Supply and Demand zones indicator?

Sorry but I do not "...have a supply and demand zones indicator..."

Since you did not provide any specifications for how these "zones" are determined, it is impossible to state whether it can be built for Thinkorswim. My first guess is that it cannot be constructed on Thinkorswim. This platforms lacks the programming tools required to build an advanced chart study of this type.

And even if it were possible, the amount of time required to write that code would be light-years beyond the scope of complexity for the free solutions I provide in this forum. It would take hours to write this code and I only allocated 15 minutes toward each free solution I provide in this forum.
