    OnRender always updating

    Is that normal that even not connected OnRender is continuously updating.

    I have written a Print statement to test this and I see my statement continuously printing ?
    How can it update when there are no ticks coming in ?

    That must be taking a lot of computer resources ...

    Thanks

    Hello,

    Thank you for the question.

    OnRender is called very frequently and is not based on tick or market data, this is the Render loop for the chart and is related to how the chart is Rendered.

    This would be expected, OnRender can be processor intensive if you are running a heavy calculation that takes a lot of time from OnRender on each frame, just Printing would not take much effort. This method should be called very frequently though so please keep that in mind with calculations you do as this method is strictly for Rendering visuals on the chart panel.

    Generally most calculations that are data related would go in OnBarUpdate or one of the market data overrides, you could then display the results of those calculations more freely using OnRender.


    Please let me know if I may be of further assistance.
