Oanda Global Corporation, the online retail trading platform, has been put up for sale by its private equity backers.
Sky News has learnt that the company, which is a rival to the likes of CMC Markets and IG Group, is being marketed by bankers at Nomura and Santander.
Oanda has been owned by CVC Capital Partners, the Amsterdam-listed buyout firm, since 2018.
Its valuation in a potential sale was unclear this weekend.
The company offers trading in foreign exchange, equities, commodities and cryptocurrencies.
Headquartered in Asia, it has a presence in the UK, US and Japan, and serves customers in more than 120 countries.
With more than 100,000 active traders, it is expected record revenues this year of about $175m (£).
Oanda was founded in 1995 and has become a prominent player in the sector, which has boomed in recent years.
Other financial investors are expected to consider offers for the company.
CVC declined to comment.
