Indicator Description
Hi All,
This is a new indicator requested by Zenoni on the following forum topic.
This indicator appeared in TASC magazine April 2007 and available in Metatrader MQL4 Codebase website. Iis commonly called as Fractal Dimension Index (FDI). It's a nondirectional index indicator that measures the strength of the trend. It is a indicator that shows strength of trend as compared to the vertical horizontal filter, ADX, DMI. It doesn't shows a trading signal, because this indicator can be used for filtering only. If you want to learn more about this indicator you can google it.
