Project Turquoise, the putative trading platform which has been dogged by delays since its inception last November, has appointed a senior executive from the Boston Stock Exchange, which was forced to close its equities market in September, as its chief technology officer.

Yann L'Hullier, the senior vice-president and chief information officer for the Boston Stock Exchange, will join Turquoise on November 25, reporting directly to Eli Lederman, the chief executive of the company. This is the first hire by Turquoise since Lederman's appointment three weeks ago.
