Hi Ivan, thanks a lot for your help, I try to use very useful new indicator posted by you, “PRC_Range-Filtered-Trend-Signal” in timeframe 1 minute using as confirmation result of same indicator in timeframe 3 minutes.
Unfortunatelly the result in attach is not ok, I see just red trend.
Please could you check it? I post my code below ( just adding the timeframe 3 minutes in line 3 and default timeframe in line 133. Moreover Ivan suggested me to change line 22 with Barindex <= 2 instead <=1
Thank you in advance!
Franco
