"...Forex dealers can set their own minimum account sizes, so you will have to ask the dealer how much money you must put up to begin trading. Most dealers will also require you to have a certain amount of money in your account for each transaction. This security deposit, sometimes called margin, is a percentage of the transaction value and may be different for different currencies. A security deposit acts as a performance bond and is not a down payment or partial payment for the transaction.
Dealers who are regulated by NFA are required to calculate and collect security deposits that equal or exceed the percentage set by NFA rules. Although the percentage of the security deposit remains constant, the dollar amount of the security deposit will change with changes in the value of the currency being traded.
The formula for calculating the security deposit is:
Current price of base currency X transaction size X security deposit % = security deposit requirement given in quote currency
Returning to our Euro example with an initial price of $1.2178 for each Euro and a transaction size of 100,000 Euros, a 1% security deposit would be $1,217.80.
$1.2178 X 100,000 X .01 = $1,217.80
Security deposits allow customers to control transactions with a value many times larger than the funds in their accounts. In this example, $1,217.80 would control $121,780 worth of Euros.
Value of Euros = $1.2178 X 100,000 = $121,780
This ability to control a large amount of one currency, in this case the Euro, using a very small percentage of its value is called leverage or gearing. In our example, the leverage is 100:1 because the security deposit controls Euros worth 100 times the amount of the deposit.
Since leverage allows you to control large amounts of currency for a very small amount, it magnifies the percentage amount of your profits and losses. A profit or loss of $1,217.80 on the Euro trans- action is 1% of the full price (with leverage of 1:1) but is 100% of the 1% security deposit. The dollar amount of profits and losses does not change with leverage, however. The profit or loss is $1,217.80 whether the leverage is 100:1 or 25:1 or 1:1.
