Turquoise CTO exits as London Stock Exchange takes the reins

Karl Flinders

The CTO of trading venue Turquoise has left his role following the takeover of the company by the London Stock Exchange.

Yann L'Huillier left Turquoise on Friday after it was mutually agreed that his role would not fit into the new London Stock Exchange structure.

Last week, the London Stock Exchange appointed Mark Ryland, previously head of technology at Baikal, as head of technology at the combined Baikal/Turquoise unit.

L'Huillier, who starts a new job in April at a major financial services business, said the decision was mutual and a natural progression.

He told Computer Weekly, "The first part of the Turquoise story is complete and the second part will be done by new people."

L'Huillier joined as CTO when Turquoise was launched and built the Turquoise IT infrastructure from scratch using highly customised off-the-shelf software.

As well as his work at Turquoise, L'Huillier replaced the entire trading system at the Toronto Stock Exchange in 2001 and replaced the system used by the Boston Stock Exchange in 2005.
