Data feed services & connectivity

The Vienna Stock Exchange offers the data feed services ADH, ADH via Internet and rapidADH to data vendors, investment firms, and any other interested parties. The data feed ADH provides access to nine security exchanges and one energy exchange in one format and via one connection. This substantially reduces costs and work for customers.

If you wish to connect directly to the exchange's data hub to receive, process, and redistribute real-time market data, please contact us at datafeed​(a)​wienerboerse.at.

Both feeds, ADH and rapidADH, can be subscribed to via the same line.

All technical specifications are available for downloading in our closed user group for data vendors.

ADH data feed via leased lines

The ADH data feed was created to offer our customers the enormous advantage of being able to subscribe to market data from many different markets in the CEE region through a single connection. The technology is based on the TARGIN^TM market data dissemination system and the protocol TIP used widely in the industry and features comprehensive data.

Connectivity to the ADH is established via a pair of leased lines (primary and back-up), each with a bandwidth of 10 Mbit/s (standard bandwidth for ADH and rapidADH over one line) per line. The data lines are made available, managed and supervised by the Vienna Stock Exchange.

ADH via Internet

In addition to the ADH data feed via leased lines, the Vienna Stock Exchange offers regional data vendors ADH via Internet through VPN (S2S, IP-SEC). ADH via Internet gives access only to specific exchanges and to selected data content at a reduced but guaranteed bandwidth (256 Kbit/s).

ADH simple TIP client

As an additional service for ADH customers, we offer the Simple TIP Client. This basic software can be used to build an ADH feed handler (further development/embedding required at the customer) and features basic functions such as decoding to ASCII and session handling. The Simple TIP Client may be downloaded from our closed user group for data vendors.

rapidADH – low latency data feed

The high-speed data feed has been specifically designed for an enhanced connectivity to all Xetra® trading platforms, benefiting clients by enabling high-performance and flexible access with programmable interfaces.

rapidADH is based on Deutsche Börse AG's RDI/EMDI/EMDS and bares:

• Design for high frequency and algo trading
• Comprehensive and tick by tick trade messages
• Unnetted pre-trade order book data
• Order book depth of up to 15 levels, depending on the liquidity and asset class

Clients are able to connect to data centers of the Vienna Stock Exchange and leased lines with a recommended bandwidth of 10Mbit/s. The services of rapidADH and ADH can be simultaneously provided via the same lines.
