Arbitrage trading also happens in sportsbook betting, in merchandise bulk purchases, and in the currency exchange. Online sportsbooks create odds that allow the bettor to bet on possible wins while making profits on the bookie's side. If you're a merchandise trader, you simply acquire bulk products at a discounted price from the factory and sell them to clients who are willing to pay you if you give them a lower price than normal. If you're a currency trader, you would have to look for the exchange rates of currencies in several countries and have the dollar and the euro, for instance, exchanged for a profit.
