If I understand DTO correctly (I may not, although I'm trying very hard to), then spot prices should go up into the next contract, and DTO would lose money during the first week of March over the 2nd - 6th.
I'll stand by the rest of what I said above, but this last part is not necessarily correct. I compared previous DTO prices during that first week, and the price itself may or may not go down even though that is the time when it begins tracking a new contract.
