Do some credit or debit spreads.  If SPY doesn't  
 close above $298.08 today I'll make 18% profits.   
  
 That's what I do when im out of day trades, SPY credit/debit spreads based off which way I think it'll go.   
  
 Or just SPY naked calls/puts.  Buy at close, trying to predict post and pre market direction, and then sell right at open tomorrow.

Yeah, problem is, that doesn't really work when you're in on something with big gaps between the strikes relative to the price of the underlying (I'm looking at you $RAD).
