Streaming market data to a web page? Gissing and Lightstreamer collaborate to provide the answer.
There has been a Gissing ConteX web output handler for some time. This enables the display of market data on a web page, but it involves continually refreshing the page in order to get the most recent information. In response to client demand we've been looking for a solution to enable our clients to publish market data to a web page dynamically so they can see data updates in real time.
There are already a number of offerings on the market which purport to achieve this, but they all require an applet of some kind to be installed on the destination device - and in many financial institutions this is simply not permitted for security reasons. In these circumstances such products simply won't work, either because the firewall at the destination won't allow the data through, or the applet won't install on the destination device because it's locked down.
So we have now entered a marketing partnership with Lightstreamer, an Italian company that has developed a high performance real-time streaming data solution using AJAX, which relies entirely on JavaScript which will work in the restricted security environments that exist in most banks and other financial institutions.
As part of Gissing ConteX R3.73 (see next article) a specific output handler (LIGHTO) designed to provide output data in a format suitable for Lightstreamer's AJAX web server has been released. To make this work you need to license a suitable copy of Lightstreamer (there are various versions depending on the number of servers and clients, and the data update rate). You then build your web site as you want it to work, with the dynamic data in an HTML table on the destination pages.
Of course, if you want to publish delayed data, you can do so by using the Gissing ConteX DLAY added value handler to delay data for up to four hours before it's provided to the Gissing ConteX Lightstreamer output handler.
 Simon Walmsley, VP of Sales at Lightstreamer said, "Our partnership with Gissing Software and the development of a Lightstreamer Output Handler for Gissing ConteX 3.73 enables us to offer a broad range of market data through an off-the-shelf integration with Lightstreamer. Gissing's ConteX architecture makes it very straightforward to stream data to web users from any suitable data source. Our collaboration with Gissing resulted from client demand and we are already working together on a number of deployments."
