Hello cbadr,

I don't see any kind of question attached to your post so I am unsure what you need help with here, please update your post with your question.

I updated my post above due to a bug. i think it's clear now

Hello cbadr,

To make unique drawing objects you need to use unique tag names. You can add the CurrentBar to the tag like the following

"buyers" + CurrentBar
"sellers" + CurrentBar

Sorry i don't understand, can you please develop?

Hello cbadr,

You would need to change the tags that you are using for the Draw.Dot syntax, you can edit the tag from being "buyers" to "buyers" + CurrentBar to make it unique for every bar.
