What is Open Heartbeat?

Stock quote distribution and management services and applications.

Open Heartbeat is a lightweight data distribution system designed primarily for collecting and distributing rapidly changing price quotes for stocks, securities or other distributable data sets. The core component is a reusable library which manages all communication, synchronisation, caching etc., which can be linked into applications that create or, more commonly, consume data. Primarily aimed at the financial sector, as a way to distribute rapidly changing stock quotes etc., this system can be used for any application that needs to distribute volatile data sets reliably and efficiently. This suite includes a sample feed handler for Yahoo financial data. Use of the data provided by this service is subject to the terms and conditions of the Yahoo real time stock quote service. The library offers very efficient operation (~10,000 updates per second), redundant paths and automatic error recovery and reporting.
