Fractals with the ability to set range. Fractal range is determined by value of indicator input parameter:

input uint RangeFractal=5; //fractal range (odd numbers no less than 3)

Even numbers of this parameter are modified to odd numbers increasing per one odd!

Remind that standard 5-th range fractals are available in a complete МetaTrader5.

This indicator was first implemented in MQL4 and published in Code Base at mql4.com on 27.06.2009.
