This form of analysis involves look keeping track of real-world events that might influence the values of the financial instruments you want to trade. For instance, the value of the Australian Dollar might fluctuate following a Reserve Bank of Australia interest rate announcement, which will then affect the movements of all currency pairs including the AUD.
Day trading can take place in any market, but is commonly referred to in the context of either the Forex trading market or the stock trading market. In order to be successful as a Forex day trader, you need to have a decent amount of capital, and a good amount of knowledge of the market behind you. However, having this doesn't necessarily guarantee success. This is especially true when 'invisible hands' are at work, and when the prices fluctuate enormously during intraday Forex trading.
Unlike stock markets, which can trace their roots back centuries, the forex market as we understand it today is a truly new market. Of course, in its most basic sense - that of people converting one currency to another for financial advantage - forex has been around since nations began minting currencies. But the modern forex markets are a modern invention. After the accord at Bretton Woods in 1971, more major currencies were allowed to float freely against one another. The values of individual currencies vary, which has given rise to the need for foreign exchange services and trading.
