM ET on Friday until 6PM ET on Sunday.

Advantages for overnight trading

On other exchanges, traders may avoid taking overnight positions. Futures brokers, for example, usually have higher margin requirements for holding trades overnight. And in practical terms, day traders may not want to leave a position on while they are asleep.

On Nadex, there are no margin requirements or additional costs associated with trading overnight. In fact, some traders prefer it. Your risk exposure is limited to the initial trade cost—whatever you paid to buy or sell your contracts. Because the risk is capped on every trade, you can leave a position on with a clear understanding of your maximum possible risk.

Initiating a position the evening before the regular trading session begins in the underlying market can give you an edge, since you have more time until expiration than traders who enter at the opening bell. A contract may cost slightly more to buy in exchange for that edge, since you’re essentially buying an extra 12-15 hours for your trade to develop. Your binary option or spread has greater extrinsic value because of the extra time advantage.

Trading Holidays

Nadex is based in Chicago, Illinois and observes all US national holidays. The exchange is closed on those days and no trading takes place. You can see the list on the Holidays & Hours page.

Because Nadex offers trading across multiple global asset classes, specific markets are closed for trading on the various national holidays that affect them. For example, on Japanese national holidays, trading may be suspended in the Nikkei 225 stock index and Japanese yen-based forex contracts.

Nadex announces upcoming holiday observances in advance on the Notices page. Those holidays will also be listed in the welcome message you see whenever you login to the Nadex platform. The guidelines for how Nadex pauses and resumes trading are shown in the Holiday Product Schedule Guidelines.
