Refreshing the Chart

[DaveS]

With NT, charts refresh only when new data arrives. I have things going on that I would like to see without having to wait for the next tick. Is there a way to refresh a chart from within a NT script?

Thanks
Dave

You won't have anything happening in OnBarUpdate,

You'll need to use OnMarketDepth for bid/ask changes, or do some sort of timing interrupt.

Hi sledge
Thanks for your reply. Yes, I realised it would need to be outside OnBarUpdate.
I think its probably not possible in NT

Hello DaveS,

If you want to do some calculations regardless if there is any incoming ticks you would have to have a custom event with a timer object. You may view an example of this at the following thread.

You would have to create your own CustomEvent(), most probably a Timer() of some sort.

Why not just invalidate and update the ChartPanel when you have something ready to display?

public void Refresh()
        {
            m_ChartControl.ChartPanel.Invalidate();
            m_ChartControl.ChartPanel.Update();
        }

This, of course, repaints the panel immediately.

That code would still have to be called by the CustomEvent(), though I usually just use ChartControl.Refresh().
