I am transferring money from an AED account in Dubai to my Irish euro account using an Irish currency company. I am registered on their site and I am using live trades which is updated every 3 seconds. The rates vary so much in a short period of time.
Example 100,000 aed = 20,100 euro at the moment tomorrow morning it could be worth 19,900 euro and by evening 20,100. How could one buy and sell a currency in short periods of time ?
