Thank you so much again, sir! I really appreciate it.mladen wrote: Sat Dec 16, 2017 5:21 pm
It does
That is a wrongly coded kind of double smoothed stochastic. Here is a version that does not repaint

It repaints. After correcting it it will not be the same.Naughty 77 wrote: Thu Jan 04, 2018 12:59 am Hi All
Would you kindly confirm if the attached indicator repaints ? Ifso, can it be corrected ?
