In addition to dividing your investment in small portions you also need to crack the beneficial currency pairs that are capable of earning you a handful of return on investment.\u00a0 Below are our tips on cracking the code to understanding currency pairs: Understanding a Currency Pair: A currency pair is the combination of two different currencies. The value of either currency is quoted against the other one. The currency whose value is being quoted is called the base currency while the second one is termed as the quote currency. Currency pairs are used to compare the value of one currency against the other. It is the base currency against the quote currency. A currency pair that is actually a comparison states how much of the quote currency is required to purchase a unit of base currency. Currencies are usually defined and recognised through an ISO currency code which is a combination of three alphabetic letters, for instance a United States Dollar is termed as USD in forex market. Basically, when an order is placed for a currency pair the base currency is purchased in return of the required amount of quote currency. In other words, base currency is purchased by selling quote currency. The most in demand currency pair is EUR\/USD and is considered as the most liquid currency pair in the world and USD\/JPY is the second most popular currency pair in the international forex market. Here EUR denotes European Euro while JPY denotes Japanese Yen. Understanding the Basics: The International Foreign Exchange market is the platform for trade of currency pairs. It is the largest and most liquid market in the financial world even when it is compared with some of the largest stock markets across the world. This market enables investors to buy, sell, and exchange currencies. Additionally, it allows investors to speculate currencies as well. Investors and other parties can also convert currencies here for international trade process and investment purposes.\u00a0 The forex market stays open throughout the day and five days a week excluding the weekend and holidays. You can observe a humongous amount of trade data and volume in this market. The trades occurring in this market involve simultaneous purchase of a currency which is the base currency and trade of another which is known as quote currency. However, the currency pair is identified as a single unit itself. If you are investing in a currency pair, you are actually buying the base currency and selling equivalent amounts of quoted currency for the purchase of base currency. In other words, a currency pair is a tool or an instrument that is either sold or purchased. The bid or buy price denotes how much quote currency you need to buy a single unit of base currency. It is not necessary that the base price should have a higher value as compared to the quote currency. Sometimes a single unit of base currency is actually cheaper than the single unit of quoted currency.
