Honest question, do you know the mathematical equation that is used to determine option value? Do you understand what the Greeks represent? 
  
 Do some research on this and you'll get your answer

Okay, sorry for the misunderstanding. ofcourse I know the greeks, I know time decay causes value loss, But I am talking about INTRA DAY. In the above image at the end of graph fb fell a little bit from the days local maximum, but option fell drastically. Technically, theta should affect the price next day.
