Don't short any August vol here. I think that's obvious. I would be long AUG2 vol and short JUL26 in long diags, calendars, etc. There is no other trade outside of pure direction. Straddled flies make no sense here. Backspreads are also a no-go into the Fed.
Long JUL26/AUG2 diagonals that you close the morning of the day before the Fed meet.
The GOOGL long diag: Long the AUG2 1200C; short the JUL26 1175C at (4.65 CR) or better.
