The currency heat map shows the largest rises and falls in currency pairs over the last 24 hours, identifying where
trading has been most active.
You can filter the list so that it only shows the movements for a single currency such
as EUR or USD. For consistency and ease of comparison, all movements will then be stated
in terms of that base currency. For example, if you select USD then the list will show
you the moves for USD/JPY, USD/EUR (instead of EUR/USD) so that you can more easily compare
the dollar's direction against other currencies.
