Abstract: Systems and methods for dynamically modeling a workflow and identifying parameters in a computing environment are disclosed. In some non-limiting embodiments, the dynamic modeling workflow system may include circuitry, such as a processor, that generates the workflow information to be displayed on a display for a user. The workflow information may contain information representing a first actor configured to perform a first operation and having a first output for outputting first data and a second actor configured to perform a second operation and having a first input for inputting the first data from the first output. In addition the workflow information may be configured to provide a visual representation of the order in which the first actor and the second actor perform the first operation and second operation, respectively, and information about the first data.

Abstract: A computerized marketplace for ratio-based derivatives is provided herein. A method implementing the marketplace includes the following stages: receiving a price query related to a selected derivative on two selected underlying assets, defining a ratio of their respective prices in a specified order, at a specified timestamp; applying a pricing algorithm to the query, to yield an ad hoc return or price of the derivative, relevant to the specified timestamp, wherein the price of the option (or return) is based on an estimated relative financial market performance of the selected underlying assets; and presenting the ad hoc price (or return) of the selected option, wherein at least one of: the receiving, the applying, and the presenting is executed by at least one processor.
