I've been trading copper alot lately and was wondering how many people trade it? Its pretty thin compared to ES but about the same as CL or 6E. There are some very nice rotations and seems to get a good bounce off obvious levels. I use the dollar as a corralated market in an inverse look but what else should i be looking at. I would like to even perhaps start a metals room. I'll foot the bill for the room if a few metals traders would be interested.
