BSE provides access to trading data in the form of a special vendor data flow,
made available on dedicated vendor servers. These servers operate separately from
the trading system.
Connection
BSE's contracted vendors can get access to the trading data in different ways:
-
Directly, by connection, via a leased line, to one of the BSE vendor servers
through the BSE vendor interface. In this case, they shall pay a technical connection
fee.
-
Via Wiener Börse AG. vendor server
-
By connecting to another BSE vendor, thus becoming a subvendor, with access to
BSE data via the vendor’s technical system. In such cases, they have no obligation
to pay a technical fee to BSE.
-
Via TNS (through the Secure Trading Extranet solution provided by Transaction
Network Services).
-
In the subscribes solely to the end-of-day data service, BSE provides the possibility
– for a technical data access fee – of obtaining the data from the Exchange via
an FTP protocol.
In addition to the primary connection, the vendor can also implement a reserve
(back-up) connection to increase operational safety. A back-up connection can
be another leased line or an ISDN dial-in possibility.
Vendor data flow
BSE allows access to three different files on the vendor servers:
-
A real-time file, continuously updated during the day, contains information on
orders and transactions generated during BSE trading.
-
The end-of-day file is uploaded to the vendor servers after trading is closed.
This file contains part of the data originated during the day, the official daily
closing prices and statistics, as well as a list on all products admitted to trading
on the next exchange day, together with their most important characteristics.
-
Since 1 November 2007, OTC transaction data comprising the OTC package can be
accessed in a separate real-time file.
BSE Technical Specifications give a detailed description on technical connection, data transmission and data
formats.
BSE operators provide permanent telephone and email support to the vendor clients,
if necessary, throughout the period when the vendor files are available.
In connection with any other technical questions regarding vendor data services,
please contact the BSE Vendor team.
