The most common type of forward transaction is the foreign exchange swap. In a swap, two parties exchange currencies for a certain length of time and agree to reverse the transaction at a later date. These are not standardized contracts and are not traded through an exchange. A deposit is often required in order to hold the position open until the transaction is completed.
Currency and exchange were important elements of trade in the ancient world, enabling people to buy and sell items like food, pottery, and raw materials.[9] If a Greek coin held more gold than an Egyptian coin due to its size or content, then a merchant could barter fewer Greek gold coins for more Egyptian ones, or for more material goods. This is why, at some point in their history, most world currencies in circulation today had a value fixed to a specific quantity of a recognized standard like silver and gold.
Demo Account: Although demo accounts attempt to replicate real markets, they operate in a simulated market environment. As such, there are key differences that distinguish them from real accounts; including but not limited to, the lack of dependence on real-time market liquidity, a delay in pricing, and the availability of some products which may not be tradable on live accounts. The operational capabilities when executing orders in a demo environment may result in atypically, expedited transactions; lack of rejected orders; and/or the absence of slippage. There may be instances where margin requirements differ from those of live accounts as updates to demo accounts may not always coincide with those of real accounts.
If your FOREX broker offers you a leverage of 1:100 you can trade with a 100 times more money than you have in your deposit. This means that if you want to buy 100 000 EUR/USD you only need to have a 1 000 actual euros. With this kind of leverage you can take a position that is a 100 times larger in value and expect a 100 times bigger profits or losses, therefore great care is advisable when placing your trade. Equities, on the other hand, are traded without leverage.
Gold Standard System was formed in 1875. The main idea behind it was that governments guaranteed that a currency would be backed by gold. All the major economic countries defined an amount of currency to an ounce of gold as the value of their currencies in terms of gold and the ratios for these amounts became the exchange rates for these currencies. This marked the first standardized means of currency exchange in history. However, World War I caused a breakdown of the gold standard system as countries sought to pursue economic policies which would not be constrained by the fixed exchange rate system of the Gold Standard.
So, yes, at any given trading center, it's an eight hour day. But that really doesn't matter, because somewhere in the world trading centers are open. You can trade anytime you want, although you should also note that you'll get the narrowest spreads -- the broker's profit margin -- when the maximum number of trading centers are open or, more precisely, when the trading volume for your currency trade is greatest. 
Just like stocks, you can trade currency based on what you think its value is (or where it's headed). But the big difference with forex is that you can trade up or down just as easily. If you think a currency will increase in value, you can buy it. If you think it will decrease, you can sell it. With a market this large, finding a buyer when you're selling and a seller when you're buying is much easier than in other markets. Maybe you hear on the news that China is devaluing its currency to draw more foreign business into its country. If you think that trend will continue, you could make a forex trade by selling the Chinese currency against another currency, say, the US dollar. The more the Chinese currency devalues against the US dollar, the higher your profits. If the Chinese currency increases in value while you have your sell position open, then your losses increase and you want to get out of the trade.
One of the best ways to learn about forex is to see how prices move in real time and place some trades using fake money by using an account called a paper-trading account (so there is no actual financial risk to you). Several brokerages offer online or mobile phone app-based paper trading accounts that work exactly the same as live trading accounts, but without your own capital at risk.

In July 1944, representatives from the Allied nations brought forward the importance of a monetary system which would fill the gap left behind the gold standard. They arranged a meeting at Bretton Woods, New Hampshire, to set up a system that would be called the Bretton Woods system of international monetary management. The creation of Bretton Woods System led to the formation of fixed exchange rates as the United States defined the value of US dollar in terms of gold equal to $ 35 for one ounce and other countries pegged their currencies to the dollar. The US dollar became the main reserve currency and the only currency that was backed by gold. However, in 1970 the U.S. gold reserves were so depleted that it was impossible for the U.S. treasury to cover all the reserves held by foreign central banks.

The foreign exchange market is the "place" where currencies are traded. Currencies are important to most people around the world, whether they realize it or not, because currencies need to be exchanged in order to conduct foreign trade and business. 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 same goes for traveling. A French tourist in Egypt can't pay in euros to see the pyramids because it's not the locally accepted currency. As such, the tourist has to exchange the euros for the local currency, in this case the Egyptian pound, at the current exchange rate.
