They're digging their own grave by doing this as much of the volume has already disappeared from the YM. I swear this damn contract runs on a Commodore 64 as it is, except the C64 was a stable machine. I think you'd have to be crazy to pay for the feed and continue trading this sinking ship. opm8
Since it's going to globex, if you pay for the ES data feed, do you think the YM will be included? I'll bet theyll charge separately to get more money out of people.
