The use of leverage basically exacerbates any sort of market movements. As easily as it increases profits, it can just as quickly cause large losses. However, these losses can be capped through the use of stops. Furthermore, almost all forex brokers offer the protection of a margin watcher – a piece of software that watches your position 24 hours a day, five days per week and automatically liquidates it once margin requirements are breached. This process ensures that your account will never post a negative balance and your risk will be limited to the amount of money in your account.
When a trader decides to trade in the forex market, he or she must first open a margin account with a forex broker. Usually, the amount of leverage provided is either 50:1, 100:1 or 200:1, depending on the broker and the size of the position that the investor is trading. What does this mean? A 50:1 leverage ratio means that the minimum margin requirement for the trader is 1/50 = 2%. A 100:1 ratio means that the trader is required to have at least 1/100 = 1% of the total value of trade available as cash in the trading account, and so on. Standard trading is done on 100,000 units of currency, so for a trade of this size, the leverage provided is usually 50:1 or 100:1. Leverage of 200:1 is usually used for positions of $50,000 or less.

Between 2003 and the end of 2004, the AUD/USD currency pair offered a positive yield spread of 2.5%. Although this may seem very small, the return would become 25% with the use of 10:1 leverage. During that same time, the Australian dollar also rallied from 56 cents to close at 80 cents against the U.S. dollar, which represented a 42% appreciation in the currency pair. This means that if you were in this trade – and many hedge funds at the time were – you would have not only earned the positive yield, but you would have also seen tremendous capital gains in your underlying investment.

From this we can see that the Forex leverage ratio strongly depends on the strategy that is going to be used. To give you a better overview, scalpers and breakout traders try to use as high a leverage as possible, as they usually look for quick trades. Positional traders often trade with low leverage or none at all. A desired leverage for a positional trader usually starts at 5:1 and goes up to about 20:1.

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.
Many traders define leverage as a credit line that a broker provides to their client. This isn't exactly true, as leverage does not have the features that are issued together with credit. First of all, when you are trading with leverage you are not expected to pay any credit back. You are simply obliged to close your position, or keep it open before it is closed by the margin call. In other words, there is no particular deadline for settling your leverage boost provided by the broker.

In every foreign exchange transaction, you are simultaneously buying one currency and selling another. In effect, you are using the proceeds from the currency you sold to purchase the currency you are buying. Furthermore, every currency in the world comes attached with an interest rate set by the central bank of that currency's country. You are obligated to pay the interest on the currency that you have sold, but you also have the privilege of earning interest on the currency that you have bought. For example, let’s look at the New Zealand dollar/Japanese yen pair (NZD/JPY). Let’s assume that New Zealand has an interest rate of 8% and that Japan has an interest rate of 0.5% In the currency market, interest rates are calculated in basis points. A basis point is simply 1/100th of 1%. So, New Zealand rates are 800 basis points and Japanese rates are 50 basis points. If you decide to go long NZD/JPY you will earn 8% in annualized interest, but have to pay 0.5% for a net return of 7.5%, or 750 basis points.
