How are you going to make trading decisions? Based on your gut intuition or something your wife believes about a stock? Trading on instinct can be entertaining and fine if your goal is to lose money—but if you want to make money, you need to get yourself a trading method! A trading method gives you an edge that allows you to identify patterns in the market and profit off of them. You can find strategies to trade free online on trading sites. You can also purchase them, but I recommend you start out by testing free systems, because oftentimes you can find what you need without spending money.
A binary option is a financial exotic option in which the payoff is either some fixed monetary amount or nothing at all. The two main types of binary options are the cash-or-nothing binary option and the asset-or-nothing binary option. The former pays some fixed amount of cash if the option expires in-the-money while the latter pays the value of the underlying security. They are also called all-or-nothing options, digital options (more common in forex/interest rate markets), and fixed return options (FROs) (on the American Stock Exchange).
