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.
Foreign exchange fixing is the daily monetary exchange rate fixed by the national bank of each country. The idea is that central banks use the fixing time and exchange rate to evaluate the behavior of their currency. Fixing exchange rates reflect the real value of equilibrium in the market. Banks, dealers, and traders use fixing rates as a market trend indicator.
Traders at the banks would collaborate in online chat rooms. One trader would agree to build a huge position in a currency, then unload it at 4 p.m. London Time each day. That's when the WM/Reuters fix price is set. That price is based on all the trades taking place in one minute. By selling a currency during that minute, the trader could lower the fix price. That's the price used to calculate benchmarks in mutual funds. Traders at the other banks would also profit because they knew what the fix price would be.
The mere expectation or rumor of a central bank foreign exchange intervention might be enough to stabilize the currency. However, aggressive intervention might be used several times each year in countries with a dirty float currency regime. Central banks do not always achieve their objectives. The combined resources of the market can easily overwhelm any central bank. Several scenarios of this nature were seen in the 1992–93 European Exchange Rate Mechanism collapse, and in more recent times in Asia.
To use an extreme example, imagine holding an account balance of 2,000 EUR and putting all of that on a single trade. If the trade goes badly, you will have lost your entire investment, and because the Forex market can move very quickly, losses can also happen very quickly. This is where risk management is essential - to help you minimise losses and protect any profits you do make. The key areas to consider when managing your Forex trading risk are trading psychology, and money management.
Prepare for the worst: While this might sound pessimistic, in Forex trading it is better to prepare for the worst than expect the best. There have been many times in history when financial markets and individual trading instruments have experienced sudden spikes or drops in value. By considering the worst possible outcome of a trade, you can take measures to protect yourself, should this happen, such as by setting a stop loss in advance.
Trader's also have the ability to trade risk-free with a demo trading account. This means that traders can avoid putting their capital at risk, and they can choose when they wish to move to the live markets. For instance, Admiral Markets' demo trading account enables traders to gain access to the latest real-time market data, the ability to trade with virtual currency, and access to the latest trading insights from expert traders.
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.
