Simple Code to make an object disappear after being touched by price

[gabmit1]

Hi there, I hope you are well.

I was wondering if someone had an example of code that could be used to make an object disappear in case of price touching it.

Example:
Use case example: draw lines at resistance and support levels
IF line is touched by price THEN make line disappear, and send out an alert.

I know how to delete the object, but i am wondering if you have any advice on how you would approach storing the line price (array?) and comparing it with current price.

Apologies if it's a bit of a newbie question, just trying to find the most efficient code to do so.

Thanks in advance.

Hello Gabriele,

Welcome to the NinjaTrader forums!

I'm not aware of any examples with this exact custom logic you are describing. This thread will remain open for any community members that would like to provide sample code.

If you have the drawing object saved to a variable, you can check the anchor price (or y-intercept between anchors) and then call RemoveDrawObject() with the tag name supplied.

private Line myLine;

myLine = (this, "tag1", false, 10, 1000, 0, 1001, Brushes.LimeGreen, DashStyleHelper.Dot, 2);

if (myLine != null && Close[0] >= myLine.StartAnchor.Price)
{
RemoveDrawObject(myLine.Tag);
}
