What is Trade?

When we say what is  trade? The simple answer is MONEY.
Because you are not buying anything physically.
Think you buying a currency as buying a share in a particular country, you want to  buying a stocks of a company in your country. The price of the currency is a directly reflection of what the market thinks about the current and future health your country economy.
When you buy a US Dollar  you are basically buying a "share" in the US economy. After You sawing that the US economy is doing well, and will even get better as time goes. Once you sell those "shares" to the market and  you will end your trade with a profit.
In general, the exchange rate of a currency different from other currencies is a reflection of the condition of that country's economy, compared to other countries economies.
