Why the Whipsaw In Prices Up 5 %, Down 5 %. What's going on guys ? I know why it went up but why is it going down today ? Oil - 1.7 % , NatGas -7.9 % but I don't see this price moderation lasting at all. Where people get hit hard on NatGas is on the March / April contracts if there is too much winter leftovers but hell, we don't know what kind of winter we are going to have.
