Today was the first installment on changing the common view on oil. As Daytrading ES pointed out lots of media narrative about record production levels. Also they have made it clear to everyone that the shale guys have been selling a big chunk of 2017 production at these prices.
This morning Genscape saying big Cushing build. Tomorrow afternoon good odds that API will confirm followed on Wednesday morning by EIA and then of course the Friday rig count, an avalanche of bad news. Don't forget it is winter blend for gasoline so the European refiner surplus can be sold anywhere in the US. Late last winter blend season they ran out of storage for New York Harbour RBOB. They already ran out of oil storage in Rotterdam this fall.
Point being you have to seed doubt into the minds of all the new oil longs then you can use what will undoubtedly be some horrifically bad inventory reports to start the panic selling. Rinse wash and repeat.
