Nadex binary options don't have rebates on losing trades, but if you buy an option at 50, and it drops to 30, you can sell it for a partial loss, instead of waiting for it to drop to 0 (or move above 50, which would produce a profit). Ultimately though, at expiry, the Nadex option will be worth 100 or 0. Therefore, when determining your risk you must assume the worst case scenario. 
Successful traders research their assets well, keeping up to date with any news that is likely to affect their asset price and keep an eye on an Economic Calendar, checking what events are coming up that may cause the asset price to rise or fall. In addition, they use proven strategies that work for them. Trading without research or reliable binary options trading strategy is a sure way to lose more trades than you win and your broker will love you!

Understand the trading terms for each deal. How different are the terms (for instance, "strike price") on one side of the trade (above strike price) compared to the reverse side (below strike price)?

It might shock investors to know that binary options are in fact, not categorized as “financial options” under the U.K’s Financial Services Act, but instead they are regulated under the U.K. Gaming Commission where binary option trades are actually classified as “bets.” In the U.K. gambling debts are known as “debts of honor” and are not enforceable in the court system.
Pape observed that binary options are poor from a gambling standpoint as well because of the excessive "house edge". One online binary options site paid $71 for each successful $100 trade. "If you lose, you get back $15. Let's say you make 1,000 "trades" and win 545 of them. Your profit is $38,695. But your 455 losses will cost you $38,675. In other words, you must win 54.5% of the time just to break even".[23]
