BSE-Sofia has implemented Deutsche Boerse AG's electronic trading system XETRA.
XETRA is one of the most powerful trading platforms for cash market securities and is a synonym for the electronization and internationalization
of securities trading. Deutsche Boerse has been using Xetra® to operate the trading platform for the Vienna Stock Exchange since November 1999,
and has been doing the same for the Irish Stock Exchange in Dublin since June 2000. Furthermore, trading on Eurex Bonds and Eurex Repo, as well as
electricity trading on the European Energy Exchange in Leipzig runs entirely through Deutsche Boerse technology. The Shanghai Stock Exchange, which
operates China's largest equity market, will be using Xetra® technology as the core element of its new trading platform in the future.
Generally XETRA's market model includes the trading forms auction and continuous trading for on-exchange trading. Additionally, Xetra provides
IPO and OTC-entry functionalities.
Trading hours vary according to the type of the financial instrument and the type of the market it is being traded on.
The financial instruments with low liquidity are traded two times per a trading session in pre-defined auctions, while all the other instruments are traded
in continuous trading.
The settlement is done on the "delivery versus payment" (DVP) basis via the computerised book-entry system of the Central Depository AD.
A transaction fee will be paid to the Exchange by both parties in a transaction, where as it will be calculated as a percentage of the respective
total value transacted.
