The spread between corn and wheat is traded two ways: wheat minus corn on the floor and corn minus wheat electronically. The original configuration of Corn – Wheat Intercommodity Spread Options (corn minus wheat) resulted in quoting confusion. Thus, the exchange has redefined the product as Wheat – Corn Intercommodity Spread Options (wheat minus corn). The re-listing of Wheat – Corn Intercommodity Spread Options is planned for August 9, 2010.
