Knight Launches Oasis Small- and Mid-Cap Algorithm for European Equities

JERSEY CITY, New Jersey and LONDON, April 20, 2010 - Knight Capital Group, Inc. (Nasdaq: NITE) today announced the launch of
Oasis, a smart order execution algorithm that sources small- and mid-cap
liquidity, for European equities.

Oasis uses innovative logic to source liquidity in thin and
difficult-to-trade names with increased efficiency and opportunities for
price improvement as well as greater fulfilment. The strategy evaluates
liquidity, volatility, price trend, momentum and other characteristics in
real time to determine the best sources of liquidity to help minimize market
impact. Oasis also includes anti-gaming procedures such as continuous
monitoring for adverse trading behaviour to further help minimize information
leakage.

"Knight does not subscribe to a one-size-fits-all approach. That
philosophy has led Knight to become an innovator in creating new categories
of algorithms, including situation-specific algorithms like Oasis," said
Bradley Duke, Managing Director at Knight. "Higher volatility, reduced
liquidity and wider spreads are just a few of the challenges associated with
trading small- and mid-cap stocks. Knight has deep expertise in these often
thinly traded names as well as in the complexities of trading across the
fragmented European marketplace."

Oasis is a new addition to Knight's Algorithmic Suite for European
equities. The algorithms are powered by FAN(TM), a smart order execution
algorithm which sources liquidity from multiple exchange and MTF destinations
simultaneously while adapting to market conditions in real time and
re-circulating orders to where executions are occurring.

Oasis and Knight's entire Algorithmic Suite are accessed through Knight
Direct, Knight's multi-asset class execution management system, as well as
through a number of third-party execution and order management systems via
Knight Direct's FIX capabilities. To learn more about Knight's European
algorithmic offering, please contact Bradley Duke at +44-20-7997-7818 or
