There are two types of binary options.
The first type us the one you usually see advertised. The are only available from companies that are not allowed in the United States or (other countries with strong financial regulations) because they are at best, gambling and at worst complete scams.
With these companies open an account and send the company money. You then bet if a specific security will be above or below a certain price at a specified time in the future. if you win the bet the company (if it is honest) will pay you a set amount for every dollar you bet, such as 75 cents. If you lose the bet, you lose all the money you bet. The company determines when what the payout will be and the bet is settled. These binary options usually are very short-term, often settled in less than a day.
The second type of binary options are traded on an exchange. These are not scams, but are still high risk investments, You can, if authorized, buy or sell these options through the same brokerage you use for stock investments, You buy or sell these options from other traders so he price is determined by same auction process used to buy or sell stocks. You still bet if the price of a security will be above or below a certain value at a fixed time in the future. You can either buy or sell these options. If you buy them you will still lose the entire amount you bet if you bet wrong. If you buy them and are right you will be paid a fixed amount, for example a dollar a share. If you sell the option and lose your bet you have to pay the fixed amount. If you bet right you keep the amount the buyer paid you when you sold the option, You also may close a position before expiration by making another trade at the market price. These options usually do not expire until days, weeks or months after they are first issued.
