A binary option is a financial 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 cash-or-nothing binary option pays some fixed amount of cash if the option expires in-the-money while the asset-or-nothing 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)
Binary options “are based on a simple ‘yes’ or ‘no’ proposition: Will an underlying asset be above a certain price at a certain time?” Trades place wagers as to whether that will or will not happen. If a customer believes the price of a commodity or currency will be above a certain price at a set time, he buys the binary option. If he believes it will be below that price, he sells the option. The price of a binary is always under $100.
In finance, a trading strategy is a fixed plan that is designed to achieve a profitable return by going long or short in markets. The main reasons that a properly researched trading strategy helps are its verifiability, quantifiability, consistency, and objectivity.
