If, on the other hand, you believe that the euro will weaken against the dollar, you'll want to sell EURUSD.

• You sell euro

 

We quote EURUSD at a Bid price of 0.9875 and Ask price of 0.9880 and you decide to sell euro 100,000 at a Bid price of 0.9875.

• The market moves in your favour

 

The euro weakens against the dollar and the EURUSD is now quoted at bid 0.9744 and ask 0.9749.

• Now you buy back your euro

 

You buy EUR at an ask price of 0.9749.

• Your profit/loss is then

 

Sell price-buy price x size of trade
(0.9875 minus 0.9749) multiplied by 100.000 = USD 1260 Profit

Remember that trading EUR 100,000 as we have done in our examples, does not mean that you have to put up euro 100,000 yourself. On a 2% margin means that you have to deposit 2.0% of euro 100,000, which is euro 2,000 on margin as a guarantee for the future performance of your position.
