Oil trading making you dizzy?

Back into USO again today.  Price dropped to the $35/$36 range I have been using as an entry point.  Did a covered call -- bought USO at 35.83, sold Oct 36 calls (UBOJJ)  to open at 1.45 for a net investment of 34.38.  Maximum profit is 1.62 per share with USO above 36 at expiration--4.7%.
