Equiduct, the European share trading platform backed by market-making firm Citadel Securities, is on the hunt for a new chief operating officer.

Willy Van Stappen, Equiduct's chief operating officer since March 2007, left the trading platform last week for personal reasons, the operator told Financial News. He is set to take up a role with French retail broker ProCapital, a subsidiary of Compagnie Financiere Du Credit Mutuel, the company said.
