To see the most recent list of exchanges that are designated as contract markets, check the CFTC website.  There currently are only three designated contract markets offering binary options in the U.S.: Cantor Exchange LP; Chicago Mercantile Exchange, Inc.; and the North American Derivatives Exchange, Inc.  All other entities offering binary options that are commodity options transactions are doing so illegally.
Chance, your broker, and your trading system certainly all have an impact on whether you win or lose, but they are not the whole of it, and the most important factor in the equation is always the trader. When you take responsibility for your trading career, you empower yourself instead of leaving yourself at the mercy of chance, and that gives you the best chance of actually achieving your trading goals!
Learn how a contract price is determined. The offer price of a binary options contract is roughly equal to the market's perception of the probability of the event happening. The price of a binary option is presented as a bid/offer price that shows the bid (sell) price first and offer (buy) price second, for example, 3/96, which represents a bid price of $3 and an offer price of $96.

When you're starting out, calculate your ideal position size for each trade. Even when actively day trading there is time before each trade to quickly determine how much to wager based on your percentage risk tolerance and the trade you are considering. This repetition will serve you well, and when you are losing money the dollar amount you can risk will drop (as the account value drops) and when you are winning the dollar amount you can risk will increase (as the account value increases). Note that your percentage at risk doesn't change, but as your account value fluctuates the dollar amount that percentage represents does change.

Know when to get out of a position. An intuitive trader acts promptly when he feels that his binary contract is going to end out-of-the-money at expiration. Example: You have a $75.00 silver contract that you feel is not going to expire in-the-money. Instead of holding it until the expiration date, selling it at $30.00 and neutralizing your open interest will help you manage the loss (by losing $45 instead of $75 once it was confirmed to expire out-of-the-money).

Cold Calls. Professional brokers will not make cold calls – they do not market themselves in that way. Cold calls will often be from unregulated brokers interested only in getting an initial deposit. Proceed extremely carefully if joining a company that got in contact this way. This would include email contact as well – any form of contact out of the blue.
It is up to you to ultimately determine which type of asset is best for you. You first need to evaluate your level of experience. Do you have experience with the Forex market and are looking for a new and more profitable way to trade? If this applies to you, you will easily be able to apply your strategies to the binary options market. Or does your expertise come from day trading? Are you looking to rid yourself of some of the risk involved in day trading? Then binary options can certainly benefit you as you have the ability to focus on those assets with which you are most familiar.
Binary options are often considered a form of gambling rather than investment because of their negative cumulative payout (the brokers have an edge over the investor) and because they are advertised as requiring little or no knowledge of the markets. Gordon Pape, writing in in 2010, called binary options websites "gambling sites, pure and simple", and said "this sort of thing can quickly become addictive... no one, no matter how knowledgeable, can consistently predict what a stock or commodity will do within a short time frame".[23]
