Knowing how the industry is mapped out is important, because the collective combination of all participants creates the market you trade in. The relative weight of the trading party to the market is measured by how much money that party manages – from billion dollar hedge funds and investment banks, to private traders with a few thousand dollars in action.
Reliability: Is the trading platform reliable enough for you to achieve the trading results you want? Being able to rely on the accuracy of prices quoted, the speed of data being transferred, and fast order execution is essential to being able to trade Forex successfully, particularly if you plan to use very short-term strategies like scalping. The information must be available in real time, and the platform must be available at all times when the Forex market is open. This ensures that you can take advantage of any opportunities that may present themselves.
Factors like interest rates, trade flows, tourism, economic strength and geopolitical risk affect supply and demand for currencies, which creates daily volatility in the forex markets. An opportunity exists to profit from changes that may increase or reduce one currency's value compared to another. A forecast that one currency will weaken is essentially the same as assuming that the other currency in the pair will strengthen because currencies are traded as pairs.
One unique aspect of this international market is that there is no central marketplace for foreign exchange. Rather, currency trading is conducted electronically over-the-counter (OTC), which means that all transactions occur via computer networks between traders around the world, rather than on one centralized exchange. The market is open 24 hours a day, five and a half days a week, and currencies are traded worldwide in the major financial centers of London, New York, Tokyo, Zurich, Frankfurt, Hong Kong, Singapore, Paris and Sydney—across almost every time zone. This means that when the trading day in the U.S. ends, the forex market begins anew in Tokyo and Hong Kong. As such, the forex market can be extremely active any time of the day, with price quotes changing constantly.
