The big currencies in most people’s estimation are the US dollar (USD), Euro (EUR), yen (JPY), pound (GBP), Swiss frank (CHF), and the Canadian and Australian dollars (CAD and AUD). Therefore, there are 6 major pairs where USD is combined with any other of the majors. Cross pairs are those excluding USD, for example CBP/CHF. The exception could be a broker will offer the currency of their own country at cheap rates regardless of whether that currency isn’t a major. This is especially true for secondary currencies like the New Zealand and Singapore dollars that are close to making it into the majors apropos daily trading volume. So that you can trade any major pair or cross of the majors but unless you have reasons for doing otherwise, most beginners are suggested to begin with EUR/USD for many trading. This is the highest traded pair giving it a number of advantages . First, there is a lot of competition between brokers so the spread is usually lowest for this pair. Third, forex reports alerts have a lot of reports about these currencies so you aren’t so certain to get caught out by unexpected announcements. If you are using an expert counsel or foreign exchange trading robot, on the other hand, it may be set up for other pairs. In that case it is best to use it according to its settings. Androids often use systems that are pair categorical, i.e. That won’t work so well on any but the suggested pairs, so those will be the best currency exchange pairs for an expert counsel.
