The NASDAQ Opening and Closing Crosses are price discovery facilities that cross orders at a single price. The crosses enable market participants to execute on-open and on-close interest and provide unparalleled transparency. Market makers and other industry professionals have repeatedly demonstrated their willingness and ability to offset imbalances that are entered into the cross. The crosses generate opening and closing prices that are widely used by industry professionals including Russell Indexes, Standard & Poor’s and Dow Jones.
