The primary purpose of the Foreign Exchange (Forex) is to assist international trade and investment, by allowing businesses to convert one currency to another currency. For example, it permits a US business to import British goods and pay Pound Sterling, even though the business's income is in US dollars. It also supports speculation, and facilitates the carry trade, in which investors borrow low-yielding currencies and lend (invest in) high-yielding currencies, and which (it has been claimed) may lead to loss of competitiveness in some countries.

So, What Is Forex again?

The Foreign Exchange market is the "place" where currencies are traded. Knowing what is Forex is important to most people around the world. If you are living in the U.S. and want to buy cheese from France, either you or the company that you buy the cheese from has to pay the French for the cheese in Euros (EUR). This means that the U.S. importer would have to exchange the equivalent value of U.S. dollars (USD) into Euros.
The need to exchange currencies is the primary reason why the Forex market is the largest, most liquid financial market in the world. It dwarfs other markets in size, even the stock market, with an average traded value of around U.S. $3.98 tillion per day.
One unique aspect of this international market is that there is no central marketplace for Foreign Exchange. Rather, currency trading is conducted electronically Over-The-Counter (OTC), which means that all transactions occur via computer networks between traders around the world, rather than on one centralized exchange. The market is open 24 hours a day, five and a half days a week, and currencies are traded worldwide in the major financial centers of London, New York, Tokyo, Zurich, Frankfurt, Hong Kong, Singapore, Paris and Sydney - across almost every time zone. This means that when the trading day in the U.S. ends, the Forex market begins a new in Tokyo

What is the spot market?

What is Forex Spot is also a question traders care about. , determined by supply and demand, the price of spot forex is a reflection of current forex interest rates, economic performance and sentiment towards ongoing political situations. When a deal is finalized, this is known as a "spot deal". It is a bilateral transaction by which one party delivers an agreed-upon currency amount to the counter party and receives a specified amount of another currency at the agreed-upon exchange rate value. After a position is closed, the settlement is in cash.
What is Forex Quote
One of the biggest sources of confusion for those new to the currency market is the standard for quoting currencies. When a currency is quoted, it is done in relation to another currency, so that the value of one is reflected through the value of another. Therefore, if you are trying to determine the exchange rate between the U.S. dollar (USD) and the Japanese yen (JPY), the Forex quote would look like this: USD/JPY = 76.50
This is referred to as a currency pair. The currency to the left of the slash is the base currency, while the currency on the right is called the quote or counter currency. The base currency (in this case, the U.S. dollar) is always equal to one unit (in this case, US$1), and what is forex quote means what that one base unit is equivalent to in the other currency. The quote means that US$1 = 76.50 Japanese yen. In other words, US$1 can buy 769.50 Japanese yen. The Forex quote includes the currency abbreviations for the currencies in question. There are two ways to quote a currency pair, either directly or indirectly. Also, Cross Currency quote is given without the U.S. dollar as one of its components.
