Trading leverage or leveraged trading allows you to control much larger amounts in a trade, with a minimal deposit in your account. Leveraged trading is also known as margin trading. You can open up a small account with a brokerage, and then essentially borrow money from the broker to open a large position. This allows traders to magnify the amount of profits earned.

Currency values never remain stationary, and it is this dynamic that gave birth to one of the most popular trading strategies of all time, the carry trade. Carry traders hope to earn not only the interest rate differential between the two currencies (discussed above), but also look for their positions to appreciate in value. There have been plenty of opportunities for big profits in the past. Let’s take a look at some historical examples. 
A single pound on Monday could get you 1.19 euros. On Tuesday, 1.20 euros. This tiny change may not seem like a big deal. But think of it on a bigger scale. A large international company may need to pay overseas employees. Imagine what that could do to the bottom line if, like in the example above, simply exchanging one currency for another costs you more depending on when you do it? These few pennies add up quickly. In both cases, you—as a traveler or a business owner—may want to hold your money until the forex exchange rate is more favorable.
To trade $100,000 of currency, with a margin of 1%, an investor will only have to deposit $1,000 into her or his margin account. The leverage provided on a trade like this is 100:1. Leverage of this size is significantly larger than the 2:1 leverage commonly provided on equities and the 15:1 leverage provided in the futures market. Although 100:1 leverage may seem extremely risky, the risk is significantly less when you consider that currency prices usually change by less than 1% during intraday trading (trading within one day). If currencies fluctuated as much as equities, brokers would not be able to provide as much leverage.
