Hello ballboy11,

Thanks for your post.

Could you clarify on what exactly you are trying to refresh? We don't particularly recommend using ChartControl.InvalidateVisual to force a re-render, but this has been something that others have used. In a supported context, you could draw a drawing object and remove it right away with RemoveDrawObject.

If you are referring to fully reloading the indicator and reprocessing historical data, this isn't exactly supported either but could be accomplished with System.Windows.Forms.SendKeys.SendWait("{F5}");

If this information does not help, please elaborate on what exactly you need to have refreshed so we can share our insight.
