Of course, and I am asking how the CME does it. When they first started the MES/MNQ contracts, certainly they had to insure prices were nearly the same. My bet is they first had to hire some arbitrageurs to do this as just relying on independent traders would not be reliable IMHO.
I completely agree. The first day of trading, during the overnight session, I couldn't place a trade. Got a message that trading was restricted to certain people or something like that. So I'm sure CME was testing out how well the MMs were going to keep it orderly between each other. By the RTH open, I was able to trade it.
Thanks for this valuable feedback. Based on this, I have a funny feeling that rolling out the new micro CL contract is going to go a lot smoother for the CME.
