"Following the successful launch of the new market model by Euronext.liffe Brussels and the related increase in trading volumes, the range of strike prices needed to be expanded to make it easier to respond to different market situations," said Erik Bevers, a market maker at Delta Lloyd Securities N.V.
Since the new market model was launched in Brussels on 24 January 2006, equity option trading volumes have increased by over 40% compared with the same period last year.
