GAIN Capital Launches Forex.com in Australia

NEW YORK, LONDON and SYDNEY, April 28, 2010 - GAIN Capital Holdings, Inc., a global provider of online trading services
specializing in foreign exchange (forex or FX) and contracts for difference
(CFDs), today announced the launch of a new service in Australia under its
FOREX.com brand.

The new Australian Securities and Investments Commission (ASIC) regulated
offering makes FOREX.com's award winning trading platform and services
available to clients in Australia, New Zealand and the wider Asia Pacific
region. FOREX.com has opened an office in Sydney to provide local customer
support and service.

Glenn Stevens, chief executive officer of GAIN Capital commented:
"Launching operations in Australia is part of a long term strategic goal to
service our clients locally wherever possible. GAIN Capital has a growing
global footprint and we believe our FOREX.com service will be well-received
by traders in Australia and New Zealand who are looking for a
well-capitalized firm that offers premium trading tools and research,
competitive pricing and, of course, a solid reputation."

The retail forex market has experienced impressive growth in the region
in recent years. According to independent research firm Investment Trends, FX
trading now accounts for up to 25% of trade volume amongst some providers in
the Australian CFD market - a market that has until recently been dominated
by equity trading*. GAIN Capital expects this growth to continue as traders
look for markets that offer the potential for returns whatever the economic
conditions.

Investors in the region will be able to trade in the world's major
currencies including the Australian Dollar, New Zealand Dollar, U.S. Dollar,
Euro and British Pound, as well as gold, silver and oil CFD contracts.

Customers will also enjoy access to the company's full suite of trading
tools and services, including:

    - Real time forex news from Dow Jones.
    - Expert research and trading ideas from a global research
      team of technical and fundamental analysts.
    - Free educational resources including online guides, courses,
      webinars and more.
    - Local funding options and account services such as
      Australian dollar (AUD) and New Zealand dollar (NZD) denominated trading
      accounts.

Mike Bermingham, Regional Director of FOREX.com Australia added: "With
the opening of our office in Sydney we look forward to providing
on-the-ground support to our clients in the region."

With offices in the U.S., U.K., Hong Kong, Japan, and Korea, the launch
of operations in Australia extends the company's global footprint to six
countries. More offices locations are expected to open later this year.

* According to independent research firm Investment Trends, geared
trading instruments are a rapid growth area in Australia(1), and FX trading
makes up around a quarter of the volume of trading through several of the
local Contracts for Difference (CFD) providers(2).
