Abstract: Systems and methods are provided in which a first module is configured to execute a trade of a securities futures product on an underlying financial instrument for which a valuation relative to at least one of (a) a net asset value and (b) a closing price, is calculated and published at or after a specified time. A second module determines a price for the executed trade, in which the price is specified relative to the valuation and/or the valuation with a basis adjustment. The second module may be configured to use a price which is (a) a first price which is at a specified discount, (b) a second price which is substantially equal, and/or (c) a third price which is at a premium, to the valuation or valuation with basis adjustment. A third module is configured to submit the executed trade for settlement at the determined price.
