Execute or trade an options contract?
Your math shows that you bought an 'at the money' option for .35 and when the stock is $1 above the strike, your $35 (options trade as a contract for 100 shares) is now worth $100. You knew this, just spelling it out for future readers.  1 - Yes 2 - An execute/sell may not be nesesary, the ooption will have time value right until expiration, and most ofter the bid/ask will favor selling the option. You should ask the broker what the margin requirement is for an execute/sell. Keep in mind this usually cannot be done on line, if I recall, when I wanted to execute, it was a (n expensive) manual order. 3 - I think I answered in (2), but in general they are not identical, the bid/ask on options can get crazy. Just look at some thinly traded strikes and you'll see what I mean.
