Orc delivers new version of Orc Spreader

New Orc Spreader 2.0 release adds key features for control,
visualization and systems integration.

Stockholm, SWEDEN, Wednesday May 4, 2011 - Orc Software (SSE: ORC), the
leading provider of technology and services for the global financial
industry, today announced the Orc Spreader 2.0, a new release of its
specialized product for ultra-low latency, high-frequency spread trading
and pairs trading. Firms use Orc Spreader for trading on multiple
markets and across multiple asset classes.

Orc Spreader 2.0 comes with a greatly improved feature set, as well as a
new Spread Monitor offering highly efficient control and overview for
spread traders. Key trading parameters are easily controlled from the
Spread Monitor while integrated P&L provides full visibility of trading
activity. More advanced configuration parameters are displayed in a
separate, user-friendly details window.

“We have developed Orc Spreader 2.0 to meet the latest demands of
traders in highly competitive environments, says Jesper Alfredsson, Vice
President Product Management, Orc Software. “The enhanced ease of use
and automation features offered by the Spread Monitor are only means for
achieving the true design goals for the new release: enabling traders to
make better decisions even faster than before, while reducing errors.
This is what really counts in today's markets where the combination of
precision and speed is key to profitability.”

The new feature set in Orc Spreader 2.0 includes per-leg trading
parameters, trader-defined dynamic trading levels, ability to manually
work hedging orders when necessary and two-way Microsoft Excel
integration using Real-Time Data (RTD). Using the Excel link traders can
view and control any Spreader parameters using Excel, which allows for
great flexibility in using the Spreader as an execution platform
integrated with third party analytics.

We are truly impressed by Orc Spreader 2.0, which offers substantial
advantages compared to our previous spreading tools,” said Brian Avery,
partner, J & A Trading, Chicago. “Orc's advanced trading logic helps us
raise productivity through automation while reducing errors when making
critical decisions in a complex environment. We are also very pleased
with the overall performance and adaptability offered by Orc trading
technology.”

Orc Spreader 2.0 is built on the multi-threaded, server-based
algorithmic trading engine Orc Liquidator. It includes trading logic
designed for spread traders and pairs traders. The server-based
architecture of Orc Spreader 2.0, including an extremely
high-performance trading engine, can be co-located at exchanges
resulting in the lowest possible latency. Orc's extensive low-latency
connectivity to over 100 markets around the world is also available to
users.
