I agree with setharb - pit-traded products are just no way near as attractive for retail traders compared to electronic stuff. The prices are opaque, fills are terrible, and commissions are higher due to higher cost & overhead.
The exchanges in question should go electronic - they would then see volume soar, just like we saw with the Emini.
I personally would trade the commodities FAR more if they were electronic. I have often passed on a trade because I have a competing trade in an electronic market, and I always go with the latter. So these guys are just shooting themselves in the foot. It's those annoying NYC and Chicago locals who want to preserve their no-talent monopoly on order flow - they run the exchanges so they don't want to give up their nice little earner, just like the NYSE specialists. IMO Eurex USA should just list *all* pit-traded products and put these clueless dinosaurs out of business. Then they will have to learn how to actually trade rather than just front-run paper and back away from anything bigger than a 1 lot.
