SPY Short 3/22-3/2y below 397!

Always difficult to discern the FOMC announcements, but... I see the potential for a short Wed-Thursday this week below 397 on SPY.

Sold 2 call credit spreads at 397/400 & 397.5/400 respectfully at the end of day Tuesday for expiration 3/24. Will consider rolling this if price moves much high pre-Market/opening minutes Wed 3/22. Will also consider buying a straddle on SPY pre FOMC (maybe?)
