Investors should stick to the major and minor pairs in the beginning. This is because it will be easier to find trades, and lower spreads, making scalping viable. Exotic pairs, however, have much more illiquidity and higher spreads. In fact, because they are riskier, you can make serious cash with exotic pairs, just be prepared to lose big in a single session too.
Forex is the one financial market that never sleeps, meaning you can trade at all hours of the day (or night). Unlike the world's stock exchanges, which are located in physical trading rooms like the New York Stock Exchange or the London Stock Exchange, the Forex market is known as an 'Over-the-counter market' (or OTC). This means that the trades take place directly between the parties holding the currencies, rather than being managed via an exchange.
For instance, if you opened a long trade on the GBP/USD currency pair, and the pair increased in value, the price limit at which the trade should close (the stop loss) would climb alongside the price of the currency pair. If the value of the GBP/USD then started to fall, the trade would be closed as soon as it hit your stop loss, preserving any profits you had made beforehand.
International parity conditions: Relative purchasing power parity, interest rate parity, Domestic Fisher effect, International Fisher effect.

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.
