In the mid 90's I did quite a bit of stock trading. Once I got into futures 14 years ago, I rarely trade stocks. I for one am very thankful that CME even exists, for a wide variety of reasons. They also continue to introduce micro contracts that are liquid enough and very utilitarian; as just one example the MHG, micro copper has made me some nice dough recently. Thanks to their efforts to build a world-class operation, I have the key futures market vehicles I need to make a living. Long ago I stopped using ICE, they shot themselves in the foot when they started charging a ridiculously large monthly fee for access to their precious data and platform. Perhaps some day they will reverse course, their dollar index was a handy tool many years ago for me.
