Gain Capital Holdings Inc. (NYSE: GCAP) is buying Galvan Research for an undisclosed amount.

Galvan Research, headquartered in London, operates a contract for difference advisory business that provides individual investors with professional advice and trading recommendations in several market sectors. The company will operate as a separate brand and its management team will remain in place.

The deal allows Gain to start building up an advisory service, says Gain CEO Glenn Stevens. The Bedminster, N.J.-based buyer provides trading technology and execution services to retail and institutional investors. The company announced two deals in March for majority stakes in both Global Asset Advisors LLC and Top Third AG Marketing LLC. 

The transaction follows several moves for trading technology and platforms, including Tradeweb Markets' purchase of BondDesk Group LLCin September, and NYSE Euronext's (NYSE: NYX) acquisition of a minority stake in ACE Group Inc., also in September.
