Again GREAT thanks to tmc. and I have just uploaded the corrected version

Thanks! Very useful!

Then change the line so:

[Indicator(IsOverlay = true, AutoRescale = false, TimeZone = TimeZones.UTC, AccessRights = AccessRights.None)]

A note: the indicator interferes with the chart zoom, that wants to keep the full price line within the visible graph

But this is a "static" indicator

I mean: I put it in all my templates, so It immediately remember me where the full prices are

Then if the full prices are within my "trading range" I keep the indicator active as a constant warning, otherwise if the full prices are long away, I remove the indicator because it becomes unuseful

A very valuable job, thank you!

Thanks, a very good job!

For those who have trouble seeing the Renko, I noticed that it works perfectly if I use any timeframe BUT DIFFERENT FROM M1
