No matter which binary options you trade--Nadex options or traditional binary options--"position size" is important. Your position size is how much you risk on a single trade. How much you risk shouldn't be random, nor based on how convinced you are a specific trade will work out in your favor. View position size as a formula, and use it for every trade. 

Binary options come in many different flavors, such as “one–touch” options where a trader can anticipate that the price will touch a level. There also are range options, where a trader can take a position on whether the price will stay within a specific range. On some platforms, traders can select their own target strike prices. There are also 60-second expiration options. These are the most difficult to end up in-the-money because the price behavior in these durations is very volatile. Many firms offer binary options that basically are set, which lock in a position until expiration, although some firms allow closing the position before expiration. Yes, binary options are exciting, offering within minutes the result of a win or loss.
Most binary options brokers will feature a graph on each asset listed on their platform. In the case of Gold, the graph provided will have a line to indicate the movement of gold prices over time. From the provided graph, you can see how the price of Gold has been changing over time. As such, you can decide on the probable direction that the price will move in the near future. It is on this basis that you make your prediction on whether the price of Gold will rise or fall in the near future.

But above all, look for having a money management system in place. Not any money management system works, especially when trading binary options. Risk diversification is key. Try to split the risk among various asset classes. Split it when it comes to the amount traded, the financial products, the expiration dates, and the technical or fundamental reason for taking a trade.


Say you invest $100 in the call that expires in 30 minutes. The S&P 500 price at expiration determines whether you make or lose money. The price at expiration may be the last quoted price, or the (bid+ask)/2. Each binary options broker outlines their own expiration price rules. In this case, assume the last quote on the S&P 500 before expiration was 1,802. Therefore, you make a $70 profit (or 70% of $100) and maintain your original $100 investment. If the price finished below 1,800, you would lose your original $100 investment. If the price expires exactly on the strike price, it is common for the trader to receive her/his money back with no profit or loss, although brokers may have different rules. The profit and/or original investment is automatically added to the trader's account when the position is closed.
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]
