Nadex Adds Discretionary Strike Levels and Refrains from Listing Certain 5-Minute and 20-Minute Intraday Contracts

Pursuant to Section 5c(c)(1) of the Commodity Exchange Act, and Commission Regulation §40.6(d)(2)(iv), and by the authority granted by Nadex Rules 12.59, 12.63, and 12.65, due to volatility in the underlying markets upon which the Nadex contracts are based, Nadex added additional strike levels on a discretionary basis in its Daily US Tech 100, Wall Street 30, and US 500 Binary contracts on October 22, 2015. Nadex returned to its regular listing schedule for all Wall Street 30 and US 500 contracts on October 23, 2015. Nadex also added additional strike levels on a discretionary basis in its US Tech 100 Binary contracts on October 23, 2015. Nadex plans to return to its regular listing schedule for these contracts on October 26, 2015.

Additionally, Intraday 5-Minute GBP/USD Binary contracts were not listed until the 6:40pm ET expiration on Sunday, October 18, 2015 (trade date October 19, 2015) due to low liquidity in the underlying market. Nadex also refrained from listing Intraday 5-Minute Binary contracts in the AUD/USD, EUR/USD, GBP/USD, and USD/JPY currencies on October 21, 2015 which would have normally expired at 10:25am, 10:30am, 10:35, 10:40am, 10:45am, 10:50am and 10:55am ET. Finally, Nadex refrained from listing Intraday 20-Minute Binary contracts in its Wall Street 30, US 500, US Tech 100, and US SmallCap 2000 Indices on October 21, 2015 which would have normally expired at 11:00am ET. These actions were taken pursuant to Nadex Rule 12.1(h) (Discretion to Refrain from Listing Contracts) and Subsection (f)(iv)(5) of Rules 12.27 (Currency Exchange AUD/USD Binary Contracts), 12.29 (Currency Exchange EUR/USD Binary Contracts), 12.31 (Currency Exchange GBP/USD Binary Contracts), 12.37 (Currency Exchange USD/JPY Binary Contracts).
