In one sentence, describe what the following article is about: Binary options are enormously popular in Europe and are extensively traded in major European exchanges, like EUREX. In the United States there are a few places where binary options can be traded:  The Chicago Board of Trade (CBOT) offers binary options trading on the Target Fed Funds Rate. To trade these contracts, traders must be members of the exchange. Other investors must trade through a member. The value of each contract is $1,000. Nadex is a U.S.-regulated binary options exchange. Nadex offers a range of expiration opportunities (hourly, daily, weekly) that allow traders to take a position based on market developments. The choice is vast with over 2,400 binary option contracts each day. These range from popular currency pairs (such as Great Britain Pound/USD) to key commodities like gold and oil. Members' funds are held in a segregated U.S. bank account  in accordance with Commodities Futures Trading Commission (CFTC) regulations, adding an extra layer of security. Binary options brokers should not charge any per-trade fees, nor should they collect any commissions. You should also understand the percentage of time would you have to be correct in order to profit from the binary option you are considering.  For example, if you were buying into options at for $40 each and each one has a settlement value of $100 if you are correct, you would need to be correct 2 out of 5 times to break even, and more often than that to turn a profit (cost: 5*$40=$200, return: 2*$100=$200). Screen several brokers before making a selection. Each broker is going to provide his or her own trading platform, contract terms, assets, return rates, and educational resources. Each of these elements can have an impact on overall earnings potential. It is extremely rare and difficult to outperform the market consistently. That means that options traders typically have to engage in many transactions in order to wind up with a profitable position. Consequently, a trader faces the possibility of high transaction costs and lower profits. 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)?  If they are significantly different, the buyer would be forced into the unusual position of having to predict the magnitude as well as the direction of a price movement.
Summary: Learn where binary options are traded. Check for transaction costs and potential profits. Know the transaction costs ahead of time. Understand the trading terms for each deal.

Problem: Article: Most of us enjoyed reading a specific book or series of books as children. Re-read your favorite to feel like a kid again.  For a more authentic and affordable experience, check out a book from the public library instead of ordering it online or shopping in a store. Re-create the times you stayed up late reading under the covers with a flashlight. While automobiles present a convenient way to get from point A to point B, they tend to make you feel more like a grown up. Instead, try riding a bike so you can remember how it felt to coast down a hill with the wind in your face. Don’t worry about heading to a specific destination. Most kids just enjoy riding for the fun of it. Research and rock out to a top 40 playlist from your youth.  Dig out your old CDs, cassettes, 8-tracks, or vinyl to relive pleasure of music before the Internet. If you discarded all your old media, many Internet radio services already have playlists built around certain decades or years, so it shouldn’t be difficult to re-create the soundtrack of your childhood. Most children don’t have the inhibitions that adults do, so sing and dance the way you used to. As an adult, you probably agonize over what you eat, but as a kid, you likely had a favorite treat or food that was less than healthy. You don’t have to make a regular habit out of this, but enjoying some of these treats might help you feel like a kid again:  Popsicles or ice cream. Pizza. Candy. A specific type of soda or fruit punch. Cotton candy. Recapture that youthful feeling and relive your glory days by visiting some of your childhood haunts. Here are a few locations to help get you started:  Fairs, the circus, or amusement parks. Mini-golf courses. Arcades. Go-kart tracks. Water parks. Zoos. Toy stores. Skating rinks. Playgrounds. Kids play with a sense of abandon and don’t worry about making a mess. Put on clothes you don’t mind getting dirty, and splash around in puddles or make some mud pies. The pride of accomplishment that comes from climbing a tree and the sense of exhilaration that you feel when sitting up high will take you back to a simpler time.  Remember, you’re probably bigger now than you were the last time you attempted this, and make sure you reach for sturdy branches. If you don’t care for heights, don’t despair. Try playing, reading, or enjoying a picnic below the tree. Choose what you want to wear without worrying about whether it matches perfectly or conveys the right message to your peers or colleagues. If you work in an environment with a strict dress code, it might be best to save this activity for your day off. If you are fortunate enough to live in an area with an ice-cream truck, take advantage of this opportunity usually reserved for kids. Ice-cream from the truck often tastes better than the kind you get at the store, and it can be hard to find some of these childhood treats anywhere else. Many people spend their childhoods swinging, sliding, and climbing a jungle gym at the playground. Visiting these places will remind you how it feels to play like a kid.  If you’re feeling adventurous, try tackling the monkey bars. Much of this equipment is designed to hold the weight of children. Test it out carefully before using, because nothing makes you feel more like an adult than filling out emergency-room paperwork. Although you might not consider yourself an artistic person, spending a little time engaged in creative activities will help you relax.  You don’t have to pick an elaborate craft or activity. Use modeling clay, a coloring book, or even paint by numbers for a simple but fun experience. Art projects make great rainy day activity. Think about some of the games you enjoyed as a child, and recruit some friends or family members to join you. Here are a few ideas to get you started:  Hopscotch. Four square. Tag or capture the flag. Dodgeball. Hide-and-seek. Jumping rope. Board games. Team sports. When was the last time you just enjoyed being around your friends? Get your group together without a specific agenda, or enjoy some of the activities you used to love as kids.  Organize a slumber party. Play video games. Watch scary movies. Play truth-or-dare. Make a pact that you won't talk about work or adult responsibilities.
