From DrawingTools namepace object, get High and Low of a bar that has been clicked on

[robbsadler]

I am trying to get the Bar object when it is clicked on from a drawing tool. I can't seem to find how to reference it. I can get to it from an indicator, but not sure how to get to the array with a DrawingTool. Do you have any examples I could leverage? I did quite a bit of searching and didn't find it.

I see ChartBars.Bars, but not sure how to index that (is 0 the main array of bars?) - I'm not new to C# but I'm a NT programming novice.

Hello robbsadler,

Thank you for your post.

You'd need to grab the ChartBars in the OnMouseDown method using GetAttachedToChartBars():

public override void OnMouseDown(ChartControl chartControl, ChartPanel chartPanel, ChartScale chartScale, ChartAnchor dataPoint)
{
// get the attached chart bars
ChartBars myBars = GetAttachedToChartBars();

int MyBarIdx = myBars.GetBarIdxByTime(chartControl, dataPoint.Time);
Print("High: " + myBars.Bars.GetHigh(MyBarIdx) + " | Low:" + myBars.Bars.GetLow(MyBarIdx));

// code continues

Thanks for the guidance - it was very helpful!

Now I am trying to go in the opposite direction from an OnBarUpdate event. How do I get the chartScale so I can call chartScale.GetYByValue?

Thanks again!

Hello robbsadler,

Thank you for your reply.

Is this in an indicator or strategy? Drawing Tools don't use OnBarUpdate.

Thanks in advance; I look forward to assisting you further.
