I would like to introduce you Standard deviation zones horizontals. It draws line horizontals on high and low st dev zone. The colors are dynamic depending whether price is below or above the line.
Credit is due to @Zeiierman for st dev zone calculation so shout out to him.
There are various sections in setting:
general setting where you can select source for zone calculation
show and hide section of the first timeframe
show and hide section of the second timeframe
Be aware that when new zone starts and is not finished yet than the top will trail the high of unfinished zone that could be also at the high of current candle and next candle it can change
Any suggestions are welcomed
