I have created my own public class (StopLoss, ProfitTarget, PositionLine, EntryOrder) for my own charttrader lines:


The values are stored in the base class (OnRender), for example:

if (positionLine != null) positionLine.OrderLabelRectX = rectXOrderLabelPos;

I also have a short video about it: https://youtu.be/uf-EdtDvUT0

they seem to be my problem now, with more than one chart. can anyone give me a helpful tip on how to solve the problem?

Hello sidlercom,

Thank you for your post.

Since NinjaTrader release 8.0.19.0 we now mandate NinjaTrader.Core.Globals.D2DFactory be used for custom rendering when needed and is accessed only in OnRender/OnRenderTargetChange.

See the help guide documentation below for more information.
D2DFactory - https://ninjatrader.com/support/help...d2dfactory.htm

Ultimately, debugging steps should be taken for custom rendering errors. I would suggest taking the following debugging steps.

Comment out and test various pieces of code that are rendering to find problematic part. Try to implement it in a separate script to focus on those rendering routines.

Make sure to create resources in OnRender and dispose of those resources at the end of OnRender. Ensure those resources work, then move to optimizing your resources with OnRenderTargetChange.

Make sure you understand the difference between device-dependent and device-independent resources, such as what needs a RenderTarget, and how to manage those resources. See the help guide below regarding device-dependent and device-independent resources.

Note that using dummy values with the rendering routines may help when testing.

If you find you are not getting D2D errors through your own script, isolate the issue. If D2D errors fall on items NinjaTrader items such as drawing tools or price markers (something you are not rendering yourself) please try to reproduce the issue and report it.
