One way to deal with the foreign exchange risk is to engage in a forward transaction. In this transaction, money does not actually change hands until some agreed upon future date. A buyer and seller agree on an exchange rate for any date in the future, and the transaction occurs on that date, regardless of what the market rates are then. The duration of the trade can be one day, a few days, months or years. Usually the date is decided by both parties. Then the forward contract is negotiated and agreed upon by both parties.
In the context of the foreign exchange market, traders liquidate their positions in various currencies to take up positions in safe-haven currencies, such as the US dollar. Sometimes, the choice of a safe haven currency is more of a choice based on prevailing sentiments rather than one of economic statistics. An example would be the financial crisis of 2008. The value of equities across the world fell while the US dollar strengthened (see Fig.1). This happened despite the strong focus of the crisis in the US.
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.
Another element of the service provided is the margin requirements and level of leverage available. While there is no need to choose the highest level of available leverage when you start trading Forex, simply knowing that a broker offers the highest level of leverage approved by their regulator means that, as your experience grows, you can start to increase your leverage according to your preferences.
