I could be wrong, but it will probably be quite sometime before volume on the ICE gets anywhere near the volume on the globex. I certainly want to trade the er2 where the volume is.
I doubt it will ever reach CME volumes. For a start if they make the big contract electronic aswell as the small contract, this will split volume. Hopefully for us smaller traders the big contract wont take off. Anyway we will soon know....
The new contract (RUT) has traded 171 contracts so far...I would expect that ER2 on the CME will remain at current liquidity levels, or even increase until September...unless ICE is smart and pulls a stunt like waiving fees for a few months to attract traders
