A currency type is simply a type which is intended to be widely held and passed around, such as Binary Currency or Currencies, rather than a single type which is useful for internal/external applications but which you would not normally use on an everyday basis, such as ArraySlice. The idea behind this approach is that, since it is meant to be used widely, you would naturally need an array of currencies available for consumers and businesses alike. Rather than each business getting hold of a single ‘run’ of the currency, you would get a ‘feedback’ of the market at all times, with every purchase/sale of currency making a difference in its status.
There are many instances where a user will need to know what currency pairs are being traded. This may be because they are looking to invest in a particular country, wanting to make investments within their host country. These situations could be highlighted by the currency feed or trend indicator on a Forex trading platform, providing instant information on the state of the exchange market at any given moment. For example, if the pound Sterling is weakening against the American dollar, then the exchange rate will show the current trend line for that particular currency, making it easier for people to judge whether a move to the dollar would benefit them. The same principle would apply for currencies from other countries.
Another example of when a person may want to know about the exchange rates of currency would be if they are going on holiday, either for work or pleasure. Most people tend to exchange their British pound for U.S. dollars, but what about when they are visiting friends overseas? Even though the British pound is generally weak against the U.S. dollar, it may still gain in value against other currencies during their stay, which would mean that they would have made some money from their exchange. For this reason, it is good practice to keep a range of currencies on hand, so that if the pound does weaken against the U.S. dollar, then you will have other currencies to fall back to.
There are many more instances where someone may wish to read up on foreign exchange rates. For example, when planning a vacation, it is often best to know the currency exchange rates of the country in which you are going to spend your holiday. For instance, if you are going to spend two weeks in Australia, it would be logical to purchase dollars at the current exchange rate, and then exchange them back when you get home. Conversely, if you are going to Spain, you would do well to purchase Spanish pounds at their current value, and then change them back over the coming weeks. If you are going to Canada, it may even be beneficial financially to purchase Canadian dollars at the time of purchase, and then change them back before your vacation ends. This will ensure that you do not lose out on any amount of money due to unfavorable exchange rates.
When you are traveling abroad for business, it is important to keep up with all of the current news and political events. If you are paying twenty or thirty thousand pounds per week for a three-month business trip, and the Canadian dollar drops to one hundred US dollars, it would make sense for you to hold off on your purchases until the ninety days is up. The same goes for purchasing items such as clothing, electronics, and other consumable items. If the prices change by the slightest bit, and they do often, you can end up losing out by selling at an incorrect price to a competitor.
For this reason, it is smart to do some research, and to stay up to date on everything that is happening in both the domestic and foreign exchange markets. As I mentioned earlier, the term “forex” refers to the foreign exchange market. Forex exchanges buy and sell currencies from all around the world, and are often done electronically. For instance, during a recent economic slowdown in the United States, forex traders sold U.S. dollars in the hopes that the dollar would strengthen against another currency. At the beginning of the trading day, the exchange rate between the two currencies was negative, meaning that sellers paid more for the dollar, and buyers paid less. However, once the trading day was over, the exchange rate turned positive, meaning that buyers were able to purchase U.S. dollars and sellers were able to accept the payment for their currency from those who had purchased U.S. dollars.
