With a
US$5,000 balance in your margin account, you decide that the
US Dollar (USD) is undervalued against the Swiss Franc
(CHF).
To
execute this strategy, you must buy Dollars (simultaneously
selling Francs), and then wait for the exchange rate to
rise.
The
current bid/ask price for USD/CHF is 1.6322/1.6327 (meaning
you can buy $1 US for 1.6327 Swiss Francs or sell $1 US for
1.6322)
Your
available leverage is 100:1 or 1%. You execute the trade,
buying a one lot: buying 100,000 US dollars and selling
163,270 Swiss Francs.
At 100:1
leverage, your initial margin deposit for this trade is
$1,000. Your account balance is now $4000.
As you
expected, USD/CHF rises to 1.6435/40. You can now sell $1 US
for 1.6435 Francs or buy $1 US for 1.6440 Francs. Since
you're long dollars (and are short francs), you must now
sell dollars and buy back the francs to realize any profit.
You close
out the position, selling one lot (selling 100,000 US dollar
and receiving 164,350 CHF) Since you originally sold (paid)
163,270 CHF, your profit is 1080 CHF.
To
calculate your P&L in terms of US dollars, simply divide
1080 by the current USD/CHF rate of 1.6435. Your profit on
this trade is $657.13
