With current trade tensions between US and China, and the impending supply disruptions of Venezuela, Iran and Libya, the uncertainty is causing oil to whipsaw. I would recommend a small position short on WTI and long position on Brent because the impact on US oil exports to China will create downward pressure while non US oil exporting nations are less likely to be affected by this short term bearish pressure. Instead, Brent is more concerned over whether the increase in production of Saudi and Russia can keep up with supply disruptions of Venezuela, Iran and Libya.
Alternatively, Selling out of the money puts on oil (below 63 dollars a barrel) is generally a safe bet. However, personally I feel that entry into this options trade would be better after the next downward price correction kicks in.
