Since currencies are traded in pairs, it’s impractical and not very useful to draw a pure USD currency chart. Instead we have the option of drawing (or rather having the software plot for us) a chart of the USDJPY pair, or the AUDUSD pair, since it is only possible to quote a currency in terms of another. On the other hand, there are some forex charts that take weighted average of such currency pairs to derive an overall index for a currency. The famous USD index, is a good example.
Currency values never remain stationary, and it is this dynamic that gave birth to one of the most popular trading strategies of all time, the carry trade. Carry traders hope to earn not only the interest rate differential between the two currencies (discussed above), but also look for their positions to appreciate in value. There have been plenty of opportunities for big profits in the past. Let’s take a look at some historical examples. 

For retail clients, leverages of up to 1:30 for currency pairs and 1:20 for indices are available. For professional clients, a maximum leverage of up to 1:500 is available for currency pairs, indices, energies and precious metals. Both retail and professional status come with their own unique benefits and trade-offs, so it's a good idea to investigate them fully before trading.
