An example method to calculate a spread price includes receiving a trading spread including a plurality of legs, wherein each leg of the plurality of legs is associated with a tradeable object. The example method includes facilitating a definition of a mathematic equation that describes a relationship between each of the plurality of legs based on at least two parameters relating the plurality of legs to the spread price. The example method includes calculating the spread price based on the defined mathematic equation. ## Claims ### Claim 1 A method to calculate a spread price comprising: receiving, via an electronic trading device, a trading spread including a plurality of legs, wherein each leg of the plurality of legs is associated with a tradeable object; facilitating, via the electronic trading device, a definition of a mathematic equation to describe a relationship between each of the plurality of legs based on at least two parameters relating the plurality of legs to the spread price, where at least one parameter of the at least two parameters is variable according to changes in a market for at least one of the plurality of legs; and calculating, via the electronic trading device, the spread price based on the defined mathematic equation. ### Claim 2 (depends on 1) A method as described in claim 1 further comprising determining, via the electronic trading device, a calculation sequence based on the mathematic equation and the at least two parameters. ### Claim 3 (depends on 1) A method as described in claim 1 wherein one of the at least two parameters in the mathematic equation is a variable that is to relate one of the plurality of legs to another of the plurality of legs. ### Claim 4 (depends on 1) A method as described in claim 1 wherein one of the at least two parameters in the mathematic equation is a constant that is to relate one of the plurality of legs to another of the plurality of legs. ### Claim 5 (depends on 1) A method as described in claim 1 wherein one of the at least two parameters is to include at least one of addition, subtraction, multiplication, division or delimiter of at least one of the plurality of legs. ### Claim 6 (depends on 1) A method as described in claim 1 further comprising calculating, via the electronic trading device, a plurality of leg values that is to correspond to the plurality of legs. ### Claim 7 (depends on 6) A method as described in claim 6 wherein the spread price is to include the plurality of leg values. ### Claim 8 (depends on 1) A method as described in claim 1 further comprising: facilitating, via the electronic trading device, placement of a trade order to an exchange based on the trading spread, wherein the trade order is to include a leg quantity corresponding to each leg of the plurality of legs. ### Claim 9 (depends on 8) A method as described in claim 8 wherein the trade order is to include less than all of the plurality of legs. ### Claim 10 (depends on 8) A method as described in claim 8 wherein at least one of the leg quantities is zero. ### Claim 11 A method to define a trading spread having a plurality of tradeable objects comprising: facilitating, via an electronic trading device, a definition of a first leg used in the trading spread, wherein the first leg is a tradeable object; facilitating, via the electronic trading device, a definition of a second leg used in the trading spread, wherein the second leg is a tradeable object; and facilitating, via the electronic trading device, a definition of the trading spread to include the first leg and the second leg, wherein the trading spread is based on a mathematic equation that describes a relationship between the first leg and the second leg, and the relationship is based on at least a parameter related to at least the first leg or the second leg, and wherein the parameter is variable according to changes in a market for at least one of the first leg and the second leg. ### Claim 12 (depends on 11) A method as described in claim 11 wherein the first leg is to include a leg multiplier and a leg value. ### Claim 13 (depends on 11) A method as described in claim 11 wherein the parameter is selected from a plurality of parameters. ### Claim 14 (depends on 11) A method as described in claim 11 further comprising calculating, via the electronic trading device, a spread price based on the trading spread. ### Claim 15 (depends on 14) A method as described in claim 14 further comprising facilitating, via the electronic trading device, placement of a trade order to an exchange based on the spread price. ### Claim 16 (depends on 15) A method as described in claim 15 wherein the trading spread is to include at least a third leg and at least a second parameter. ### Claim 17 (depends on 16) A method as described in claim 16 wherein the trade order is to include less than all of the first leg, the second leg and the third leg. ### Claim 18 (depends on 16) A method as described in claim 16 wherein the relationship between the first leg and the second leg is to change based on the second parameter. ### Claim 19 (depends on 15) A method as described in claim 15 wherein the trade order is to include a leg quantity that is to correspond to each of the respective legs. ### Claim 20 (depends on 19) A method as described in claim 19 wherein at least one of the leg quantities is zero. ### Claim 21 A non-transitory tangible computer readable storage medium including computer program code to be executed by a processor, which when executed is configured to implement a method to calculate a spread price, the method comprising: receiving a trading spread including a plurality of legs, wherein each leg of the plurality of legs is associated with a tradeable object; facilitating a definition of a mathematic equation that describes a relationship between each of the plurality of legs based on at least two parameters relating the plurality of legs to the spread price, where at least one parameter of the at least two parameters is variable according to changes in a market for at least one of the plurality of legs; and calculating a leg value corresponding to each of the plurality of legs; and calculating the spread price based on the mathematic equation. ### Claim 22 (depends on 21) A non-transitory tangible computer readable storage medium as described in claim 21 wherein the parameter is selected from a plurality of parameters. ### Claim 23 (depends on 21) A non-transitory tangible computer readable storage medium as described in claim 21 further comprising facilitating placement of a trade order to an exchange based on the spread price, wherein the spread price is to include a third leg price corresponding to a third leg. ### Claim 24 (depends on 23) A non-transitory tangible computer readable storage medium as described in claim 23 wherein the trade order is to include a leg quantity corresponding to each of the respective legs. ### Claim 25 (depends on 24) A non-transitory tangible computer readable storage medium as described in claim 24 wherein at least one of the leg quantities is zero. ### Claim 26 (depends on 23) A non-transitory tangible computer readable storage medium as described in claim 23 wherein the trade order is to include less than all of the legs.
