QuoteLink groups data available from different data providers and make it available in a consistent way to different applications. This is achieved using a common framework. Other applications notably Microsoft Excel connect to this framework to present the data to user.

This process can be divided in four main parts:

• connect to the exchanges and send the data over the internet

• collects data from the providers
• data processing
• offers common interfaces to other applications (RTD, COM , .NET)

• further processing
• presentation

Feeds are either based in direct connections to external the servers or based in connections to data providers applications running on the client machine (for instance TWS interactive brokers). This structure may include several and feeds and applications running in different machines.
