Why don't you guys just change to TF.
It acts almost one to one with ER2. Executions are as fast as on Globex and commissions are cheaper than those at CME. Volume should also go up after the change. What you pay for the datafeed you get back in a few roundturns.
Wait a minute. What's going on? This is changing to a different exchange? Won't we be able to trade it through our regular brokers, or do you have to set up a special account through ICE? I know nothing about ICE or this change, so please enlighten me.
