What are the Possibilities of Currency Crosses?

Crosses can be as volatile as the most heavily-traded stocks during the heyday of the Nasdaq bubble or as sedate as a 'AAA'-rated dividend-yielding utility share on the NYSE. Trading in crosses can focus on carry strategies that try to profit from interest rate differentials between the currencies or it can be focused on pure capital gains speculation. Trades can also be based on economic analysis or political news. Some crosses can trend for months, while others will be highly range-bound. In short, the possibilities with currency crosses are endless.
