Default Detecting lines within NT

I want to develop a strategy in NT7 that identifies lines from within NT. In other words, if an indicator plots horizontal lines, (fibs for example) I want to create a strategy that whenever horizontal lines are created by some indicator x, then execute the trade (even if the source behind those lines is unknown). There must be something within NT that can identify/detect when horizontal lines are plotted.

Hello RJBen,

Objects are only available outside of a class in C# if they are made public.

You may be able to create a public array to hold these objects and get information about the objects on each bar update. (It may be necessary to call Update() in the get).

I would recommend using a List object.

Hello RJBen,

The code below is general C# is and not specific to NinjaScript (meaning this is not documented in the help guide and isn't guaranteed).

The idea would be to create an array to hold the drawing objects.

Code:
private List<IDrawObject> myDrawingObjects;
Code:
myDrawingObjects = new List<IDrawObject>();
Make this public
Code:
[XmlIgnore()]
[Browsable(false)]
public List<IDrawObject> MyDrawingObjects
{
	get
	{
		Update();
		return myDrawingObjects;
	}
	set	{ }
}
And then as objects are drawn, these are added to the list.
Code:
myDrawingObjects.Add(DrawLine("myLineb", 30, High[0] + 2 * TickSize, 0, High[0] + 2 * TickSize, Color.Green));
Then the strategy would access that public property
Code:
if (MyIndicator().MyDrawingObjects != null)
{
	foreach (IDrawObject draw in MyIndicator().MyDrawingObjects)
	{
		if (draw is ILine)
		{
			ILine line = draw as ILine;

			Print(string.Format("{0}", line.StartY));
		}
	}
}

Futures, foreign currency and options trading contains substantial risk and is not for every investor. An investor could potentially lose all or more than the initial investment. Risk capital is money that can be lost without jeopardizing ones financial security or lifestyle. Only risk capital should be used for trading and only those with sufficient risk capital should consider trading. Past performance is not necessarily indicative of future results.

CFTC Rules 4.41 - Hypothetical or Simulated performance results have certain limitations, unlike an actual performance record, simulated results do not represent actual trading. Also, since the trades have not been executed, the results may have under-or-over compensated for the impact, if any, of certain market factors, such as lack of liquidity. Simulated trading programs in general are also subject to the fact that they are designed with the benefit of hindsight.
