Databox Price

[Devside_Victor]

Hello,

I have a question regarding the Price in the Databox: I cannot identify where the value comes from. I am trying to access it from a share service. I have access to the ChartPanel, ChartControl, Bars, but the only thing I could find is ChartBars.LastPrice but it is only one value, I was expecting an array. I need to be able to go back to a specific bar and get its price value.

Does someone know how I can access the price value of a specific bar from code?

Thank you.

Kind regards,
Victor

Hello Devside_Victor,

Thank you for your post.

You could use Bars.GetClose, Bars.GetOpen, etc to get the OHLC values for a given bar index. To do so, you would need to loop through the rendered bars on the chart and then call something like Bars.GetClose(barIndex) to get the Close price at the selected bar index.

See the help guide documentation below for examples and more information.

Hello Brandon,

Thank you very much for your quick response.

I can get the OHLC values without problems. My question was regarding the entry "Price" in the Databox (marked in yellow in attachment in the original post). Is there a way to get this value (or calculate if needed)?

Thank you again.

Kind regards

Hello Devside_Victor,

Thank you for that clarification.

Accessing the Data Box programmatically would not be possible. The Price value in the Data Box refers to the price where your cursor is. To get this value, you would need to use mouse coordinates and ChartScale.

Please see the attached example script that demonstrates how this would be accomplished. Note that ChartPanel.MouseMove is subscribed when the State == State.DataLoaded and unsubscribed when State == State.Terminated. OnRender() captures ChartScale into a private property. ChartingExtensions.ConvertToVerticalPixels converts the coordinate to device pixels. MyChartScale.GetValueByY converts to a price.

The output would be viewed in a New > NinjaScript Output window.
