Vic Jokovic joins Chi-X Australia as chief executive after 26 years at Deutsche Bank, where he most recently held the role of managing director, co-head of global markets, Australia and New Zealand.
He replaces former boss John Fildes, who announced his intention to step down in April.
Chi-X chairman David Morgan said the search for a new chief executive was "comprehensive" and included international candidates.
"Vic is a high performing and inspirational capital markets executive, with more than 30 years of experience across equity, derivative and debt markets. He is a proven leader with the skills, depth of knowledge and personal attributes to lead Chi-X through the next phase of growth," Mr Morgan said.
For his part, Mr Jokovic said, "I am delighted to be joining Chi-X as it plays an increasingly important role in the development and growth of Australian capital and investment markets.
"By bringing competition and innovation to the Australian financial landscape, Chi-X has delivered substantial benefits to investors and traders in Australian equities. I look forward to leading the team at Chi-X as we build on our position as an integral and innovative marketplace."
