How do I calculate profit and loss?

Let’s buy U.S. dollars and sell Swiss francs.

1. The rate you are quoted is 1.4525 / 1.4530. Because you are buying U.S. dollars you will be working on the “ASK” price of 1.4530, the rate at which traders are prepared to sell.
2. So you buy 1 standard lot (100,000 units) at 1.4530.
3. A few hours later, the price moves to 1.4550 and you decide to close your trade.
4. The new quote for USD/CHF is 1.4550 / 1.4555. Since you initially bought to open the trade, to close the trade, you now must sell in order to close the trade so you must take the “BID” price of 1.4550. The price that traders are prepared to buy at.
5. The difference between 1.4530 and 1.4550 is .0020 or 20 pips.
6. Using our formula from before, we now have (.0001/1.4550) x 100,000 = $6.87 per pip x 20 pips = $137.40

Bid/Ask Spread

Remember, when you enter or exit a trade, you are subject to the spread in the bid/ask quote.

When you buy a currency, you will use the offer or ASK price. 

When you sell, you will use the BID price.
