CHICAGO and PRINCETON, New Jersey, November 7 /PRNewswire/ --

OES MarketGroup said today that it has continued the global expansion of its customer base with the addition of RTS Realtime Systems Group (RTS), a German-based leading independent software vendor (ISV).

Under the terms of the agreement, RTS will integrate OES's smart order routing technology into its trading applications, enabling equity traders to ensure that orders are routed to the exchange with the best price.

The new alliance brings equity smart order routing and Direct Market Access (DMA) to RTS's customers through multiple execution venues, including NASDAQ, BATS and the National Stock Exchange.
