USE CASE

Synchronised Calendar for Exchange Systems​

Home » Use Cases » Synchronised Calendar for Exchange Systems​

A “golden source” for prompt, expiry and settlement dates across all exchange applications.

A London-based exchange has a number of internal and external trading systems, all of which must make use of a prompt date calendar, which shows business days when trading can occur. A systems review concluded that a ‘golden source’ was needed for exchange calendar data, including not only prompt dates but expiry and settlement dates.

Sinara was engaged to design and develop a centralised service that other exchange systems could use to obtain this calendar data. The project involved fully understanding the nuances of prompt date calculation–highly configurable contract structures meant that the calculation code had to be sufficiently generic.

Sinara developed a SOAP web service, providing a wide variety of calendar-related functions which other exchange applications could access. Calendar calculations depend on various configurable values in the client’s enterprise data management system, so the service is not tied to a particular prompt structure. Entirely new contracts with new date structures can be added just by adding them to the management system.

The project was also an opportunity for Sinara’s then recently developed Automated Test Workbench to be used in regression testing of the calendar system. Successful completion of the Calendar Data project led to Sinara undertaking several additional projects to integrate the new data source with the other exchange systems.
