So, go to the Get Started section and learn the very basics of options trading. Hopefully that will be a good starting point for you on this subject.
By the way, I tend to be a very optimistic guy, so don't feel that this "options puzzle" is a piece of cake. No boy! Options trading is actually very risky and although it can yield much higher returns than directly investing on a stock, it can also wipe out your capital easily and that's why you need to get educated. Never stop!!
