Decide your position. Evaluate the current market conditions surrounding your chosen stocks or other asset and determine whether the price is more likely to rise or fall. If your insight is correct on the expiration date, your payoff is the settlement value as stated in your original contract. The return rate on each winning trade is established by the broker and made known ahead of time.

These complaints typically involve customers who have deposited money into their binary options trading account and who are then encouraged by “brokers” over the telephone to deposit additional funds into the customer account.  When customers later attempt to withdraw their original deposit or the return they have been promised, the trading platforms allegedly cancel customers’ withdrawal requests, refuse to credit their accounts, or ignore their telephone calls and emails.
A binary option is a financial exotic option in which the payoff is either some fixed monetary amount or nothing at all.[1][2] 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).[3]
