While trading you have to choose among many pairs. Some people prefer to trade with USD dollar with Euro because they are the bigger currencies nowadays. Other people prefer to trade their own currency with another currency without thinking if their currency will have big increases or not.
I have tried trading USD Dollar with Euro and it is a very good pair. Those currencies are having high increases and decreases and you can make profit easily. The same way you can have big looses too..
Some expert traders are recommending trading USD dollar with other currencies than Euro like Yen. They say that a "strong" currency and another which is not so "strong" is a good pair which can be managed easier from newbies too.
Which pair do you prefer to use while trading? Are you trading different pairs each time or you have your best one?
