The Web site is now offering Level 1 data including bid, offer and current prices along with traded volumes for stocks listed on the RTS Stock Exchange - the exchange that includes the leading Russian securities. Private investors can also track the RTS Index (RTSI), the benchmark of the Russian securities industry.

The service enables ADVFN (www.advfn.com) users to obtain quotes for the RTSI and their desired stocks such as YUKOS oil (YUKOG), view them on monitor pages and place them into their portfolios. They can also look at streaming intraday and historical charts for individual stocks and the index and set up SMS and email alerts according to their own parameters. The site already includes real-time Russian currency prices and will soon be providing Russian financial news and top lists.

"Russia is an exciting emerging market. Private investors' appetite for oil, mining and resource stocks, staples of the Russian economy, makes this market perfect for our large and growing audience," said Clem Chambers, CEO of ADVFN.

Russian prices are the first in a series of foreign exchanges launching on the site imminently.
