Although most trading platforms calculate profits and losses, used margin and useable margin, and account totals, it helps to understand how these things are calculated so that you can plan transactions and can determine what your potential profit or loss could be.
Most forex brokers allow a very high leverage ratio, or, to put it differently, have very low margin requirements. This is why profits and losses can be so great in forex trading even though the actual prices of the currencies themselves do not change all that much—certainly not like stocks. Stocks can double or triple in price, or fall to zero; currency never does. Because currency prices do not vary substantially, much lower margin requirements is less risky than it would be for stocks.
Most brokers allow a 100:1 leverage, or 1% margin. This means that you can buy or sell $100,000 worth of currency while maintaining $1,000 in your account. Mini-accounts can have leverage ratios as high as 200.
The margin in a forex account is a performance bond, the amount of equity needed to ensure that you can cover your losses. Thus, you do not buy currency with borrowed money, and no interest is charged on the 99% of the currency’s value that is not covered by margin. The margin requirement can be met not only with money, but also with profitable open positions. The equity in your account is the total amount of cash and the amount of unrealized profits in your open positions minus the losses in your open positions. Your total equity determines how much margin you have left, and if you have open positions, total equity will vary continuously as market prices change. Thus, it is never wise to use 100% of your margin for trades—otherwise, you may be subject to a margin call.
So if you buy $100,000 worth of currency, you are not depositing $1,000 and borrowing $99,000 for the purchase. The $1,000 is to cover your losses. If the equity in your account drops below the margin requirement, then you will have to deposit more money, or the broker will liquidate your positions. Thus, buying or selling short currency is like buying or selling short futures rather than stocks.
Leverage is inversely proportional to margin:
Leverage = 1/Margin = 100/Margin Percentage
Margin Percentage = 100/Leverage
To calculate the amount of margin used, multiply the size of the trade by the margin percentage. Subtracting the margin used for all trades from 100 yields the amount of margin that you have left.
To calculate the margin for a given trade:
Margin Requirement = Current Price x Units Traded x Margin
You want to buy 100,000 Euros with a current price of 1.35 USD, and your broker requires a 1% margin.
Required Margin = 100,000 x 1.35 x 0.01 = $1,350.00 USD.
In most cases, a pip is equal to .01% of the quote currency, thus, 10,000 pips = 1 unit of currency. In USD, 100 pips = 1 penny, and 10,000 pips = $1. A well known exception is for the Japanese yen (JPY) in which a pip is worth 1% of the yen, because the yen has little value compared to other currencies. Since there are about 120 yen to 1 USD, a pip in USD is close in value to a pip in JPY. (See Currency Quotes; Pips; Bid/Ask Quotes; Cross Currency Quotes for an introduction.)
Because the quote currency of a currency pair is the quoted price (hence, the name), the value of the pip is in the quote currency. So, for instance, for EUR/USD, the pip is equal to 0.0001 USD, but for USD/EUR, the pip is equal to 0.0001 Euro. If the conversion rate for Euros to dollars is 1.35, then a Euro pip = 0.000135 dollars.
To calculate your profits and losses in pips to your native currency, you must convert the pip value to your native currency. The following calculations will be shown using USD as an example.
When you close a trade, the profit or loss is initially expressed in the pip value of the quoted currency. To determine the total profit or loss, you must multiply the pip difference between the open price and closing price by the number of units of currency traded. This yields the total pip difference between the opening and closing transaction.
If the pip value is USD, then the profit or loss is expressed in USD, but if USD is the base currency, then the pip value must be converted to USD, which can be found by dividing the total pip profit or loss by the conversion rate.
You buy 10,000 Canadian dollars with USD, with conversion rate USD/CAD = 1.100. Subsequently, you sell your Canadian dollars for 1.1200, yielding a profit of 200 pips in Canadian dollars. Because USD is the base currency, you can get the value in USD by dividing the value by the exit price of 1.12.
10,000 CAD x 200 pips = 2,000,000 pips total. Since 2,000,000 = 200 Canadian dollars, your profit in USD is 200/1.12 = 178.57 USD.
For a cross pair not involving USD, the pip value must be converted by the rate that was applicable at the time of the closing transaction. To find that rate, you would look at the quote for the USD/pip currency pair, then multiply the pip value by this rate, or if you only have the quote for the pip currency/USD, then you divide by the rate.
You buy 100,000 units of EUR/JPY = 164.09 and sell when EUR/JPY = 164.10, and USD/JPY = 121.35.
Profit in JPY pips = 164.10 – 164.09 = .01 yen = 1 pip (Remember the yen exception: 1 JPY pip = .01 yen.)
Total Profit in JPY pips = 1 x 100,000 = 100,000 pips.
Total Profit in Yen = 100,000 pips/100 = 1,000 Yen
Because you only have the quote for USD/JPY = 121.35, to get profit in USD, you divide by the quote currency’s conversion rate:
Total Profit in USD = 1,000/121.35 = 8.24 USD.
