Sell at open. It will probably not reach 220 by then so take whatever profits before Theta takes them away.

It is worth what I bought it for at open, for reasons I don't understand.....  It went up over $10 a share from when I purchased it. 
  
 Edit: Also, I have no idea how the greeks work.   
 Edit2: I researched what the greeks are.  Why is my Delta .03 when the stock price went up $10 from the point of when I purchased it?
