Transactions in foreign currencies are not centralized on an exchange, unlike say the NYSE, and thus take place all over the world via telecommunications. Trade is open 24 hours a day from Sunday afternoon until Friday afternoon (00:00 GMT on Monday to 10:00 pm GMT on Friday). In almost every time zone around the world, there are dealers who will quote all major currencies. After deciding what currency the investor would like to purchase, he or she does so via one of these dealers (some of which can be found online). It is quite common practice for investors to speculate on currency prices by getting a credit line (which are available to those with capital as small as $500), and vastly increase their potential gains and losses. This is called marginal trading.
FOREX investing is one of the most potentially rewarding types of investments available. While certainly the risk is great, the ability to conduct marginal trading on FOREX means that potential profits are enormous relative to initial capital investments. Another benefit of FOREX is that its size prevents almost all attempts by others to influence the market for their own gain. So that when investing in foreign currency markets one can feel quite confident that the investment he or she is making has the same opportunity for profit as other investors throughout the world. While investing in FOREX short term requires a certain degree of diligence, investors who utilize a technical analysis can feel relatively confident that their own ability to read the daily fluctuations of the currency market are sufficiently adequate to give them the knowledge necessary to make informed investments.
