Nadex Halted FTSE 100 and Germany 30 8-Hour Spread Contracts Listed on July 3, 2017

On July 3, 2017 Nadex submitted to the Commission an emergency action pursuant to Commission Rule 40.6(a), providing notice that on trade date July 3, 2017, due to the July 4th holiday, Nadex planned to close all of its Germany 30 and FTSE 100 Binary and Spread contracts at 1pm ET on Monday, trade date July 3, 2017, rather than their regular close time of 4pm ET due to the possibility of a thinly traded underlying market. However, the Germany 30 and FTSE 100 8-Hour Spread contracts were listed at 8:00am ET with a close time of 4pm ET. The error was discovered less than 20 minutes after the contracts were listed, at which time the markets were halted. All affected parties have been notified.
