Description:
Back in 2009, I launched the DXY - Dollar Index indicator, and it really took off, with plenty of downloads across both English and Russian-speaking traders. Now, I’m excited to share my latest find: the Euro Index (EURX). This indicator is all set for you to use and provide feedback on.
You can find the detailed definition of the Euro Index at Forex Ltd.
