Flights to quality: Unsettling international events can lead to a "flight-to-quality", a type of capital flight whereby investors move their assets to a perceived "safe haven". There will be a greater demand, thus a higher price, for currencies perceived as stronger over their relatively weaker counterparts. The US dollar, Swiss franc and gold have been traditional safe havens during times of political or economic uncertainty.
Leverage: Leverage is capital provided by a Forex broker to bolster their client's trading volume. For example, if you use a 1:10 rate of leverage and have $1,000 in your trading account, you can trade $10,000 worth of a currency pair. If the trade is successful, leverage will maximise your profits by a factor of 10. However, please note that leverage also multiplies your losses to the same degree, so it should be used with caution. If your account balance falls below $0, you may trigger a broker's negative balance protection settings (if trading with an ESMA regulated broker), which will result in the trade being closed. Fortunately, this means that your balance cannot move below $0, so you will not be in debt to the broker.
Being the largest, most active financial market on the globe, it is also the world's most liquid market, meaning it is easy for traders to enter into, as well as exit trades, and for the most liquid pairs, they can do so at a very low cost (even less than a single pip!). This also means that the Forex market is very volatile, creating many opportunities for traders to make a profit on both the positive and negative movements of currency pairs.
Forex is a portmanteau of foreign currency and exchange. Foreign exchange is the process of changing one currency into another currency for a variety of reasons, usually for commerce, trading, or tourism. According to a recent triennial report from the Bank for International Settlements (a global bank for national central banks), the average was more than $5.1 trillion in daily forex trading volume.
