ZigZag Lines

[Hawk Arps]

I am trying to create a custom 'ZigZag' tool, but when applied to the chart it will only draw the last two lines... how do I get NinjaScript to draw the zigzag lines over the entire range of price data?
I'm using the following code structure...wherein 'flipup' and 'flipdn' represent the bars on which a confirmed trend-change occurs.


if(flipdn)
{
{DrawLine("UpLine",false,CurrentBar-PvtBar[1],PvtPrice[1],PvtHiBarsBack,PivotHigh,Color.Blue,DashStyle.Soli d,2);}
}

if(flipup)
{
{DrawLine("DnLine",false,CurrentBar-PvtBar[1],PvtPrice[1],PvtLoBarsBack,PivotLow,Color.Red,DashStyle.Solid, 2);}
}

To draw multiple lines, your lines must have unique tags. The most common method used in these parts is to append the CurrentBar to a prefix. Using your syntax, your lines will then be tagged:

"UpLine" + CurrentBar.ToString()and
"DnLine" + CurrentBar.ToString()

respectively.

Is it possible to declare the color parameter as a variable which could be referenced by input options.
ie:
private Color UpColor =Color.Blue;
private Color trendcolor;

if (something){trendcolor=UpColor;}
DrawLine(.........,trendcolor,2);

Hi Hawk Arps,

Yes, this is possible. Please see this forum post which explains the approach:
