From Traiana's significant growth, positioning it as a global player in pre and post trade services through to the transformation of ICAP's electronic FX and fixed income businesses into a fully integrated multi-product offering. I have decided that it is a good time for me to start a new chapter."Although I have decided to leave, I believe that EBS BrokerTec is exceptionally well positioned for growth".Mandelzis joined ICAP's e-trading and technology solutions provider in December 2014, and was responsible for the EBS BrokerTec, foreign exchange and fixed income business at ICAP.Gil is a member of ICAP's global executive management group since 2009.
