The trading blox data has a column called Unadjusted close. The user
is free to use that column. Also, it is trivial to un-adjust the
Open, High, and Low as well. And, there is a column showing which
contract is being used for each row which makes it trivial to
re-adjust prices however you see fit, or not at all.
