Description:

In 2009 I published the indicator for DXY - Dollar Index - it was well received and downloaded many times in English and Russian. Now having found the definition of the Euro Index I submit this for the community's use and comment.

The definition can be found at Forex Ltd

Recommendations:

• The periods for the moving averages can be changed - defaults are 20 and 40
• The indicator will work on any chart and on any period
