In an open economy, imports are positively related to income and production. When the gross domestic product is rapidly increasing, imports tend to grow faster. Moreover, the choice between foreign and domestic goods respond to relative prices of the two. For both the volume and value of imports depend on the relative prices of domestic and foreign goods.
The exchange rate affects foreign trade, so that when you raise the exchange rate of a country, raise prices of imported goods, while exports become cheaper for foreigners. As a result, the country is more competitive in world markets and net exports increase. Changes in exchange rates can profoundly affect production, employment and inflation. All these effects make the exchange rate is increasingly important for all countries. The same applies for online currency trading.
Exports are the twin sister of imports: our exports are imports from the rest of the world.
