Quote from EricP:
I think Eurex will have greater market share than the CBOT in the Treasuries within six months after launch. There is no reason to believe that they won't. There are only three main factors that should effect market share results:
1) Technology. Eurex provides the current technology (a/c/e) used on the CBOT electronic contracts. Market players will find it easy to switch to Eurex from a technology standpoint. On the other hand, CBOT will be discontinuing their use of a/c/e later this year, causing headaches for existing CBOT clients that are a/c/e users (this is most of them).
