The bottom line is that you want to pick carry trades that benefit not only from a positive and growing yield, but that also have the potential to appreciate in value. This is important because just as currency appreciation can increase the value of your carry trade earnings, currency depreciation can erase all of your carry trade gains – and then some. 

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.

Although the ability to earn significant profits by using leverage is substantial, leverage can also work against investors. For example, if the currency underlying one of your trades moves in the opposite direction of what you believed would happen, leverage will greatly amplify the potential losses. To avoid a catastrophe, forex traders usually implement a strict trading style that includes the use of stop orders and limit orders designed to control potential losses.


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.
