Data Feed Connectivity Solutions

Barchart / DDF provides a variety of connectivity options for the delivery of our market data feeds. Our connectivity solutions are scalable and include:

• internet
• direct line/circuit
• co-location at Equinix or via Amazon EC2
• cross-connects from exchange points-of-presence

Adding exchanges is quick and efficient using one of our high performance APIs (.Net or Java) or by writing your own API to our middleware. Barchart offers consolidated and compressed market data delivered in DDF format that maintains the speed, accuracy and reliability of tick-for-tick raw exchange feeds without a high consumption of resources.

Additionally, Barchart offers exchange point-of-presence co-location or cross-connects and the option to develop directly to raw exchange formats, like: FIX/FAST, CQS, CTS, UTP or BBDS.

The convenience and reliability of the internet has made it a conventional way to deliver market data.  Through proprietary compression and reliable packet delivery technologies, Barchart is able to utilize the internet to distribute our market data feeds.  Internet delivery may be used for connectivity directly to your data center for front or back-office use, as well as direct to an individual’s desktop application.  Barchart maintains connectivity to the major internet service providers ensuring the most high-speed and direct paths of delivery.

Internet (HTTP) is also used to deliver our real-time or delayed snapshot data feeds via web services (XML or CSV format), as well as end-of-day and historical time series data.    

For ultra low latency requirements, Barchart offers the flexibility to relay raw exchange data (original format) directly from the Equinix data center facility in Chicago, IL.  With multiple exchange points-of-presence, the Equinix facility offers an ideal co-location or cross-connect solution. Our presence at Equinix provides Barchart the capability to offer market data delivery via the internet, cross-connects or direct line to your data center(s) utilizing various telecommunication carriers.

Barchart maintains virtual data centers within the Amazon EC2 cloud providing an additional connectivity option.  This connectivity method allows your organization to benefit from cloud computing using virtual servers.

Other Information

Barchart offers traditional UDP and TCP transfer protocols as well as a third option that is highly configurable, fast and firewall friendly to distribute our market data. This protocol is a hybrid transfer protocol that provides TCP guaranteed delivery and uses UDP to transfer market data with reliability and congestion control.  This option provides even faster delivery, lower latency and reduced levels of packet loss that may be associated with standard UDP.
