Thanks everyone for posting. I have been using CMEG since April. I have experienced a few glitches here and there, but I have not incurred a loss as of yet. This SSR issue however sounds like a huge problem. It is one thing to be blocked from entering a short position during SSR, but it is unacceptable that you can't exit a long position and they are acknowledging that their system is the problem and saying it is just part of the risk of trading. This, along with the recent big jump in thier ECN fees, just may be a deal breaker for me.
