Currency carry trade refers to the act of borrowing one currency that has a low interest rate in order to purchase another with a higher interest rate. A large difference in rates can be highly profitable for the trader, especially if high leverage is used. However, with all levered investments this is a double edged sword, and large exchange rate price fluctuations can suddenly swing trades into huge losses.
Foreign exchange market is composed of different participants, also called Forex market players, who trade on the market for quite various reasons. This means that participating in Forex market transactions does not take place simply for speculative purpose. Each of the participants plays its own role in the market providing the latter’s wholeness and stability.
Currencies are always traded in pairs, so the "value" of one of the currencies in that pair is relative to the value of the other. This determines how much of country A's currency country B can buy, and vice versa. Establishing this relationship (price) for the global markets is the main function of the foreign exchange market. This also greatly enhances liquidity in all other financial markets, which is key to overall stability.

Another possible source of confusion is that GMT is always just that, summer, winter and fall. Eastern time, however, comes in two flavors: Eastern Standard Time (EST) and Eastern Daylight Time. Since the agreed-upon reference time worldwide is actually GMT, which has no Greenwich Mean Daylight Savings Time, this means that a New York trader who chooses to reference Eastern time rather than GMT, must keep in mind that during Daylight Savings Time in New York, the trading hours shift by an hour because the GMT reference time, needless to say, does not shift.
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.
However, proponents of sound money like Bitcoin and gold take a hesitant outlook on the long-term sustainability of floating fiat currencies. The forex market’s size and complexity are a direct result of the dissolution of Bretton Woods and are indicative of the challenges required for an international monetary order of various national floating currencies to persist without the potential for black swan events.
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.
