Talk about a great word to use at cocktail parties (especially if you can say it with a vaguely Euro posh accent). Arbitrage is the business of finding something for cheap and then turning around and selling it for more to another customer, keeping the profits...basically, it's the art of taking advantage of the spaces that open up within markets.
Let's say that the kid down the block is selling lemonade for $0.50 a glass, but the local construction workers are willing to pay $1.00 a glass. You buy from the kid, upsell to the construction guys, and pocket the $0.50 difference each time.
Back in the good old days, arbitrage was considered easy money. Thanks to online and electronic trading, though, it's gotten a lot less profitable. For one thing, any 14-year-old with an Internet connection can find a cheaper deal online, so there's less opportunity. There's also less need for the middle man. The construction workers probably have an app on their phone that lets them find the cheapest lemonade around, meaning they don't need your help.
Another current problem with arbitrage is the commissions and other costs and fees. Every trade you make online is going to cost you something, so there needs to be a big difference between buy and sell prices for you to make a profit.
