Hello turbofib,

Thank you for your post.

You would use Anchors to do this. Refer to our documentation at the following link: http://ninjatrader.com/support/helpG...us/anchors.htm
You can also refer to the details in the thread at the following link: http://ninjatrader.com/support/forum...d.php?p=449692

Please let me know if you have any questions.

hi,there are few example in the forum ..
I want to plot this line in the screen

https://gyazo.com/a8ba75d3f7794dad668e50d7bc6b3c8b

(i want to change parameter High and Low of the Line in the update)

i need 2 point not 3..

in you page :

http://ninjatrader.com/support/helpGuides/nt8/en-us/?anchors.htm

//defines the chart anchors used for the drawing tool
public ChartAnchor StartAnchor { get; set; }
public ChartAnchor MiddleAnchor { get; set; }
public ChartAnchor EndAnchor { get; set; }

public override IEnumerable<ChartAnchor> Anchors
{
get
{
return new[] { StartAnchor, MiddleAnchor, EndAnchor };
}
}



It defines 3 point..not 2..

I define only StartAnchor and EndANchor? (two point)

-Other question :

to use DrawLine..i do it in void OnRender(ChartControl chartControl, ChartScale chartScale)
or in OnBarUpdate() method?

- I dont find the sintax of script to draw the line with anchor..Can you give me an example?

Thanks

i try the example in help guide :

publicChartAnchor StartAnchor { get; set; }
publicChartAnchor MiddleAnchor { get; set; }
publicChartAnchor EndAnchor { get; set; }

protectedoverridevoid OnStateChange()
{
StartAnchor.DisplayName = "My Start Anchor";
MiddleAnchor.DisplayName = "My Middle Anchor";
EndAnchor.DisplayName = "My End Anchor";
}

publicoverrideIEnumerable<ChartAnchor> Anchors
{
get
{
returnnew[] { StartAnchor, MiddleAnchor, EndAnchor };
}
}
publicoverridevoid OnRender(ChartControl chartControl, ChartScale chartScale)
{
foreach (ChartAnchor anchor in Anchors)
{
Print(anchor.DisplayName);
}
}

turbofib,

You would DrawLine in OnBarUpdate for these purposes. You would not need to supply an Anchor but if you want to change the points after drawing them then you would loop through all objects and pull the anchors and change them.

So let's start from the beginning here. Is the object you wish to change the values of drawn from your script? Can you provide your script if so?

hi Patrick...i give you an exampe (is example with no sense...i know

if low[0]<low[10]
{
Line ff=Draw.Line(this, "mtUpHigh" + CurrentBar, false, 10, Low[10], 0, Low[0], Brushes.LimeGreen, DashStyleHelper.Dash, 1);
drawline=true;
}

If (drawline && low[0]>low[5])

===> change Low[0] in ff

[NinjaTrader_PatrickH]

This would be easier just to resubmit the drawing object with the new value. For example:

if low[0]<low[10] 
{
Line ff=Draw.Line(this, "mtUpHigh" + CurrentBar, false, 10, Low[10], 0, Low[0], Brushes.LimeGreen, DashStyleHelper.Dash, 1);
drawline=true;
}

If (drawline && low[0]>low[5])
Line ff=Draw.Line(this, "mtUpHigh" + CurrentBar, false, 10, Low[10], 0, Low[0], Brushes.LimeGreen, DashStyleHelper.Dash, 1);

ok..i understand this...
But if i want to get information about ths Line : CurrentBar and High Point in Line..

The items are available through the ILine object itself. Please refer to the documentation at the following link: http://ninjatrader.com/support/helpGuides/nt7/iline.htm
