Thanks for your note.
There are no documented or supported methods or properties for suppressing the OnRender() method from triggering.
From the help guide: "The OnRender() method frequently runs once the State has reached State.Realtime in response to market data updates or a user interacting with the chart (e.g., clicking, resizing, rescaling, etc.)"
OnRender(): https://ninjatrader.com/support/help...8/onrender.htm
Let me know if I may assist further.
