Forex trading is the trading of money and currencies around the world. Most of the countries of the world participate in the forex trading market where money is bought and sold based on the value of that currency at the time. Because some coins are not worth much, they are not traded much, because the value of a coin is greater, more brokers and bankers will decide to invest in this market at this time.
Forex trading happens every single day and with nearly $2 trillion being moved around each day, that's a huge amount. Think about how many millions you need to total a trillion, and then keep in mind that this happens on a daily basis - if you want to be involved with where the money is, then forex trading is the "stage" where that money is. Exchange hands every day.
The currencies traded in the foreign exchange markets will be the currencies of all countries of the world. Each currency has its own three letter code that represents that country and the currency in which it is traded. For example, the Japanese yen is the yen and the US dollar is the US dollar. The pound sterling is the pound sterling and the euro is the euro. You can trade many currencies in one day, or you can trade a different currency every day. Most trades are done through a broker, or one for which each company charges a fee. So you must be sure of the trade you are taking before you place a lot of trades that require high fees.
Exchanges between markets and countries will take place every day. Some of the most intense transactions are between the Euro and the US dollar, then between the US dollar and the Japanese yen, and the other most common transactions are between the British pound and the US dollar. Trades take place all day and all night and are for different markets. While one country opens trading for the day, another closes. Time zones around the world affect how trading is conducted and when the markets are open.
As you trade from one market to another and merge one currency into another, you will find that symbols are used to explain transactions. All trades look like this: EURzzz / USDzzz, where zzz is the percentages of the trade multiplied by the percentage of the transaction. Other examples might look like AUSzzz/USD etc. When you read and review your currency data and information online, you will understand everything better if you remember these codes for the respective currencies.
