In order to determine which is the fixed currency when neither currency is on the above list (i.e.both are "other"), market convention is to use the fixed currency which gives an exchange rate greater than 1.000.
Forex contracts involve the right to buy or sell a certain amount of a foreign currency at a fixed price in U. It is extremely rare that individual traders actually see the foreign currency.
Instead, they typically close out their buy or sell commitments and calculate net gains or losses based on price changes in that currency relative to the dollar over time.
The authors suggest a new hybrid neural network which is a combination of the standard RBF neural network, a genetic algorithm, and a moving average.
The moving average is supposed to enhance the outputs of the network using the error part of the original neural network.
The real exchange rate (RER) is the purchasing power of a currency relative to another at current exchange rates and prices.
It is the ratio of the number of units of a given country's currency necessary to buy a market basket of goods in the other country, after acquiring the other country's currency in the foreign exchange market, to the number of units of the given country's currency that would be necessary to buy that market basket directly in the given country.
This is the exchange rate (expressed as dollars per euro) times the relative price of the two currencies in terms of their ability to purchase units of the market basket (euros per goods unit divided by dollars per goods unit).
If all goods were freely tradable, and foreign and domestic residents purchased identical baskets of goods, purchasing power parity (PPP) would hold for the exchange rate and GDP deflators (price levels) of the two countries, and the real exchange rate would always equal 1.
Even if a company expects to be paid in its own currency, it must assess the risk that the buyer may not be able to pay the full amount due to currency fluctuations.
