Indicator Clean up help

[imjustkaze]

i've coded this indicatro with AI, it does its job fine, but after maybe 10 minutes it causes a noticeable lag for my chart which goes away every time i refresh

i had another version of this i coded that didnt cause this... honestly i'm not quite sure what's causing it because i don't know how to code

could anyone help me with cleaning this up?

i'd also rather use lines than rectangles, but i can't get AI to properly draw lines no matter how much information i give it or examples from other indicators. Always end up with a dashstyle helper issue or something similar

Hello imjustkaze,

Please note, a basic understanding of C# programming is prerequisite to writing NinjaScript code.

Below is a link to a support article with helpful resources on getting started with C# and NinjaScript.

The performance impact may be caused by a large number of drawing objects.

From the help guide:
"When using Draw methods, a new instance of the Draw object is created including its custom rendering and calculation logic. These methods are convenient in many situations, but can quickly introduce performance issues if used too liberally. In some situations, you may see better performance for rendering via SharpDX in OnRender()."

Custom rendering the rectangles in OnRender() may alleviate the performance impact.

Included with NinjaTrader is the SampleCustomRender indicator which shows the basics of custom rendering.

I'm also including a link to an example of re-using brushes which can also decrease the performance impact.

Sorry for bumping, it sounds like your indicator might be creating too many objects or not properly cleaning up unused ones, which can cause lag. Try optimizing your code by limiting unnecessary redraws or reusing objects. For switching to lines, review examples of createLine or similar functions in your platform's documentation and ensure you're managing them efficiently to avoid helper issues.
