One of the most unique features of the forex market is that it is comprised of a global network of financial centers that transact 24 hours a day, closing only on the weekends. As one major forex hub closes, another hub in a different part of the world remains open for business. This increases the liquidity available in currency markets, which adds to its appeal as the largest asset class available to investors.
Money transfer companies/remittance companies perform high-volume low-value transfers generally by economic migrants back to their home country. In 2007, the Aite Group estimated that there were $369 billion of remittances (an increase of 8% on the previous year). The four largest foreign markets (India, China, Mexico, and the Philippines) receive $95 billion. The largest and best-known provider is Western Union with 345,000 agents globally, followed by UAE Exchange.[citation needed] Bureaux de change or currency transfer companies provide low-value foreign exchange services for travelers. These are typically located at airports and stations or at tourist locations and allow physical notes to be exchanged from one currency to another. They access foreign exchange markets via banks or non-bank foreign exchange companies.
Hedge funds – Somewhere around 70 to 90% of all foreign exchange transactions are speculative in nature. This means, the person or institutions that bought or sold the currency has no plan of actually taking delivery of the currency; instead, the transaction was executed with sole intention of speculating on the price movement of that particular currency. Retail speculators (you and I) are small cheese compared to the big hedge funds that control and speculate with billions of dollars of equity each day in the currency markets.
Major Currency — currencies from the world’s most developed economies including Europe, Japan, Canada, and Australia — represent the most heavily traded and liquid currency markets for any forex trader. A major currency pair is created when one of these currencies is traded against the U.S. dollar. Examples include Euro vs. the U.S. Dollar (EUR/USD) and the U.S. Dollar vs. the Canadian Dollar (USD/CAD). Their availability on a forex brokerage is essential.
Forex, also known as foreign exchange, FX or currency trading, is a decentralized global market where all the world's currencies trade. The forex market is the largest, most liquid market in the world with an average daily trading volume exceeding $5 trillion. All the world's combined stock markets don't even come close to this. But what does that mean to you? Take a closer look at forex trading and you may find some exciting trading opportunities unavailable with other investments.

More specifically, the spot market is where currencies are bought and sold according to the current price. That price, determined by supply and demand, is a reflection of many things, including current interest rates, economic performance, sentiment towards ongoing political situations (both locally and internationally), as well as the perception of the future performance of one currency against another. 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. Although the spot market is commonly known as one that deals with transactions in the present (rather than the future), these trades actually take two days for settlement.
