GAIN Capital Launches New FOREX.com Arabic Service

NEW YORK, LONDON and ABU DHABI, United Arab Emirates, April 21, 2010 - GAIN Capital Holdings, Inc., a global provider of online trading
services, today announced that it has launched a new Arabic service under its
FOREX.com UK division.

The new service will offer FOREX.com's award-winning trading platform and
services to clients across the Middle East region. The FOREX.com offering
supports margin-based trading in FX and Contracts for Difference (CFDs), and
is regulated by the FSA through FOREX.com UK.

Investors in the region will be able to trade in oil, gold, silver and
the world's major currencies including the U.S. Dollar, Euro and British
Pound, 24 hours a day, five days a week. FOREX.com also offers access to the
firm's unique research resources, including daily market commentary and
analysis from a global team of economists and technical analysts.

The retail foreign exchange market is experiencing tremendous growth
worldwide. In the Middle East, it is a relatively new phenomenon for retail
traders but demand is soaring as the appeal of this market is increasingly
recognised. In the first quarter of 2010, trade volumes in currency, gold and
crude oil futures grew by over 120% according to recent reports.*

Glenn Stevens, chief executive officer of GAIN Capital commented: "As we
continue to expand globally we are delighted to launch our new local offering
in the Middle East. The impressive growth of retail currency, gold and oil
products in the region in recent years has driven our decision to enhance our
offering for Arabic speakers. Traders in the Middle East will now have access
to our award-winning trading platform and expert research as well as personal
support around the clock."

As part of the service offering, FOREX.com provides a wealth of free
educational resources including online guides and courses, and access to
dedicated support from forex experts seven days a week. The comprehensive
service has the additional benefit of offering clients segregated funds
protection offered by an FSA-regulated business.

To support the new service launch, FOREX.com is attending a number of
conferences in the region. On 3 and 4 May 2010 it is attending the Jordan
Expo, and on 21 and 22 May the team then moves on to the Lebanon Show which
is one of the biggest FX trade shows in the region. At both conferences
FOREX.com will showcase its new service offering and platform.
