The foreign exchange market works through financial institutions and operates on several levels. Behind the scenes, banks turn to a smaller number of financial firms known as "dealers", who are involved in large quantities of foreign exchange trading. Most foreign exchange dealers are banks, so this behind-the-scenes market is sometimes called the "interbank market" (although a few insurance companies and other kinds of financial firms are involved). Trades between foreign exchange dealers can be very large, involving hundreds of millions of dollars. Because of the sovereignty issue when involving two currencies, Forex has little (if any) supervisory entity regulating its actions.

All forex trades involve two currencies because you're betting on the value of a currency against another. Think of EUR/USD, the most-traded currency pair in the world. EUR, the first currency in the pair, is the base, and USD, the second, is the counter. When you see a price quoted on your platform, that price is how much one euro is worth in US dollars. You always see two prices because one is the buy price and one is the sell. The difference between the two is the spread. When you click buy or sell, you are buying or selling the first currency in the pair.
The series of contagious currency crises in the 1990s—in Mexico, Brazil, East Asia, and Argentina—again focused policy makers’ minds on the problems of the international monetary system. Moves, albeit limited, were made toward a new international financial architecture. Most importantly, these crises led to the establishment of the Financial Stability Forum (since 2009 the Financial Stability Board), which investigated the problems of offshore, capital flows, and hedge funds; and the G20, which attempted to broaden the international regime’s membership and thus deepen its legitimacy. In addition, there were calls for a currency transaction tax, named after Nobel Laureate James Tobin’s proposal, from many civil society nongovernmental organizations as well as some governments. The success of international monetary reform is a crucial issue for governments and their autonomy, firms and the stability of their investments, and citizens who ultimately are those who absorb these effects as they are transmitted into everyday life.

The most favorable trading time is the 8 AM to noon overlap, when both New York and London exchanges are open. These two trading centers account for more than 50% of all forex trades. On the flipside, from 5 PM to 6 PM EST, the only operation open for business is the Singapore exchange, which accounts for less than 10% of annual forex trading volume. But there an be exceptions. Political or military crises that develop during this hour, could potentially spike volatility and trading volume, making this window a favorable time to trade.

In the Forex market, currencies always trade in pairs. When you exchange US dollars for euros, there are two currencies involved. For every foreign exchange transaction, you must exchange one currency for another. This is why the forex market uses currency pairs, so you can see the cost of one currency relative to another. The EUR/USD price, for example, lets you know how many US dollars (USD) it takes to buy one euro (EUR).
The world then decided to have fixed exchange rates that resulted in the U.S. dollar being the primary reserve currency and that it would be the only currency backed by gold, this is known as the ‘Bretton Woods System’ and it happened in 1944 (I know you super excited to know that). In 1971 the U.S. declared that it would no longer exchange gold for U.S. dollars that were held in foreign reserves, this marked the end of the Bretton Woods System.
If you take a look at the FOREX quotes on your trading platform you will see that there are two prices for each currency pair. One is the price at which you can buy, referred to as the "ask price", and the other is the price at which you can sell, referred to as the "bid price". The difference between these two prices is known as the spread. The ask price is always higher than the bid price.
The profit you made on the above theoretical trade depends on how much of the currency you purchased. If you bought 1,000 units (called a micro lot) each pip is worth $0.10, so you would calculate your profit as (50 pips * $0.10) = $5 for a 50 pip gain. If you bought a 10,000 unit (mini lot), then each pip is worth $1, so your profit ends up being $50. If you bought a 100,000 unit (standard lot) each pip is worth $10, so your profit is $500. This assumes you have a USD trading account.
U.S. President Richard Nixon’s nullification of the Bretton Woods Accord in 1971 effectively ended the fixed price peg of the US Dollar — and by extension many other world currencies — to gold. The US Dollar officially became a floating fiat currency and was adopted as a reserve currency by many foreign nations, who continue to use it as a reserve currency today.

The main participants in this market are the larger international banks. Financial centers around the world function as anchors of trading between a wide range of multiple types of buyers and sellers around the clock, with the exception of weekends. Since currencies are always traded in pairs, the foreign exchange market does not set a currency's absolute value but rather determines its relative value by setting the market price of one currency if paid for with another. Ex: US$1 is worth X CAD, or CHF, or JPY, etc.

To find out how many euros it costs to buy one U.S. dollar, flip the pair to USD/EUR. To find out this rate, divide 1 by 1.3635 (or whatever the current rate is). The result is 0.7334. It costs 0.7334 euros to buy one USD based on the current market price. The price of the currency pair constantly fluctuates, as transactions occur around the globe, 24-hours a day during the week.  
Governments / Central banks – A country’s central bank can play an important role in the foreign exchange markets. They can cause an increase or decrease in the value of their nation’s currency by trying to control money supply, inflation, and (or) interest rates. They can use their substantial foreign exchange reserves to try and stabilize the market.
While each exchange functions independently, they all trade the same currencies. Consequently, when two exchanges are open, the number of traders actively buying and selling a given currency dramatically increases. The bids and asks in one forex market exchange immediately impact bids and asks on all other open exchanges, reducing market spreads and increasing volatility. This is certainly the case in the following windows:

In this view, countries may develop unsustainable economic bubbles or otherwise mishandle their national economies, and foreign exchange speculators made the inevitable collapse happen sooner. A relatively quick collapse might even be preferable to continued economic mishandling, followed by an eventual, larger, collapse. Mahathir Mohamad and other critics of speculation are viewed as trying to deflect the blame from themselves for having caused the unsustainable economic conditions.

On 1 January 1981, as part of changes beginning during 1978, the People's Bank of China allowed certain domestic "enterprises" to participate in foreign exchange trading.[51][52] Sometime during 1981, the South Korean government ended Forex controls and allowed free trade to occur for the first time. During 1988, the country's government accepted the IMF quota for international trade.[53]
For instance, if we take a less active period between 5 pm – 7 pm EST, after New York closes and before Tokyo opens, Sydney will be open for trading but with more modest activity than the three major sessions (London, US, Tokyo). Consequently, less activity means less financial opportunity. If you want to trade currency pairs like EUR/USD, GBP/USD or USD/CHF you will find more activity between 8 am – 12 am when both Europe and the United States are active.
When you trade forex, you're effectively borrowing the first currency in the pair to buy or sell the second currency. With a US$5-trillion-a-day market, the liquidity is so deep that liquidity providers—the big banks, basically—allow you to trade with leverage. To trade with leverage, you simply set aside the required margin for your trade size. If you're trading 200:1 leverage, for example, you can trade £2,000 in the market while only setting aside £10 in margin in your trading account. For 50:1 leverage, the same trade size would still only require about £40 in margin. This gives you much more exposure, while keeping your capital investment down.
