What Happens Now?
Let's continue with the same example:

First of all, you have ensured the exchange rate of 1.0700 for the date 60 days from today. Nothing can change that.
Let's examine what happens when the deal ends, using various exchange rates:

[1] The EUR/USD exchange rate reached 1.1000 sometime during the pre-set period.
In this case, the deal has already been terminated at your pre-defined STOP-LOSS rate of 1.0900. You have lost 200 EURO, the amount you were willing to risk.
[2] The EUR/USD exchange rate at the specified date is 1.0800. In this case you lose just EUR 100.
[3] The EUR/USD exchange rate at the specified date is 1.0200. You have made a profit of EUR 500!!!

Notes:
[1] The example provided is for illustrative purposes only.

[2] In real life, the exchange rates change automatically and continuously. Whenever you wish to make a deal using a specific rate appearing on the screen, after pressing the "GET RATE" key it will be "frozen" for you, allowing you a few seconds to accept or reject it.
