I'm pretty new to options, but i've been doing good so far by just buying low and selling 'em when the value increases. I've got a question about exercising though. Say I exercise one call option with a $5 strike when the stock is at $7. Ignoring fees and stuff, I would think that translates into $200 profit. Since i'm buying the shares though, is there ever any case where the option can be exercised if I don't have $500 (either cash and/or margin) in my account? I don't think it's possible, right?
