Currenex market feed widget for Web 2.0

Playing with Catalyst framework for Perl, we have developed for one of our customers a simple widget that allows you to display quotes received from Currenex.

System consists of several components:

• adapter that implements data exchange through FIX protocol with Currenex and extracts the price (in addition, this same application converts the message format of MarketDataIncrementalUpdate into an internal representation with a further multicast data over the network to all subscribers)
• small client application that performs data collection and store it in shared cache
• controller for Catalyst and a set of JavaScript code based on dojo, intended to update the quotes

Here’s an example widget, built using the iframe:

At this moment application is under active development and adding new features such as intelligent update quotes, ability to modify the style element to the requirements of a particular user, etc.
