Does this save resources

[Mindset]

I found this snippet in some code produced by NinjaTrader.
It effectively allows the user to limit the number of Drawings/Plots the indicator does eg last 10
or show all of them (99)

marker_Count ++;
if(Number_Of_Markers != 99 && Number_Of_Markers <= marker_Count)
marker_Count = 1;//reset ie once it hits marker_Count it reuses the tag so limiting your number of plots

Draw.Text(this,"Tag"+(Number_Of_Markers == 99 ? CurrentBar: marker_Count),......

My question is does it really save resources?
I like it and it makes sense but I am only an intermediate level coder so it would be nice to know if
it's really useful.

thank you

Hello Mindset,

Thanks for your post.

Drawing fewer objects would is more efficient and save resources compared to drawing a large number of objects on a chart.

Reusing tag names for a drawing object causes that specific drawing object to be updated. If you are looping through 100 tag names, it would limit the script to 100 new draw objects before the first object would be re-used.

Note that a tag name cannot be reused for a different object type. For example, a tag for a Line drawing cannot be used for a Rectangle drawing.

Please let me know if I may assist further.
