Factors affecting forex trading

Although exchange rates are affected by many factors, in the end, currency prices are a result of supply and demand forces. Supply and demand factors are constantly shifting, and the price of one currency in relation to another shifts accordingly. No other market encompasses (and distills) as much of what is going on in the world at any given time as foreign exchange.

Supply and demand for any given currency, and thus its value, are not influenced by any single element, but rather by several . These elements generally fall into three categories:

Economic factors.
These include economic policy, disseminated by government agencies and central banks, economic conditions, generally revealed through economic reports, and other economic indicators.
Economic policy comprises government fiscal policy (budget/spending practices) and monetary policy (the means by which a government's central bank influences the supply and "cost" of money, which is reflected by the level of interest rates).

Political conditions
Internal, regional, and international political conditions and events can have a profound effect on currency markets.
For instance, political upheaval and instability can have a negative impact on a nation's economy. The rise of a political faction that is perceived to be fiscally responsible can have the opposite effect. Also, events in one country in a region may spur positive or negative interest in a neighboring country and, in the process, affect its currency.

Market psychology
Market psychology and trader perceptions influence the foreign exchange market in a variety of ways:

1. Flights to quality: Unsettling international events can lead to a "flight to quality" with investors seeking a "safe haven". There will be a greater demand, thus a higher price, for currencies perceived as stronger over their relatively weaker counterparts.
2. Long-term trends: Currency markets often move in visible long-term trends. Although currencies do not have an annual growing season like physical commodities, business cycles do make themselves felt. Cycle analysis looks at longer-term price trends that may rise from economic or political trends.
3. "Buy the rumor, sell the fact": This market truism can apply to many currency situations. It is the tendency for the price of a currency to reflect the impact of a particular action before it occurs and, when the anticipated event comes to pass, react in exactly the opposite direction. This may also be referred to as a market being "oversold" or "overbought". To buy the rumor or sell the fact can also be an example of the cognitive bias known as anchoring, when investors focus too much on the relevance of outside events to currency prices.
4. Economic numbers: While economic numbers can certainly reflect economic policy, some reports and numbers take on a talisman-like effect - the number itself becomes important to market psychology and may have an immediate impact on short-term market moves. "What to watch" can change over time. In recent years, for example, money supply, employment, trade balance figures and inflation numbers have all taken turns in the spotlight.
5. Technical trading considerations: As in other markets, the accumulated price movements in a currency pair such as EUR/USD can form patterns that may be recognized and utilized by traders for the purpose of entering and exiting the market, leading to short-term fluctuations in price. Many traders study price charts in order to identify such patterns
