Support/Resistance Zones for ThinkorSwim


Well-known member
Support/Resistance or Supply/Demand whichever you prefer. Based on pivots and ATR. Change the n to get zones for the time you wish.

Update: ATR is now straight lines and user can input ATR multiple.
New share: https://tos.mx/Lv0FsZi


# Support/Resistance Zones around pivot S/R points.
#Added the zones using ATR to the Theotrade Pivots study.
#Additions by Horserider 9/30/2019

Thanks for sharing the script. Very useful. For anyone with a shrinking chart after adding this indicator, be sure to uncheck the "Fit Studies" option on your chart (you can do so by left-click > Chart Scale).


I checked the source code and it looks like the script contains some of Mobuis' work from his other indicators called WolfWave and/or Pivot Array. If that's the case I would recommend keeping his old header or give credit to the developer.

Very nice job "horserider! I like the the idea of using ATR as the zones - thank you for posting.

@mc01439, Currently N vaule set for 21. Do you know what is the value for other time frame like 1mts, 5mts,15mts,hour,day,week and Monthly.

@San - Like @BenTen said you need to test what works best for you and your style. I like n @ 21 for 8 range bars. Someone else more than likely would use something else. I do not trade minute charts but 21 seems to paint a lot of lines, too many for my taste. I like a clean chart with only key points marked. More is not better from my experience. The best to you.

@BenTen, what is the lookback period for this time frame " 1mts, 5mts,15mts,hour,day,week and Monthly."
@San, start at n=1 or 2 and add to it for each time frame until you get what works for you.
This is about you and your time frame & the way you like to see consolidation or pivots or S/R.
Trial and error until it is tuned in to your liking.

Appreciate you putting this together. Anyway to just have certain S/R zones only the charts? Tried unticking plots and didn't work for me.


New member
I have looked in there and didn't find a supply/demand zone indicator. I'll go look at it again. Also, from what I've read supply and demand zones are different than supply and resistance lines. Regardless, I will not pay for an indicator...

@shizah Please tell us how they are different. You have a solution just adjust it to your trading plan.

I do not understand your statement "Anyway to just have certain S/R zones only the charts? Tried unticking plots and didn't work for me. " If you care to explain in detail maybe something can be adjusted to what you want.

No one can do it for you.
I appreciate your answer.. I don't know the script and i am new to this concept.. That's why i ask the request. If you don't want to help my concern that's fine instead of saying " No one can do it for you " .
