The most popular currency pair in forex market is EURUSD. According to many successful traders having a favorite currency pair is not a good idea. Do you have a favorite currency pair and why?
My favorite currency pairs are those with a high ratio of daily volatility to average spread. And that ratio changes from time to time. EUR/JPY, EUR/USD and USD/JPY are among the best in those terms.
To trade successfully you need to become very intimate with the currency pair you intend to trade. Once you are a consistently profitable trader trading that one pair, only then is it acceptable to begin looking at other pairs.
