You say that as though they were two semiotically distinguishable activities. Futures trading is wholesale and what we talked about is retail, but they are the same general line of business and if you think no one would ever do it to try to avoid waiting all day for an empty pump, then check out how the 70s oil shock and supply crisis - the last time anyone ever dared "sanction" the U. S. and A. - played out here domestically.

If it is supply you are actually concerned about you buy a couple jerry cans that you keep full. Watching geopolitics to try to time anything still makes no sense.
