identifying, by a processor, a specification for a non-standardized data object, the specification describing at least a first variable and a second variable associated with an electronic data transaction request message for the non-standardized data object, the first variable and the second variable including an attribute of the non-standardized data object being different from price;

generating, by the processor, price curve graphs for the first variable and the second variable;

displaying, by the processor in an interactive graphical user interface, the price curve graphs for the first variable and the second variable;

displaying, by the processor in the interactive graphical user interface, a graphical aggregation data object describing a price frontier graph based on the price curve graphs, the graphical aggregation data object representative of a plurality of possible combinations of the first variable and the second variable;

displaying, by the processor in the interactive graphical user interface, a price-variable table translating the price frontier graph to a data set;

displaying, by the processor in the interactive graphical user interface, a formula field indicative of the specification for the non-standardized data object;

generating, by the processor, an electronic multi-dimensional data transaction request message; and

transmitting, by the processor, the electronic multi-dimensional data transaction request message to a data transaction processing system as a function of the price frontier graph,

wherein the price curve graphs, the price-variable table, and the formula field are operative to be adjusted via an interaction of a user with the interactive graphical user interface, and

wherein the price curve graphs, the price-variable table, and the formula field are linked to each other.
