This little tip is a fast way to group your currencies for quick reference when there is a good move in one group of currencies. i.e. if the JPY pairs are moving, you could group all the JPY pairs for easy access. Just right click in the Market Watch box to get the pop up menu. You can create several sets of symbols and switch between them, if necessary. This can be very useful if you work with different groups of symbols (currency pairs, shares, futures, etc.). Hide all "excessive" symbols and save the set obtained.
