If you are a rookie trader, you may find yourself asking questions such as 'what is leverage in Forex trading?' and 'how can it be useful?' This article will provide you with answers to these types of questions, together with, a detailed overview of Forex leveraging, its advantages and disadvantages, and a list of possible applications and restrictions.
This is why many traders decide to employ gearing, also known as financial leverage, in their trading - so that the size of the trading position and profits could be higher. Let's assume a trader with 1,000 USD on their account balance wants to trade big and their broker is supplying a leverage of 1:500. This way a trader can open a position that is as large as 5 lots, when it is denominated in USD. In other words, 1,000 USD * 500 (the leverage), would equal a maximum size of 500,000 USD for the position. The trader can actually request their orders of 500 times the size of his deposit to be filled.
The carry trade opportunity was also seen in USD/JPY in 2005. Between January and December of that year, the currency rallied from 102 to a high of 121.40 before ending at 117.80. This is equal to an appreciation from low to high of 19%, which was far more attractive than the 2.9% return in the S&P 500 during that same year. In addition, at the time, the interest rate spread between the U.S. dollar and the Japanese yen averaged around 3.25%. Unleveraged, this means that a trader could have earned as much as 22.25% over the course of the year. Introduce 10:1 leverage, and that could be as much as 220% gain.
Leverage simply allows traders to control larger positions with a smaller amount of actual trading funds. In the case of 50:1 leverage (or 2% margin required), for example, $1 in a trading account can control a position worth $50. As a result, leveraged trading can be a "double-edged sword" in that both potential profits as well as potential losses are magnified according to the degree of leverage used. 

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. 
Currencies are traded on the Foreign Exchange market, also known as Forex. This is a decentralized market that spans the globe and is considered the largest by trading volume and the most liquid worldwide. Exchange rates fluctuate continuously due to the ever changing market forces of supply and demand. Forex traders buy a currency pair if they think the exchange rate will rise and sell it if they think the opposite will happen. The Forex market remains open around the world for 24 hours a day with the exception of weekends.
