For Aquis Exchange, launched in 2013 as a pan-European challenger to leading incumbents such as Bats Global Markets and London Stock Exchange Group, 2016 was a "transformational year," says CEO Alasdair Haynes. London-based Aquis, which had differentiated itself from the start with subscription pricing, in February 2016 imposed a rule prohibiting "aggressive, non-client proprietary trading." That contributed to a surge in the exchange's average daily value — 79 percent year-over-year in October — with market shares in some top stocks exceeding 6 percent.
"It takes three to four years to get these businesses going," says Haynes, 57, who was CEO of Chi-X Europe before Bats acquired it in 2011. He has formed a separate division for Aquis Technologies. Its turnkey exchange system has been bought by the A2X market in South Africa, and Haynes says that its real-time trade and order surveillance system is meeting healthy demand from organizations coping with the European Market Abuse Regulation and MiFID (Markets in Financial Instruments Directive) II.
