Nadex Adds Discretionary Strike Levels for the Week of January 12, 2015 and Widens Maximum Acceptable Bid/Ask Spread Used in Settlement Process

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 in 12.5, 12.20, 12.51, 12.59, 12.61, 12.63, 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 Wall Street 30, US Tech 100, US 500, and US SmallCap 2000, Germany 30, and Tera Bitcoin Price Index Binary Contracts on January 13, 2015. On January 14, 2015, Nadex added additional strikes due to volatility in the underlying markets in its Daily US Tech 100, US 500, US SmallCap 2000, and Wall Street 30 binary contracts. Finally, on January 15, 2015, due to volatility in the underlying markets Nadex added discretionary strikes in its Daily US Tech 100, US SmallCap 2000, Gold, and Tera Bitcoin Price Index Binary contracts. Nadex returned to its regular listing schedule for all contracts on January 16, 2015.

Additionally, due to the Swiss National Bank’s decision to remove the peg on the Swiss Franc which led to extreme market conditions and a wider than usual bid/ask spread in certain currencies, Nadex widened the maximum acceptable spread between the bid and ask prices in the underlying market that it collects to determine the 10 midpoints used in the settlement calculation process from 5 pips wide to 10 pips in the Daily USD/CHF contracts which expired at 11:00pm and 7:00am ET, and all GBP/USD contracts beginning with the 5-Minute Intraday expiration at 6:40pm ET on trade date January 16, 2015. Additionally, the maximum acceptable bid/ask spread for the Daily USD/CHF contract that expired at 7:00pm ET was widened from 5 pips to 15 pips.
