Draw Line from Highest High to Lowest Low

[JBU1314]

Hi, I am trying to draw a line on the Price Panel from the Highest High to the Lowest Low in a 20 Bar Period. I just cant make it work. Could you please point me in the right direction? Here is what I tried:

double LowestLow, HighestHigh ;

protected override void OnBarUpdate()
{
LowestLow = MIN(Low, 20)[1];
HighestHigh = MAX(High, 20)[1];
Draw.Line(this, "", true, 20, (Convert.ToInt32(HighestHigh )), 1, (Convert.ToInt32(LowestLow)), Brushes.AliceBlue, DashStyleHelper.Dash, 2, true);

}

Hello JBU1314,

It looks like you are getting an error, please check the NinjaScript output window when you run this syntax.

This would be that you are not checking if there are enough bars available and that there is no Tag being used with the Line.

Please try something like the following:

protected override void OnBarUpdate()
{
	[B]if(CurrentBar < 20) return;[/B]
	LowestLow = MIN(Low, 20)[1];
	HighestHigh = MAX(High, 20)[1];
	Draw.Line(this, [B]"Tag"[/B], true, 20, (Convert.ToInt32(HighestHigh )), 1, (Convert.ToInt32(LowestLow)), Brushes.AliceBlue, DashStyleHelper.Dash, 2, true);
}

I look forward to being of further assistance.
