I don't trade any Nasdaq so I can't be sure, but after taking the S55 last week this is my understanding: SuperSOES and Small Cap SOES was replaced by SuperMontage. SNET is still functional. And to answer one of the original post questions, I believe that if you SNET preference an MM for under his posted size that is a liability order and he is required to fill you. Here's some info from Dearborn on the recent changes: http://www.dearborn.com/dfp/include/Series55TestAlert.pdf
dustin, yes, I'm sure you're correct about that, I confused soes and selectnet. shows how much I use either of them.
