A data transaction processing system receives and processes equation-based electronic data transaction request messages. Transmitting equation-based electronic data transaction request messages that represent a large series of discrete values reduces the data transmission to the data transaction processing system. Processing equation-based electronic data transaction request messages instead of a series of discrete values reduces the amount of time need to perform transactions, greatly reducing processing latency. Equation-based electronic data transaction request messages can also be efficiently updated by modifying equation parameters, again reducing the amount of data transmitted to the data transaction processing system.
