The CFTC and SEC have received numerous complaints of fraud associated with websites that offer an opportunity to buy or trade binary options through Internet-based trading platforms. The complaints fall into at least three categories: refusal to credit customer accounts or reimburse funds to customers; identity theft; and manipulation of software to generate losing trades.
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).
