New Web Toolkit for easy Development of Customised Financial Websites

Innovative web tools enable developers to build new or enhance existing websites with minimum programming work and cost

Frankfurt, Germany, 14 October 2009 – Interactive Data Corporation (NYSE: IDC), a leading provider of financial market data, analytics and related solutions, today announced that its Managed Solutions business has launched an innovative Web Toolkit that can be used by IT departments to build customised, state-of-the-art financial websites and applications for the Internet and intranet without generating a high level of programming work or cost. The new tools have been added to Interactive Data’s PrimeDeveloper offering.

Web Toolkit offers a choice of modules, templates and grids to help create customised designs, combined with an extensive library of pre-developed widgets such as charts, indices, watch lists, top-flop lists, currency calculators, tag clouds, heatmaps and market news or fact sheets on individual asset classes. Transaction-based portfolio applications, including performance information, alerts and trade data, are also available. Developers can use these building blocks to simply drag and drop the tools into the desired layout – including corporate templates – to create customised, state-of-the-art visualisation of financial information.

PrimeDeveloper Web Toolkit is fully integrated with Interactive Data’s fast and flexible market data platform, which is designed to standardise structured and unstructured market data from around 200 global content suppliers. External data, as well as proprietary content, can be seamlessly integrated via push or pull delivery. Entitlement, permissioning and reporting services form part of the offering.

“Web Toolkit is designed to minimise the development outlay when building financial information systems – without reducing the level of customisation,” says Carsten Dirks, managing director of Interactive Data’s Managed Solutions business. “We regard Web Toolkit as an important technical milestone that can help support IT departments’ up-to-date integration environments and make it easier for them to manage and develop their applications.”

Interactive Data’s PrimeDeveloper service offers IT departments and software firms a range of tools to help them develop new or expand existing websites quickly and efficiently. Application programming interfaces (APIs) for PHP, .NET, Java and JavaScript programming languages provide real-time, delayed or end-of-day access to a wide range of international financial information, including securities pricing, company and capital markets data, as well as news. The PrimeDeveloper offering also includes training, documentation and support services.
