GAIN Capital Holdings, Inc. was a US-based provider of online trading services, headquartered in Warren, New Jersey until it was acquired by StoneX Group in 2020.[1] The company provided market access and trade execution services in foreign exchange, contracts for difference (CFDs) and exchange-based products to retail and institutional investors. Trading was provided via one of two electronic trading platforms, its own proprietary FOREXTrader PRO later renamed as StoneX Pro and MetaTrader 4. GAIN Capital allowed retail and institutional clients to speculate on global foreign exchange markets in what is known as ‘margin forex trading’.
GAIN Capital operated retail foreign exchange and CFD trading brands, Forex.com and City Index as well as GTX, a fully independent FX ECN, a multi-dealer foreign exchange trading platform, for hedge funds and institutions.[2] It also owned advisory CFD business, SALT Invest, and futures provider, Daniels Trading.[3]
