difference between "ChartControl" property and OnRender's "chartControl" argument

[ttodua]

I see case inside OnRender:

protected override void OnRender(ChartControl chartControl, ChartScale chartScale)
{
    if (ChartControl != null )....

}

So, can anyone finally say, what's difference between the argument `chartControl` (of OnRender) and the ChartControl property of indicator? can they be different, or they are literally same?

So, is there any difference if we used one or another inside OnRender?

Hello TazoTodua,

This is the same object being passed in, there should be no difference. The ChartControl is just a property of your script where the variable is being passed in directly. They contain the same value however depending on where you use ChartControl you may see a difference. ChartControl can be null depending on when it was used. The passed in value should not be null as OnRender would only be run in later states when the chart is present.



I look forward to being of further assistance.
