A system and process for use in transacting an expirationless option on a particular asset is described. A user using a video display (220) is prompted to input data representative of a particular asset, the option type, an exercise price, the current price, the historic price volatility and the margin requirement for the particular asset. These data may be also obtained from a data source (130) and are later stored in a storage medium (250 or 350). This data is used in an algorithm for obtaining the option premium data for use in transacting the expirationless option. As shown in the figure each end user workstation 120 preferably includes a microprocessor 210, a video display 220 (e.g., a CRT projector or monitor), a keyboard 230, a mouse 240, a printer 260, and a storage medium 250 (e.g., a disk array, tape, optical drive, tape drive or floppy drive). The end user workstations 120 may be an IBM compatible PC, laptop, or pen computer running Microsoft Windows 95 or its equivalent.
