Flow Traders, an Amsterdam-based quantitative trading house that specialises in exchange-traded funds, says it hasn't had a loss-making day for more than two and a half years.

The company, which listed on Euronext Amsterdam in July 2015, said the growth of the ETF industry was to its benefit in 2016. The more ETFs are bought and sold by investors, the more opportunities there are for Flow Traders' algorithms to make profits through arbitrage.
