Nadex Refrains from Listing Certain 5-Minute Intraday Currency Binary Contracts and Widens Maximum Acceptable Bid/Ask Spread
In accordance with the authority granted in Nadex Rules 12.27(f)(iv)(5), 12.29(f)(iv)(5), 12.31(f)(iv)(5), and 12.37(f)(iv)(5), due to the possibility of a duplicate strike level conflict, no Intraday 5-Minute Currency Binary contract which would expire on the hour will be listed for the week of January 26, 2015. Therefore, the next expiration to follow the 9:55am expiration would be 10:05am. Likewise, the next expiration to follow the 10:55am expiration would be 11:05am, and so forth.
Additionally, all USD/CHF contracts listed during the week of January 26, 2015 will be settled using a 10 pip wide (rather than a 5 pip wide) maximum bid/ask spread to determine the 10 midpoints used in the expiration value calculation.
