I have access to Eurex US, and let me tell you, it is terrible right now....it follows the US contracts, but hardly trades..maybe a few thousand per session, i've actually completely stopped looking at it. Esignal, Trading Tech, & CQG are offering the exchange at no cost, but at this point it simply is not worth the time.
Also, i'm not sure how many of you actually trade Eurex products, but beginning in either June or July, you will need to have a "User ID" to access the market. Meaning, you have to take the Eurex exam to become an "approved trader" (in eurex's words). Anyone can pass it, it'll just take abit of money and alot of time....i compare it to the Seris 3 test for futures.
