Systems and methods for trading using an embedded spreadsheet engine and user interface

A computer-implemented method for generating a trading message using a trading application comprising an in-process embedded spreadsheet engine, the method comprising:

• receiving values for a trading-related parameter into an array in a dynamic cache communicatively coupled to an embedded spreadsheet engine that accesses data in the array in the dynamic cache using keys based upon one or more parameters in a function that defines the array, data in the dynamic cache being stored in key-value pairs;
• generating a display of the array using a spreadsheet user interface communicatively coupled to the embedded spreadsheet engine, the values being updated according to a specified condition defined by the function;
• generating a trading trigger using at least some of the values in the array;
• and
• responsive to the trading trigger yielding an affirmative trading trigger, generating the trading message.

A computer-implemented method for facilitating publication of and subscription to trading-related information among a plurality of third parties, the method comprising:

• receiving a content service registration from a publisher user using a first instance of a trading application;
• responsive to receiving a request from a subscriber user to subscribe to the content service, the request being generated by a second instance of the trading application in which a subscriber user entered a subscription request into a user interface of the second instance of the trading application, the request comprising a unique identifier of the content service, associating the subscriber user with the content service;
• and
• responsive to receiving a content message for the content service from the publisher user, the content message being generated by the first instance of the trading application in which the published user entered a publication request into a user interface of the first instance of the trading application that causes the content message to be published, the publication request comprising the unique identifier of the content services, broadcasting the content message.
