Trading Scenario – Trading Falling Prices 
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.
