So obviously the DD is a huge failure, with only 10-20 contracts trading per day. There has also been a large decline in interest in the YM since the increase in CBOT exchange rates, which has renderred the $5 dow mini to look comparatively worse to competing products at the CME. Moreover, the YM now does 1/2 the volume of the ER2 in what used to be two products which had similar daily volume. And less than 10% of the volume of the ES. Now to the DD, which consistently has a 2 tick spread, rendering it useless compared to the fungible YM with 0-1 tick spread. I believe when the CBOT released the DD, they thought the opposite would occur. Namely, the 1-2 tick spread would be in the YM, not in the DD. So my question is would trade the DD if they eliminated the spread by doing away with the YM?
