Errors

Hi Everyone,

I got these errors on the log while viewing a indicator on chart.Anyone help me to resolve these errors.

NinjaScript Chart rendering failed. There is likely a problem with a chart object's OnRender method. D2D error = 'Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index'

Default A direct X error has occurred while rendering the chart: HRESULT: [0x88990001], Module: [SharpDX.Direct2D1], ApiCode: [D2DERR_WRONG_STATE/WrongState], Message: Unknown

Hello,

Thanks for opening the thread.

I would first advise to start troubleshooting by commenting out any NinjaTrader drawing tools so you can focus on your rendering code. If the issue goes away after commenting out the drawing tools, we will want to look into this further on our end, so please let us know if that is the case.

These referencing errors are similar to the referencing errors that can be received in OnBarUpdate(). When referencing Series objects in OnRender(), it is advised to use the GetValueAt() and IsValidDataPointAt() methods to properly reference the Series. This is advised because OnRender() and OnBarUpdate() are not synchronized and direct references would not be guaranteed.

These errors are related to DirectX programming errors where the Chart fails to render. They typically have to do with calling SharpDX methods out of order or improperly. I would advise to simplify and double check your rendering implementation to troubleshoot further.

As these errors are to do with DirectX implementations through SharpDX, the MSDN resources for DirectX rendering may prove to be valuable resources for Development and debugging.
