Hello dlv123,

Thank you for your post.

The tag for a drawing object is a unique ID used to reference that specific drawing object. If you reuse the same tag, each time you call a drawing object the same drawing object will be referenced and the existing drawing object will be modified instead of a new object being created.

For example, if you tag your drawing object “myTag”, each time you use “myTag” the same drawing object will be modified.

To create a new drawing object, use a new unique string as the tag each time you call a Draw method. As an easy way to make a new string unique add ‘CurrentBar’ to the string.

Help Guide: NinjaScript > Language Reference > Common > OnBarUpdate() > CurrentBar

The code below will create a new red dot one tick below the low each time it is called.

Draw.Dot(this, "myTag" + CurrentBar, true, 0, Low[0] - TickSize, Brushes.Red);

Please let us know if you have any further questions.
