Change the color of horizonal line

[alpurik]

I want to change the color of the horizontal line based on conditions but the entire line color is just showing the value based on the current bar. For previous bars it is not showing the color according to the EMA values of those bars. .

protected override void OnBarUpdate()
{

if (BarsInProgress != 0)
return;

if (CurrentBar < 5)
return;


if (ema_3[0] > ema_13[0] && ema_3[0] < ema_50[0])
{
MyBrush = Brushes.Yellow;
}
if (ema_3[0] > ema_13[0] && ema_3[0] > ema_50[0])
{
MyBrush = Brushes.Green;
}
if (ema_3[0] < ema_13[0] && ema_3[0] > ema_50[0])
{
MyBrush = Brushes.Yellow;
}
if (ema_3[0] < ema_13[0] && ema_3[0] < ema_50[0])
{
MyBrush = Brushes.Red;
}
Draw.HorizontalLine(this, "tag1", 0.1, MyBrush,DashStyleHelper.Solid,15,false);

}
}
}
Am I missing anything?

Hello alpurik,

Thank you for your post.

When MyBrush gets updated, it will change the color of the entire drawing object with the tag "tag1". You cannot change the color for just a segment/portion of a single Draw.HorizontalLine() drawing object.

To have a different color for different segments of the object, you would need to create separate Draw.HorizontalLine or Draw.Line() objects. Then, each line could have its own color.

Please let us know if you have any further questions.

Thanks Gaby. Can you please let me know what object should I use to generate a horizontal line like the one at the bottom of the image below which changes the color based on the respective bar?

Hello,

The screenshot looks like custom rendering using SharpDX. The Help Guide page for custom rendering is below:

https://ninjatrader.com/support/helpGuides/nt8/using_sharpdx_for_custom_chart_rendering.htm

We also have SampleCustomRender included in the platform which demonstrates custom rendering shapes and text using SharpDX.

Please let us know if you have any further questions.
