Well, what to say. You just have to check this contract out for yourself to see if it suits you and your trading style. So far this week, every day has been a nice winner and to the point that it's challenging my ES gains and some days kicking it's butt!
More often than not you will have to pay an extra fee to get this data turned on (free to Open ECry customers), but I would consider turning it on for December (wait until 12/3 to avoid data charges in Nov) and see what you think. I know we had/have some ER2 traders here and I think the CL blows the ER2 out of the water in terms of profit potential.
