Draw Extended Line From Start to End Date.

[Shawn]

Hi,

I'm trying to figure out how to draw an extended line from a starting date to an ending date to be used for an indicator panel - lets say the ADL indicator. I've been working with the code below which works on the price panel based on a comparison of 10 bars back to present bar.. Thanks so much for your help..


if (CurrentBar < 10)return;

if (WilliamsR (14)[0] < -50 )
DrawExtendedLine("tag1", false, 10, High[10], 0, High[0], Color.Blue, DashStyle.Solid, 1);

Hi Shawn,

You can use .nets built in DateTime structure in NinjaScript. For working with extended line DateTime overloads, you place a date time object where expected. Help for working with DateTime objects is here:

Example:

#region Variables
private DateTime myDateTime = new DateTime(2011, 8, 11, 12, 0, 0);
#endregion

protected override void OnBarUpdate()
{
DrawExtendedLine("myELine", true, myDateTime, High[0], myDateTime.AddDays(1), High[0], Color.Blue, DashStyle.Solid, 2);
}

Feedback

Hi Ryan,

THanks for your feedback. I wanted to use this extended line for an indicator panel - not sure how to do that. I tried inserting the sample code you sent - but it didn't work . I'm probably doing something wrong... What would be the procedure for building this indicator?

That's a simple example, but you can modify the Y values for the indicator you want to draw the values at.

If you want the indicator's default panel to be something other than price, can add Overlay = false; to the script's Initialize() method.

It sounds as if your line is not being drawn in the panel as you expect?

If that is the case, you will need

 
DrawOnPricePanel = false;

in your Initialize() method.
