Whether you are a beginner trader or a pro, it is best to trade with what you see and not what you think. For example, you might think that the US dollar is overvalued and has been overvalued for too long. Naturally, you will want to short and you might be right eventually. But if the price is moving up, it does not matter what you think. In fact, it doesn't matter what anybody thinks – the price is moving up and you should be trading with the trend.
Use a stop loss: A stop loss is tool that traders use to limit their potential losses. Simply put, it is the price level at which you will close a trade that isn't moving in your favour, thereby preventing any further losses as the market continues to move in that direction. You can also use a stop loss to conserve any profits you might have already made - the tool to achieve this is known as a 'trailing' stop loss, which follows the direction of the market.
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.
