DrawTriangleDown/UP size

[outsource]

Hello Support and All,

Is there a way to increase the size of the triangle in the DrawTriangleDown/Up comand?

Thanks

Hello outsource,

Thank you for writing in. There is not currently a documented way to increase the size of a triangle drawn using the DrawTriangleUp/Down methods. I would recommend creating a custom method to accomplish this inside the Plot override.

Please let me know if I may be of further assistance.

You can use DrawText() with the font Webdings. Characters "5" and "6" will show as triangles.

DrawText() allows for adjusting the font size, which translates into differrent sizes for the triangles.

Thanks,Harry,

could you please give an example?for the simple condition like this,for e.g.:

if(Low[0] < Open[0] && Close[0] > Open[0])

DrawText()

Thanks

private string                     triangleStringUp               = "5";

private Font                       triangleFont                    = null;
private int                         triangleFontSize              = 18;            
#endregion


protected override void OnStartUp()
{
       triangleFont = new Font("Webdings", triangleFontSize);
}

protected override void OnBarUpdate()
{
       DrawText("BearTrigger" + CurrentBar, true, triangleStringDown, 0, High[0] +        
       offset, triangleDownColor, triangleFont, pixelOffset, StringAlignment.Center,  
       Color.Transparent, Color.Transparent, 0);
}

You also need to declare variables for the offset and the triangleDownColor.

If you wish to adjust the size of the triangle you would need to create a property for the triangleFontSize.

I got errors - 'no overload takes 11 arguments'...Is that b/c you put Color.Transparent twice?

Forgot the pixelOffset. You can look up the exact syntax in the NinjaTrader Help Files. Just search for 'DrawText'. It is all explained.

Hello outsource,

The help guide document can be found here: http://ninjatrader.com/support/helpG...htsub=drawtext

The overload being used is the following:

DrawText(string tag, bool autoScale, string text, int barsAgo, double y, int yPixelOffset, Color textColor, Font font, StringAlignment alignment, Color outlineColor, Color areaColor, int areaOpacity)

An update to Harry's example might be:

DrawText("BearTrigger" + CurrentBar, true, triangleStringDown, 0, High[0] + TickSize * 2, 5, Color.Red, triangleFont, StringAlignment.Center, Color.Transparent, Color.Transparent, 0);

Please let me know if I may be of further assistance.

It depends on what you are trying to accomplish.

Hi,Sledge,

i`m trying to become God

Seriously,what i`m trying to accomplish?And how the HelpGuide can be helpful.It provides with examples that lack of the additional elements you want to insert.And when you insert them,you,occasionally, get errors.

You just need to copy and paste what is shown on the help file. It is not that difficult to do.

For the NinjaScript Draw() methods there are several overlaods.

This means that you can select the overload that fits your purpose and use it accordingly.

You have the choice which overload to copy and paste!
