What is the most useful tools for making profits from trading stock options?

There are people who make money trade options, but not for the faint of heart. You are paying a premium for the right to buy or sell shares at a specified price over a period of time. Luck is the most useful tool. If you get lucky and hit a stock during a major move, you will make a lot of money. If you come to a store at the end of your move, you lose the amount paid for the options. The more volatile the stock the higher the option premium. Many professionals use prices Black-Scholes options formula. Look it up on Yahoo to see how it works. It is too complicated to go into here. Personally I think the best way to make money in options is to create requests covered. In this way you get the premium. Of course, if the population makes a big move on you, someone else benefit from it.
