For example lets say I have 2000 dollars in my account and I want to buy a call option on ABC that sells at .35 with a strike price of 7.50. It is currently selling around 5.50. I buy 7 calls on it and later on ABC goes up to 10 dollars. Therefore I have to pay 7000 dollars to get my money. Is there a way where I could get that profit, such as using margin? Could you please explain any possibly ways of doing this?
