For whatever reason, I've always found that trading the 'old' contract on rollover day and then switching to the new contract on friday works best for me. The volumes of each should be very comparable tomorrow I believe. On friday, though, March will be dry as a bone 

Quote from Gabfly1:
Not if you are talking about the indexes traded on the CME. The front month volume rolls like clockwork on the basis I explained in my earlier post.
